This is a pilot-operated standard balanced, spool-type, proportional reducing/relieving valve. It is intended for use as a pressure control device, increasing the current supplied to the coil will proportionally increase the pressure setting. It reduces a high primary pressure at the port 2 to a constant reduced pressure at port 3, with a relief function from port 3 to port 2. Once a sufficient pressure is applied at port 3 exceeds the regulated pressure set by the input electrical current, flow from port 3 is relieved to tank via port 4 (tank).
-
The maximum control flow pilot flow is approximately 1500 cc/min at 200 bar.
-
Reseat pressure exceeds 85% of cracking pressure.
-
Back pressure at port 4 is directly added to the valve setting at a 1:1 ratio.
-
Dither frequency should be adjustable between 80-300 Hz (recommended frequency: 85 Hz).
-
There is a filter installed at port 2
-
Continuous-duty rated coil.
-
Efficient wet-armature construction.
-
Working parts are heat-treated and high-precision ground to increase hardness for long life.
