The range was originally developed to address the challenges of tank bottom valves: no dead zone, self-draining and fully drainable, low pressure drop, the smallest possible weld-in flange diameter to bring the agitator closer to the centre of the tank, very simple maintenance since this valve is generally not accessible, diaphragms suited to the materials of pharmaceutical process tanks, and compact or right-angle actuators. This design was then extended to 2-way or 3-way valves, offering an aseptic alternative to the in-line diaphragm valve.

The range is modular. NovAseptic valve bodies are available in imperial sizes, from 1/2″ to 3″. On each body configuration with the same process connection diameter, all diaphragms, actuators and accessories of that same size can be fitted.

Interface for PTFE diaphragm, type 84

NovaSeptic range overview

NovaSeptic nomenclature and configurator

Interface for PTFE diaphragm, type 84

Mechanical link between PTFE diaphragm and NovAseptic actuator

Type 84 interface for NovAseptic valves, mandatory with the type 25 PTFE diaphragm. It provides the mechanical link between the rigid PTFE diaphragm and the actuator stem, a link that elastomer diaphragms make directly. Essential whenever a NovAseptic valve is fitted with a PTFE diaphragm.

Why an interface for the PTFE diaphragm

The PTFE diaphragm cannot be attached directly to the actuator stem like an elastomer diaphragm, because of its rigidity and lack of elastic memory. The type 84 interface makes this link: it transmits the actuator movement to the PTFE diaphragm without stressing it to the point of cracking.

The interface is specific to the type 25 PTFE diaphragm. EPDM, FKM and silicone diaphragms do not need it, as their flexibility allows direct attachment. Choosing a PTFE diaphragm therefore always involves the type 84 interface in the same diameter.

Without this interface, the PTFE diaphragm cannot be fitted. It is a component not to be forgotten in the bill of materials of a PTFE diaphragm valve; otherwise the valve is incomplete.

Characteristics

Frequently asked questions

Why an interface for PTFE only?

Because PTFE is rigid and has no elastic memory, unlike elastomers. It cannot be attached directly to the actuator stem without risk of cracking. The type 84 interface provides this link gently.

Is it needed with EPDM or FKM?

No. Elastomer diaphragms, EPDM, FKM and silicone, are attached directly thanks to their flexibility. The type 84 interface only concerns the type 25 PTFE diaphragm.

Is one interface needed per valve?

Yes, one interface in the valve diameter, whenever the valve is fitted with a PTFE diaphragm. It must be included in the bill of materials in the same way as the diaphragm.

The range was originally developed to address the challenges of tank bottom valves: no dead zone, self-draining and fully drainable, low pressure drop, the smallest possible weld-in flange diameter to bring the agitator closer to the centre of the tank, very simple maintenance since this valve is generally not accessible, diaphragms suited to the materials of pharmaceutical process tanks, and compact or right-angle actuators. This design was then extended to 2-way or 3-way valves, offering an aseptic alternative to the in-line diaphragm valve.

The range is modular. NovAseptic valve bodies are available in imperial sizes, from 1/2″ to 3″. On each body configuration with the same process connection diameter, all diaphragms, actuators and accessories of that same size can be fitted.

Limit switch boxes for NovAseptic valves

Inductive position detection, standard and ATEX versions

Inductive limit switch boxes for NovAseptic valves, for feeding back open and closed position to the PLC. Standard version type PA1251 and ATEX version type PA11-SEV for classified zones. They complement pneumatic actuator control with position feedback.

Role and selection

The limit switch box detects the position of the valve, open or closed, and feeds this information back to the control system. Detection is inductive and contactless, making it reliable and wear-free. It is the component that closes the control loop of an automated valve.

Inductive detection works without mechanical contact, eliminating wear and false contacts. The box confirms to the PLC that the valve has actually reached the commanded position, a prerequisite for reliable sequencing.

The ATEX version type PA11-SEV allows position feedback in explosive atmospheres, consistent with the AX110 ATEX actuator. On a classified line, both actuator and box must be ATEX.

Available versions

Compatible valve bodies

These accessories fit all NovAseptic bodies of the same diameter, tank bottom and process.

Frequently asked questions

What is the limit switch box for?

To confirm to the PLC that the valve has reached the commanded open or closed position. Without this feedback, automatic sequencing works blind. Inductive detection is contactless, and therefore wear-free.

When is the ATEX version needed?

In a classified explosive zone, with an actuator that is also ATEX. Type PA11-SEV goes hand in hand with the AX110 actuator.

Is it compatible with manual actuators?

The limit switch box is mainly used for automated control of pneumatic actuators. With manual operation, position feedback is of less value, since operation is visual and local.

The range was originally developed to address the challenges of tank bottom valves: no dead zone, self-draining and fully drainable, low pressure drop, the smallest possible weld-in flange diameter to bring the agitator closer to the centre of the tank, very simple maintenance since this valve is generally not accessible, diaphragms suited to the materials of pharmaceutical process tanks, and compact or right-angle actuators.

Pneumatic actuators for NovAseptic valves

Pneumatic control NC, NO or double position, all stainless steel, ATEX version available

Pneumatic actuators for NovAseptic valves, normally closed, normally open or double position. All-stainless or stainless steel base versions, and an ATEX version for classified zones. Remote control by compressed air, suitable for automated control and hard-to-reach valves. Fit all NovAseptic bodies of the same diameter, from 1/2″ to 3″.

Role and selection

The pneumatic actuator operates the valve by compressed air, enabling remote control and automation. The choice of fail-safe position, normally closed or normally open, defines how the valve behaves if the air supply fails. The double position handles three-way valves.

Normally closed, NC, closes the valve if the air supply fails, the default fail-safe position on most lines. Normally open, NO, leaves it open, chosen when flow continuity is the priority. The double position controls both diaphragms of a three-way valve.

The ATEX version type AX110 allows installation in explosive atmospheres. The all-stainless version suits washed areas, the stainless steel base with plastic handle suits less exposed installations.

Available versions

Compatible valve bodies

These accessories fit all NovAseptic bodies of the same diameter, tank bottom and process.

Frequently asked questions

NC or NO?

Normally closed closes the valve if the air supply fails; this is the default safety setting. Normally open leaves it open, chosen when flow continuity must be maintained. The choice depends on the safe state of your process.

When is the ATEX version needed?

In a classified explosive atmosphere. The type AX110 actuator is designed for these zones. Outside classified zones, the standard type 110 is sufficient.

How do I control a 3-way valve?

With the type 140 double-position actuator, which controls both diaphragms of the three-way body to divert or mix the flow.

Do they fit all bodies?

Yes, on all NovAseptic bodies of the same diameter, tank bottom and process alike.

The range was originally developed to address the challenges of tank bottom valves: no dead zone, self-draining and fully drainable, low pressure drop, the smallest possible weld-in flange diameter to bring the agitator closer to the centre of the tank, very simple maintenance since this valve is generally not accessible, diaphragms suited to the materials of pharmaceutical process tanks, and compact or right-angle actuators.

Manual actuators for NovAseptic valves

Manual operation, stainless steel or stainless steel base, autoclavable, disengageable or with right-angle drive

Manually operated actuators for NovAseptic valves, from the stainless steel base model with plastic handle to the all-stainless autoclavable model. Four versions depending on cleaning requirements, accessibility and the need for disengagement or a right-angle drive. Fit all NovAseptic bodies of the same diameter, from 1/2″ to 3″, tank bottom and process alike.

Role and selection

The manual actuator opens and closes the valve by hand, without compressed air or electrical power. It is the solution for locally controlled points, lines without an air network, and valves operated occasionally. Four versions cover cleaning and access constraints.

The choice depends on the environment and access. The all-stainless autoclavable model for washed and sterilised areas, the stainless steel base with plastic handle for controlled cost outside critical areas, the disengageable model to decouple operation, the right-angle drive to operate a hard-to-reach valve such as a tank bottom valve.

The type 180 right-angle drive offsets the control, which directly addresses the accessibility constraint of tank bottom valves, often installed beneath the tank.

Available versions

Compatible valve bodies

These accessories fit all NovAseptic bodies of the same diameter, tank bottom and process.

Frequently asked questions

Which manual actuator should I choose?

The all-stainless autoclavable type 170 in washed and sterilised areas. The stainless steel base with plastic handle type 150 outside critical areas. The disengageable NA12 170 to decouple control. The type 180 right-angle drive on a hard-to-reach valve.

Why a right-angle drive?

To operate a valve installed in a hard-to-reach location, typically a tank bottom valve located beneath the tank. The right-angle drive offsets the handle to a position the operator can reach.

Do they fit all bodies?

Yes, on all NovAseptic bodies of the same diameter, tank bottom and process alike. Modularity guarantees interchangeability at equal diameter.

Diaphragm data sheet

NovaSeptic range overview

PTFE diaphragm for NovAseptic valves, with type 84 interface, FDA and USP Class VI, 1/2″ to 3″

PTFE type 25 diaphragm for NovAseptic valves, in contact with the product. FDA and USP Class VI compliant. Wide service range, depending on the process. Fits all NovAseptic valve bodies of the same diameter, from 1/2″ to 3″, tank bottom and process alike. Requires the type 84 interface.

Where this diaphragm is the right choice

PTFE offers the broadest chemical inertness: it resists almost all pharmaceutical products and aggressive fluids that elastomers cannot withstand. It is the diaphragm for severe chemical processes and maximum purity requirements.

PTFE is rigid and less flexible than an elastomer. It requires the type 84 interface, which provides the mechanical link between the PTFE diaphragm and the actuator. On a simple aqueous circuit, EPDM is sufficient and costs less.

The diaphragm: the product-contact component

In a diaphragm valve, the diaphragm is the only component in contact with the product. It provides the seal and separates the fluid from the actuator. Its selection determines chemical compatibility, allowable temperature and valve service life.

The diaphragm is the consumable part of the valve: it is replaced periodically, without removing the body. Its material is chosen based on the fluid and temperature, independently of the body and actuator.

The type 25 PTFE diaphragm requires the type 84 interface, which provides the mechanical link between the rigid diaphragm and the actuator stem. This interface is specific to PTFE; elastomer diaphragms do not need it.

Characteristics

Compatible valve bodies

Frequently asked questions

Which diaphragm for my process?

EPDM for aqueous media, water and low-pressure steam. FKM for oils, solvents and high temperature. PTFE for maximum chemical inertness. Silicone for flexibility and food applications. The choice depends on the fluid and operating temperature.

Why a type 84 interface?

The PTFE diaphragm is rigid and cannot be attached directly to the actuator stem like an elastomer. The type 84 interface provides this mechanical link. It is specific to PTFE.

Can the diaphragm be changed without removing the valve?

Yes. The diaphragm is the consumable part of the valve; it is replaced without removing the welded body, which is a key point of NovAseptic maintenance, particularly on hard-to-reach tank bottoms.

Which bodies does it fit?

All NovAseptic bodies of the same diameter, tank bottom and process alike. The modularity of the range guarantees interchangeability at equal diameter.

Silicone diaphragm for NovAseptic valves, FDA and USP Class VI, 1/2″ to 3″

Silicone type 26 diaphragm for NovAseptic valves, in contact with the product. FDA and USP Class VI compliant. Wide service range. Fits all NovAseptic valve bodies of the same diameter, from 1/2″ to 3″, tank bottom and process alike.

Where this diaphragm is the right choice

Silicone is the most flexible diaphragm, suited to food applications and points where flexibility is the priority. Low extractables, good resistance to high and low temperatures, valued in pharmaceuticals for its low leachables profile.

Silicone has poor resistance to certain solvents and oxidising agents, and low tear and abrasion resistance, which limits its service life at points dismantled very frequently. It has neither the chemical resistance of PTFE nor the oil resistance of FKM.

FKM Viton diaphragm for NovAseptic valves, FDA and USP Class VI, 1/2″ to 3″

FKM Viton type 24 diaphragm for NovAseptic valves, in contact with the product. FDA and USP Class VI compliant. Service range -34 °C to +204 °C. Fits all NovAseptic valve bodies of the same diameter, from 1/2″ to 3″, tank bottom and process alike.

Where this diaphragm is the right choice

FKM withstands oils, fats, solvents and acids, up to 204 °C. It is the diaphragm for fatty processes, solvent lines and hot points where EPDM fails. Low gas permeability, good ozone resistance.

FKM is less effective with strongly oxidising products, concentrated nitric acid, high-concentration hydrogen peroxide. Less flexible than EPDM, it requires careful face finish and tightening, and costs more. On a purely aqueous circuit, EPDM remains preferable.
