F-106★1. Because drain ports "V" and "W" are not provided for solenoid
controlled pilot operated directional valves of Pressure Centered Type(3H*) and models with Pilot Piston (P*), those valves cannot be
used in combination with modular valves.

■ Instructions●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 internal drain type (with T).

●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 clockwise. Be
sure to re-tighten the lock nut firmly after making adjustment to the pressure.

Mounting Bolt Kits For Modular Valves
Valves are mounted with six stud bolts. Valve combination varies according tothe 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
