Manual Diaphragm Valves

iPolymer Manual Diaphragm Valves are design for Quarter-Turn manual actuation of our popular Pneumatic and Solenoid configured Miniature Diaphragm Valves. Offered as a 2-Way PTFE Valves, these valves are similar to our Precision Plug Valve. Rather than a stem plug, the valves utilize a flexible diaphragm hard seat seal. As manual valves, they are operated by hand. Used where pneumatic and electrical connections are not practical or not necessary. These Diaphragm Valves provide unsurpassed chemical compatibility with a wide range of media. The all wetted PTFE body, valve stem and one piece diaphragm maintain a material inert boundary for ultra clean applications.
