2/2 way air operated valve
70 - 860 l/min, max. 16 bar
Valve is controlled by pilot fluid (air, water) acting on the diaphragm which separates it from the main fluid. In its basic position, the valve is held open by means of spring force. When pilot fluid is applied the valve closes. Valve opens when the coil is energised and shuts off the pilot fluid. Pilot fluid is exhausted through pipe vent. Required pilot pressure is 1 bar over the main fluid pressure, however, it must not exceed 8 bar.
