use solenoid controlled pilot operated directional valves with these modular valves, please
select the internal drain type (T-line).

PT Y X BAPMRA-04●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 tore-tighten the lock nut firmly after making adjustment to the pressure.

Mounting Bolt Kits For Modular Valves
Valves are mounted with six stud bolts (M6×2, M10×4). 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 togive the bolt kit model number from the table below.
