Control Valves

In hydraulic systems, pressure control valves are employed to manage and regulate actuator force. This force is generated by a hydraulic actuator, which typically includes a cylinder or fluid motor that utilizes hydraulic power to enable mechanical operations. Additionally, these valves are utilized to specify and adjust pressure levels.

The primary roles of pressure control valves encompass;

  • Decreasing and relieving system pressure
  • Reducing pressure levels as the main circuit transfers to the sub-circuit
  • Managing system pressure within specific segments of the circuit.
  • Ensuring the maximum system pressure remains at a safe threshold.
  • Handling various pressure-related tasks associated with pressure control.
  • Facilitating the operational sequence of actuators in a circuit through pressure control.

Pressure-limiting Valves: These are a type of pressure control valves designed to protect the system from excessive pressures, while also restricting the operational pressure for specific system functions

Pressure-reducing Valves: These valves are another category of pressure control valves that maintain consistent pressure levels even when the inlet pressure varies.

Shut-off Valves: Responsible for receiving control oil from a high-pressure circuit, shut-off valves also divert the flow from a low-pressure pump to unpressurized circulation when the preset pressure value is reached.

Load-holding Valves: These valves prevent uncontrolled drops in loads on motors or cylinders. They come pre-loaded with a high-pressure setting that exceeds any potential load.

               The primary objective of pressure control valves is to enhance workplace safety by averting potential equipment damage caused by excessive pressure. This, in turn, safeguards workers and users of pressure equipment.
