Product Description

Stainless Steel 3 way pneumatic PTFE lined sanitary saunders electrical U type manual weir Diaphragm Valve (JN-DV1004)

The Stainless Steel 3-way pneumatic PTFE-lined sanitary Saunders U-type manual weir diaphragm valve controls fluid flow by lifting or lowering a flexible diaphragm against a weir. Pneumatic actuation enables automated switching between flow paths, while the PTFE lining ensures chemical resistance and tight sealing. The U-shaped weir design minimizes dead zones for hygienic operation, suitable for aseptic processes.
