    Diaphragm Valves

J.L. Wingert offers a wide selection of Griswold diaphragm valves suited for most any application.  Griswold diaphragm valves come actuated, hydraulically self closing, pressure regulated, solenoid actuated, and liquid level controlled.  Griswold valves do not have screens or small orifices in the control mechanism that are subject to clogging, which is the main reason most diaphragm actuated valves fail.  No screen and self cleaning, self purging, slow closing, and no hammer or chatter are just a few good reason to choose a Griswold diaphragm valve over the competition.
