5.0 PRV1 AND PRV5 PRESSURE REDUCING VALVE
The 2-way pressure reducing valve regulates system pressure for
all subsequent valves including their consumers according to the
set pressure (serial connection). The PRV1 and PRV5 have a
check valve that prevents a pressure drop on the secondary side, if
pressure on the primary side drops below the set pressure of the
pressure reducing valve, due to e.g., switching operations of
primary side consumers. The pressure reducing valve can be
adjusted by turning adjustment screw in or out.
secondary hydraulic circuit should be set using a pressure gage.
When desired setting is achieved, the lock-nut should be tightened.
