			Diaphragm valve is a monoblock bidirectional valve. Depending on the application, different quality of the body and rubber lining solutions can be given.
The main features of the valve:
100% leak tightness performance guaranteed
The valve can be installed in any position
Produced with high EU quality components
Easy maintenance: Three part design allows maintenance and actuator retrotitting without removing the valve body from the pipeline.
Handwheel: comfortable grip, easy to use for fast operation, saves time and effort.
Stem designed to reduce friction for low operating torque.
Diaphragm: provide positive shutoff and isolates all working parts from line fluid.
Full flow and low pressure drop
