ECP series 22mm pneumatic pushbuttons and switches are used with EVP series valve bodies to create manual valve assemblies, or hybrid electro-pneumatic actuators. These operators allow mounting up to two 3-way valves, or one valve and one to three ECX series electrical contact blocks. The operators fit in a standard 22mm pushbutton hole. Available pneumatic pushbutton operators start at $2.75 and include momentary flush & extended pushbuttons, mushroom pushbuttons (also key operated), double-headed pushbuttons, and knob selector and key selector switches. The EVP series manual valves also function as pneumatic limit switches. These plunger valves are available in roller, one-way roller, thru panel and flush mounting versions. Starting at $16.00, the valves have 5/32-inch push-to-connect pneumatic connections in axial or side port configurations.
