Pneumatically Actuated, Plastic Diaphragm Valve, Type 740

Pneumatically Actuated Diaphragm Valves - Type 740

The Chemline Type 740 Pneumatically Actuated Diaphragm Valve (formerly 400 Series) features a plastic piston actuator, field reversible normally closed to normally open. It offers compact dimension and long cycling life at a cost lower than pneumatically actuated ball valves.

The Type 740 is part of the 700 Series of diaphragm valves.They feature interchangeable bodies, diaphragms and actuators. Modular construction minimizes spare parts requirements. All major parts are solid plastic, corrosion resistant and light weight to minimize stress on plastic piping. Being a diaphragm valve, it is available for sanitary or slurry applications. With a Teflon diaphragm, it has corrosion resistance superior to ball or butterfly valves.
