3 way single pilot operated check valves, in line

These valves are used to block the cylinder in one direction. The flow is free in one direction and blocked in the reverse direction until pilot pressure is applied.
They are designed for in-line mounting.

Hlpe06- integrated circuit hi-low pressure with solenoid valve

In a circuit powered by two pumps in parallel, this valve is used to discharge the pump with the highest flow rate when a certain calibration value is reached. From this moment on, the actuator works with the lower flow pump at higher pressure, consuming less energy.
