High Containment Powder Valve

High Containment Powder Valve

Features:

1. Low retention, no dead corner, high cleanliness, and small torque.
2. The airbag and plunger have no friction, so that the service life of the valve is extended.
Suitable for: fluids, powders, granules, and other materials.
Valve core material: PTFE + metal scraper/PEEK/PTFE/metal; others available.
Airbag material: SI/EPDM/FKM/FFKM; others available.

1. See sampling valve in closing condition

1. Open relief valve (relief pressure of airbag)
2. Rotate the booster valve handwheel, and the internal of the booster valve will be filled with air.
3. Close the relief valve.

1. Rotate the main valve handwheel until the valve core fully retracts.
2. The material will go into the sampling port.

1. Rotate the main valve handwheel to push the material back into the container.

1. Rotate the booster valve handwheel until the airbag gets inflated into sealing, and observe the pressure gauge at 1 bar.
2. Close the valve.

Our High Containment Powder Valve is specifically designed for the safe, dust-free transfer of potent or sensitive powders in pharmaceutical, biotech, and fine chemical applications.
Engineered with precision sealing and a split-valve containment concept, it ensures maximum operator safety and zero cross-contamination during charging or discharging operations.

Key features include:

High containment performance—designed to achieve containment levels down to OEB 5 / <1 µg/m³.
Smooth, crevice-free flow path for easy cleaning and minimal powder retention.
Modular design compatible with a wide range of vessels, isolators, and process equipment.
Material options: Stainless steel 316L, Hastelloy, or customized alloys for aggressive media.
Sealing materials: EPDM, FKM, or PTFE to meet FDA and USP Class VI standards.
Optional automation for integrated control and CIP/SIP compatibility.
Ideal for applications in API handling, reactor feeding, charging/blending, and packaging lines, this valve provides the highest containment integrity while maintaining operational efficiency and reliability.
