In the pressure adjustment ranges "A" and "B", maximum flow rates are
limited by the pressure setting on the secondary side.
Referring to the secondary pressure vs. maximum flow characteristics on
the following page, use the valve at the maximum flow rate within a
zone highlighted with .

Instructions Graphic Symbols

Connect Drain Line (Y port) to oil tank independently
so as to obtain stable pressure setting. At the same time,
the solenoid controlled pilot operated directional valve
to be used in combination with this valve must be of P T Y X B A

internal drain type (with T). MRP-10

To make pressure adjustment, loosen the lock nut and

turn the pressure adjustment screw clockwise or anti-
clockwise. For an increase of pressure, turn the screw
P T Y X B A
clockwise. Be sure to re-tighten the lock nut firmly after
MRA-10
making adjustment to the pressure.

 Mounting Bolt Kits For Modular Valves
Valves are mounted with six stud bolts. Valve combination
varies according to the circuit type. Hence, the mounting
bolt kits are available on a combination type basis. When
ordering the mounting bolt kit, be sure to give the bolt kit
