General Description
These adjustable pressure relief valves limit system pressure by directing pump flow to reservoir when the system pressure reaches the setting of the valve, thus preventing overloading the system. Their two-stage design ensures fast response and minimal pressure override. In addition to the conventional relief valve operation, a pilot venting feature allows the system pressure to be dropped to near-zero, or to a low-level pressure.
The valve is available in two versions: type ECT5, with integral solenoid operated pilot valve, and in basic form,type ECT.
In the “ECT5” version, the pilot valve provides for selection of up to three pressures or one/two pressures plus off-loading according to the model type.
The circuitry options can be further extended by the use of remote control
valves. In both the “ECT” and “ECT5” versions the “Vent” port can be connected to an on/off valve for load/unload, or to a pressure pilot valve for remote control of
the pressure setting.
For both models the integral manual pressure adjustment is available as
screw/locknut, or micrometer with keylock.
