Detail Information
DN25 PN10 Pneumatic Diaphragm Valve, RF, Stainless Steel.
Quick Detail
Weir-type diaphragm valves:
The weir-type diaphragm valve is one of the most common designs available. The raised lip/saddle design is best suited for small flow control and is kept leak-proof thanks to the bonnet over the diaphragm and actuator. This design is optimal for dangerous or corrosive liquid and gas, as any failure with the membrane will be kept contained by this bonnet.

Dervos Inspection after Valve Assembly
Valve quality is one of perspectives we care about most. In Dervos, quality control starts from raw material, machining, assembly to pre-shipment inspection.
After assembly, the quality checking team will do visual checking, dimension checking, hydraulic testing and air testing. Every order must pass the test per inspection standards. Otherwise our quality checking team will not release the shipment.
