RELIEF VALVE BALANCE PISTON TYPE（HR） SIZE 02
The balance piston type relief valve regulates the maximum pressure in the hydraulic circuit
to maintain the pressure in the circuit at a constant pressure.

■Features

1. The balance piston type design offers excellent pressure - flow characteristics, minimizes
variation from the set pressure, and ensures accurate operation.
● If subplate SHR02-02T1 is necessary, please order one separately.

RELIEF VALVE BALANCE PISTON TYPE（HR） SIZE 04
The balance piston type relief valve regulates the maximum pressure in the hydraulic circuit
to maintain the pressure in the circuit at a constant pressure.

■Features

1. The balance piston type design offers excellent pressure - flow characteristics, minimizes
variation from the set pressure, and ensures accurate operation.
2. The valve allows configuration of an unload circuit by using a vent port (VE). It also enables
remote control of pressure by connecting a pilot relief valve.
● If subplate SHR04-**T* is necessary, please order one separately.
