Sanitary Tri Clamp GEMU Diaphragm Valve
The Weir-Type GEMU Diaphragm Valve is a premium sanitary valve engineered with a raised weir (saddle) across the flow bore. The flexible diaphragm seats against the weir to provide bubble-tight shut-off with minimal actuating force. This design minimises residual volume in the valve body, making it ideal for applications where complete drainability and cleanability are critical. It is manufactured to GEMU precision standards and fully meets international hygienic requirements.
