Pressure Reducing Valves / Pressure Reducing and Check Valves
Pressure reducing valves are used to set the pressure of a hydraulic circuit below that of the main circuit. In addition,
operation under remote control is possible by using the remote control port. Pressure reducing and check valves have
check valves, which allow a free flow from the secondary side to the primary.

The max. flow rates are those shown at the primary pressure at 21 MPa (3050 PSI).
The drain flow rates are equal to pilot flow rates when differential pressure between
primary and secondary pressure is at 20.5 MPa (2970 PSI).

Sub-plates are available. Specify the sub-plate model number from the table above. When sub-plates are not used, the mounting
surface should have a good machined finish.
The sub-plates are the same as those for H type pressure control valves. With the reducing and check valve, the sub-plate is used in a
position 180° turned (upside down) from the normal position. When mounting the sub-plate, be sure to bring the valve locating pin to
the sub-plate pin hole. For dimensions, see
page 244 to 246.
To adjust the pressure, loosen the lock nut and turn the pressure adjustment handle slowly clockwise for higher
pressures and anti-clockwise for lower pressures. After adjustments, do not forget to tighten the lock nut.
Connect the drain port directly to the reservoir in which case the pressure at the drain port should be kept at a low
back pressure close to the atmospheric pressure.
In case of "Threaded Connections", there are two threaded connection type primary pressure ports. They can be
connected each other in-line; one as an inlet and the other as an outlet or the valve can be used by plugging one of the
pressure ports.

For any other viscosity, multiply the factors in the table below.
P'= P (G'/0.850)
For any other specific gravity (G'), the pressure drop ( P') may be obtained
from the formula below.
