Technical Feature
OPERATION:
The valve with spring chamber port“Y”external drain, prevents flow from port“A”to
port“B” until pressure at port“A”exceeds the set Cracking Pressure and opens
the pilot section. The pilot flow creates a pressure differential across the poppet which
causes the valve to open allowing flow from port“A” to port“B” protecting the
circuit from over pressurization;
With Port“X”connected to tank(usually controlled by a solenoid directional valve),the
valve can be converted in such a way that it is capable of being electrically to nonpressurized circulation.(main piston is open). -
