Our pressure control valves keep hydraulic circuit pressure on an even keel.
We offer flow and pressure capabilities of 1-190 l/min [0.3-50 US gal/min] and up to 415 bar [6,000 psi], respectively.

Direct Acting Relief Valves
 |
| Direct Acting Relief Valves Example Schematic |
|
- Inlet pressure acts on the valve nose, providing pressure relief from the nose (1) to the side (2).
- Fast response to pressure spikes, with poppet design option for low leakage requirements.
- Flow range: 1.1-80 l/min [0.3-21 US gal/min].
- Pressure capability up to 415 bar [6,000 psi].
|
Differential Area Relief Valves
 |
| Differential Area Relief Valves Example Schematic |
|
- Inlet pressure acts on the valve nose, providing pressure relief from the nose (1) to the side (2).
- Available with integral free reverse flow check.
- Fast response to pressure spikes, with poppet design for low leakage requirements.
- Improved ability to handle higher flows with a lower pressure rise rate compared to direct acting relief valves.
- Flow range: 40-150 l/min [11-40 US gal/min].
- Pressure capability up to 350 bar [5,080 psi].
|
Pilot Operated Relief Valves
 |
| Pilot Operated Relief Valves Example Schematic |
|
- Inlet pressure acts on the valve nose, providing pressure relief from the nose (1) to the side (2).
- Stable design for pressure regulation.
- Low pressure rise rate for minimum horsepower losses when running at the relief setting for long periods.
- Flow range: 100-190 l/min [26-50 US gal/min].
- Pressure capability up to 350 bar [5,080 psi].
|
Bi-Directional Relief Valves
 |
| Bi-Directional Relief Valves Example Schematic |
|
- Pressure relief in both directions.
- Commonly used to replace two direct-acting valves, reducing system cost and complexity.
- Flow range: 40 l/min [11 US gal/min].
- Pressure capability up to 250 bar [3,600 psi].
|
Pressure Reducing Valves
 |
| Pressure Reducing Valves Example Schematic |
|
- Pressure reduction in part of the circuit with no impact on overall system pressure.
- Available as pressure reducing/relieving or pressure reducing valves.
- Choice of fast and economical direct acting version or pilot-operated version, which provides a smooth, stable. response, high pressure capability and precise control at varying flow rates.
- Flow range: 40-115 l/min [10-30 US gal/min].
- Pressure capability up to 350 bar [5,080 psi].
|
Sequence Valves
 |
| Sequence Valves Example Schematic |
|
- Pressure signal shifts the spool, opening or closing a flow path at a pre-set pressure.
- Used to control a sequence of operations for two or more actuators in a system.
- Many functional options available for a wide range of applications.
- Flow range: 4-150 l/min [1-39 US gal/min].
- Pressure capability up to 350 bar [5,080 psi].
|
Unloading Valves
 |
| Unloading Valves Example Schematic |
|
- Type of sequence valve that uses a remote pressure signal to unload a circuit.
- Commonly used for unloading an accumulator charging circuit or unloading a pump to tank at minimum pressure.
- Flow range: 4-160 l/min [1-42 US gal/min].
- Pressure capability up to 350 bar [5,080 psi].
