Description
Operation description:
VP-NDV type throttle/check valves are used to throttle the pilot and main flow of hydraulic fluid in lines Aand B. These valves consist of two throttles that have adjusting screws and two check valves that are built into the housing.
From the V direction to the P direction (see hydraulic symbol), the hydraulic fluid flows through the check valve with a low pressure loss.
And from the P direction to the V direction, the flow of hydraulic fluid is throttled depending on the throttle adjustment.
