Sanitary Pneumatic Diaphragm Valve
KINGMAN supplies sanitary pneumatic mushroom-head diaphragm valves. Fitted with mushroom-head pneumatic actuator, it features compact outline, small installation footprint and fast response. The aging-resistant actuator housing adapts to cleanroom environment with stable and reliable pneumatic switching. The valve body adopts sanitary residue-free weir type structure with high-gloss inner polishing and supports CIP/SIP sterilization. As the only medium-contacting sealing component, the diaphragm separates fluid from driving parts. It is suitable for automatic on-off control of food and pharmaceutical fluid pipelines in limited-space areas. Diaphragm materials can be selected according to process fluids.

Diaphragm
Different from the traditional diaphragm valve body, the aseptic diaphragm valve body has a sealing protrusion that tightly snaps on the inner diameter, which can reduce the annular gap between the diaphragm and the valve body. This feature of the diaphragm valve makes it particularly suitable for aseptic processe.
Diaphragm Material
Diaphragms are available in EPDM rubber and TFM rubber, with single and double diaphragms optional. The dual diaphragm design allows the two diaphragms to operate independently,which reduces tension caused by different thermal properties. Each application has different operating conditions and therefore different requirements for the diaphragm. To select the diaphragm that is best for you, consider the following factors: operating pressure, application temperature, process fluid. EPDM can be suitable for most application conditions, and some high-temperature conditions require the use of TFM material diaphragms.

Features
- Compact mushroom-head pneumatic actuator saves installation space, perfect for densely arranged pipelines in cleanrooms.
- Simplified pneumatic transmission delivers fast response for rapid fluid on-off control.
- Aging-resistant actuator housing is dust-proof, moisture-proof and tolerant to sterilization steam, resisting dust and rust in clean environments.
- Residue-free weir-style valve body with high-gloss polished bore, compatible with automatic CIP/SIP cleaning and sterilization.
- Only the diaphragm contacts process fluid; all driving components are isolated to reduce contamination risk.
- Diaphragm materials can be selected according to media properties for differentiated sanitary applications in food and pharmaceutical industries.
Working Principle

The compact mushroom-head pneumatic actuator uses compressed air to drive internal piston motion. Air pressure pushes the piston to act on the stem, pressing the diaphragm against the weir for shutoff. When air pressure is released, the built-in return spring pulls the piston and stem back, lifting the diaphragm and opening the flow channel. The streamlined small footprint actuator shortens force transmission travel for rapid response. Only the diaphragm contacts the process fluid, while all pneumatic and moving components stay outside the media zone. This isolated working principle prevents lubricant or actuator debris from entering pipelines, perfectly matching confined-space cleanroom sanitary piping.
