IMI PBM 2-Way Ball Valve
Sanitary 2-way ball valve, IMI PBM Igenix® range
IMI PBM Valve Solutions – Ball valve for clean fluids, sterile processes and pure steam
The IMI PBM 2-way range is designed for processes where a standard ball valve is no longer sufficient: WFI and PW networks, pure steam, active ingredient transfer, sterile sampling points, CIP/SIP loops with repeated cycles.
Three-piece swing-out body design allowing inspection, seat replacement and cleaning without dismantling the pipework.
Used in pharmaceuticals, biotechnology, fine chemicals, cosmetics and food processing with high hygienic requirements.
Two main series
| Series | Body type | Standard ID Ra | Target applications |
| Forged Series 8 | Forged low-ferrite 316L body | 0.38 µm EP / 0.51 µm (20 µin) | High-purity pharma applications, WFI, pure steam |
| Cast Series 9 | Cast low-ferrite 316L body | ≤ 0.76 µm (30 µin) | Sanitary, food processing and cosmetics applications |
Mechanical finishes and electropolishing available for both series.
Surface treatments performed without animal-derived ingredients (ADI-free), compliant with current pharma requirements.
Body and wetted-part materials
Low-ferrite 316L stainless steel as standard, forged (Series 8) or cast (Series 9).
Alternatives available in AL-6XN® (UNS N08367) for chloride-bearing fluids, and in Hastelloy® C-22 (UNS N06022) for extremely corrosive media.
Composition and traceability compliant with ASME BPE. 3.1 material certificate supplied for all wetted parts.
Seats, seals and sealing
Standard V-TEF™ (modified PTFE) seats and seals. FKM and EPDM alternatives available depending on chemical compatibility and temperature.
USP Class VI elastomers, FDA-compliant materials.
Bidirectional bubble-tight sealing upstream and downstream, allowing cleaning, purging and draining of the valve body without removal. Full vacuum rated as standard.
Adjust-O-Seal® technology
Progressive tightening of the seats against the ball by adjusting the body bolts, in-line, without dismantling or process interruption.
Compensates for normal seat wear over cycles and extends the valve’s service life.
Elimination of O-rings in the fluid path, removing as many retention and potential contamination points.
Process options
Several configurations available depending on hygienic requirements:
Purge holes in the ball for in-line CIP. Milled flats to prevent clogging.
Self-flushing ball for loaded or viscous products.
Body cavity fillers to minimise retention zones and the risk of cross-contamination.
Clean Steam and Steam Trap configuration available with integrated purge ports.
Dimensions and connections
Sizes available from 1/4″ to 6″ (DN 8 to DN 150).
Optional True-Bore® design, with a bore diameter equal to the inside diameter of the connected tube or pipe, eliminating in-line restrictions and turbulence.
Available connections: hygienic clamp (Tri-Clamp), extended tube ends for orbital welding, sanitary thread, flanges to specification.
Compatible with ASME BPE, DIN 11864 and SMS dimensional standards.
Operating range
Operating pressure up to 62.1 bar (900 psig) depending on series and seat material.
Temperature up to 232 °C with V-TEF™ seats. Reduced ranges with FKM or EPDM seals depending on compatibility.
Actuation
Manual operation by standard handle or patented lockable handle.
Integrated Direct Mount Actuation interface on the stem axis, ensuring precise alignment with the pneumatic or electric actuator and extending cycle life.
Full range of actuators, limit switch boxes and positioners available.
Traceability and packaging
Each valve is supplied with a 3.1 material certificate according to EN 10204 for all wetted parts (CMTR), a USP Class VI declaration of conformity for elastomers and an FDA statement for product-contact materials.
Laser marking on the body: reference, size, material, serial number.
Individually packed in a polyethylene sleeve, with capped ends.
