Pressure control valves

 

Relief valve

HR*

■FEATURES
The balancing piston type design offers excellent pressure - flow characteristics, minimizes variation from the set pressure, and ensures accurate operation.
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.

Pilot-operated relief valve

HT3

■FEATURES
The pilot-operated relief valve is mainly used for remote control of the main circuit pressure by connecting it to the vent port (VE) of a balancing piston type relief valve. In a small-flow circuit, this type of valve can also be used as a direct acting type relief valve.

Solenoid-operated relief valve

HRD3

■FEATURES
1. Since an oil-immersed solenoid is used the plunger operates in the fluid, alleviating knocking sounds and ensuring quiet valve operation.
2. External oil leakage is eliminated, even after a long time in use, since the valve has no sliding seal parts.
3. Wiring work is simplified.
4. Dust- and water-proof levels are IP65 in accordance with IEC standards.
5. A grounding terminal is standard (AC only).
6. Permissible back pressure considerably increased.
7. A shockless valve that reduces the surge pressure generated at unloading is standard.
8. Surge killer is standard.
9. CE compatible product

Unload relief valve

HRU3

■FEATURES
This type of valve consists of a balancing piston type unloading valve and a check valve assembled in one housing and is mainly used in accumulator circuits and circuits in which two levels of pressure (low-pressure large-volume circuit and high-pressure small-volume circuit) are handled.

Pressure reducing valve

HG*

■FEATURES
1. This valve allows the setting of a low pressure and stably maintains this pressure at the set level.
2. The direct acting type valve ens ures a quick response and generates virtually no surge pressure.

Sequence valve, unload valve

HQ*、HU*

■FEATURES
This type of valve is used to control the operating sequence of the hydraulic circuit (sequence operation) or to relieve the pump pressure from the loaded state to the unloaded state (unloading operation).

Sequence valve with check valve, Counter balance valve

HQ*、HB*

■FEATURES
These valves are used to control the operating sequence of the hydraulic circuit (sequence operation) by controlling the pilot pressure, to hold the load, or to prevent a device from falling under its own weight (counterbalance operation).

Brake valve

HR-HKT*、HR-HKG*

■FEATURES
1. One brake valve unit can apply a brake in both the acceleration and deceleration stages.
2. The braking performance can be adjusted by adjusting the setting pressure.

Balancing valve

HGR2

■FEATURES
1. Using this type of valve, the hydraulic system can be designed compactly and installation space can be reduced.
2. The pressure can be adjusted easily with a single handle operation.
3. The valve is compact and light.
