Proportional Cartridge Relief Valves

These valves are a type of cartridge valve that combine relief functionality with proportional control.

Key features include:

• Proportional actuation – enables smooth, variable regulation of pressure.

• Automatic system protection – prevents overload by relieving excess pressure.

• Compact cartridge format – fits directly into hydraulic manifolds for space-saving installation.

• Durable construction – engineered for continuous use in demanding environments.

• Versatile configurations – available in multiple sizes, flow capacities, and pressure ratings.

• Precise regulation – ensures accurate control of system pressure.

• Enhanced efficiency – proportional actuation reduces energy waste and improves responsiveness.

• Reliable protection – safeguards pumps, motors, and actuators from overload.

• Space-saving design – compact cartridge format simplifies installation.

• Extended equipment life – reduces wear and mechanical stress on components.

These valves are widely used in industries and applications including:

• Construction and agricultural machinery

• Industrial automation and process control

• Marine and offshore hydraulic systems

• Mining and heavy industry equipment

• Energy and utility installations

They are particularly valuable in systems where precise, proportional pressure regulation is required for safety and efficiency.

We source proportional cartridge relief valves from a wide network of manufacturers, including:

• Atlantic Fluid Tech – proportional cartridge technologies

• Wandfluh and more.

As an independent supplier, we provide unbiased recommendations based on your system’s needs – not a manufacturer’s catalogue.

What makes proportional relief valves different from standard relief valves? They allow smooth, variable regulation of pressure rather than fixed-threshold operation.

Can proportional cartridge relief valves be used in mobile equipment? Yes, they are widely used in mobile and agricultural machinery where precise pressure control is essential.

Do these valves require much maintenance? Minimal – their robust cartridge design ensures long service life with straightforward upkeep.
