The Chemline Type 730 Pneumatically Actuated Diaphragm Valve (formerly 700 Series) features a plastic diaphragm actuator, either normally closed, normally open or double acting. This valve offers long cycling life, high pressure resistance and a size range 1/2" to 4". 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. This becomes an economical control valve when a positioner is added.
The Type 730 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.
