AutomationDirect’s NITRA brand of pneumatic products now includes new 22-mm pushbutton and switch pilot devices intended for use with pneumatic valve bodies. These pneumatic pushbuttons can also combine valve bodies and electrical contact blocks. ECP series 22 mm 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 22-mm electrical pushbutton hole.
Available pneumatic pushbutton operators include momentary pushbuttons with 30-mm flush and extended round heads, 40- and 60-mm round head mushroom pushbuttons, key operated 40-mm round head mushroom pushbuttons, double-headed green/red rectangular pushbuttons, knob and long lever selector switches, plus 2 and 3 position key selector switches.
NITRA pneumatic pushbutton operators start at $2.75 and are backed by a one-year warranty.
The EVP series manual valves that are used with NITRA pneumatic pushbuttons and switches also function as pneumatic limit switches. These plunger valves are 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.
