Product Description

SS316L Stainless Steel Pharmaceutical Grade Pneumatic Diaphragm Membrane Valve
with Regulator

A is a hygienic flow control device widely used in industries like pharmaceuticals, food and beverage, and biotechnology. It uses compressed air to actuate a diaphragm, which isolates the process media from the valve mechanism. The design ensures leak-proof operation, supports CIP/SIP cleaning, and prevents cross-contamination. Its smooth internal surface reduces residue buildup, making it ideal for ultra-clean environments requiring precise, sterile fluid control.

Working Principle
The stainless steel sanitary pneumatic diaphragm valve operates by using compressed air to move a piston or actuator, which in turn pushes the diaphragm against the valve seat to stop flow. When air pressure is released, a spring returns the diaphragm to its open position, allowing fluid to pass through. The diaphragm isolates the working parts from the media, ensuring no contamination. Its design allows for accurate control, smooth operation, and is ideal for sterile processing environments.

 

Size Range: DN15-DN100 (1/2"-4")

Product Description

Stainless steel sanitary valves are widely used in high-cleanliness industries and have the following significant feature:
1. Compact Diaphragm Chamber Design
The actuator and diaphragm chamber are integrated for faster response, reducing dead space and improving hygienic control.

2. Fully Drainable Body Structure
The sloped internal contour ensures complete drainage, minimizing residue and risk of cross-contamination in CIP/SIP processes.

3. Tool-Free Diaphragm Replacement
Quick-mount bonnet design allows easy diaphragm change, reducing downtime and simplifying maintenance procedures.

 

4. Internal Mirror Polishing Finish
Surface roughness ≤ 0.8μm with optional Ra ≤ 0.4μm provides superior cleanability in ultra-hygienic environments.

5. Multi-Angle Flow Orientation Options
Available in weir, zero dead-leg, and T-body versions for flexible installation, suiting tight spaces and specific flow needs.

6.Position Feedback & Control Integration
Compatible with control heads and sensors for automated feedback, supporting Industry 4.0-ready process systems.
