H Type Pressure Control Valves
These valves are hydraulically damped, direct operated, pressure control
valves which can be actuated by internal or external pilot pressure. There
are various types of valve including sequence, unloading and low
pressure relief valves, all of which are operated by a pressure rise in the
circuit, sensed either internally or remotely.

*3 Type 1 is only possible for pressure adjustment ranges L and M.
*4 Model with auxiliary pilots are used where valves must be operated under a lower external pilot pressure than the
adjusted pressure (types N, A and B about 1/8 of adjusted pressure; type C: about 1/16). This does not apply to
pressure adjustment ranges L and M, and valve type 1.

■ Instructions
To adjust the pressure, loosen the lock nut and turn the pressure adjustment screw slowly clockwise to increase
pressure or anti-clockwise to decrease pressure. After adjustments, do not forget to tighten the lock nut.
Connect the secondary side pressure ports of types 1 and 4 (internal drain) and the drain ports of types 2 and
3 (external drain) directly to the tanks with a back pressure close to the atmospheric pressure.
There are two threaded connection primary pressure ports. They can be connected each other in-line; one
as inlet and the other as an outlet or the valve can be used by plugging one of the pressure ports.

Description
Can be used as low-
pressure relief valve, but
be careful to occurrence of
surge pressure.
Used to control the
operational sequence of 2
or more actuators. If
primary pressure exceeds
the pressure setting,
effective fluid is delivered
to the secondary side.
Used for the same
purpose as for the type 2.
Operated by external pilot
pressure irrespective of
primary pressure.
Used as unloading valve.
If external pilot pressure
exceeds the pressure
setting, the pump is turned
no-load by releasing all
fluid to the tank.

HC Type Pressure Control Valves
These valves are hydraulically damped, direct
operated, pressure control valves which can be
actuated by internal or external pilot pressure.
They are available with integral check valves for
use when reverse free flow from the secondary
port to the primary port is desired. There are
various types of valve including sequence
counterbalance valves, all of which are operated
by a pressure rise in the circuit, sensed either
internally or remotely.

adjusted pressure (types N, A and B: about 1/8 of adjusted pressure; type C: about 1/16). This does not apply to
