pilot operated directional valves of Pressure Centered Type (3H*) andmodels with Pilot Piston (P*), those valves cannot be used in combination
with modular valves.

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
model number from the table below.

Note: The mounting surface of shaded parts above has a good machined finish. (1.6 )Interchangeability in Installation between Current and New Design
06 Series Modular Valves have changed from 30 to 70 design numbers model to operate higher max. pressure. The
mounting surface has no changes.
But if use the operating pressure as more than 25 MPa, have to select design No. 70 bolt kits (MBK-06).

Mounting bolt kits of design No. 70, the length of both sides screw is different, so refer to the stacking example about 06
series model valves on page F-96.
If current and new designs in mixed use, the max. pressure is equal to the current design's pressure.
