Proportional Valves

Proportional valves are electrically controlled hydraulic valves that regulate flow or pressure based on the strength of an input signal. They use proportional solenoids to vary the valve position, allowing precise, repeatable control across a continuous range rather than simple open/closed operation.

Key features include:  

• Variable electrical control – output changes proportionally to the input signal.

• Smooth, accurate modulation – ideal for applications requiring fine control.

• Multiple valve types – including proportional directional, pressure, and flow valves.

• Advanced electronics options – with or without integrated amplifiers or position feedback.

• High-performance construction – engineered for demanding mobile and industrial environments.

These capabilities make proportional valves essential for systems requiring precision, responsiveness, and efficiency.

• Precise actuator control – enables smooth acceleration, deceleration, and speed regulation.

• Improved efficiency – reduces energy waste by matching output to system demand.

• Enhanced machine performance – supports complex motion profiles and load‑sensitive operation.

• Flexible integration – compatible with modern electronic control systems.

• Reduced mechanical stress – smoother operation extends component life.

• Greater operator comfort – eliminates abrupt movements in mobile machinery.

Proportional valves are widely used in systems requiring fine, dynamic control, including:

• Mobile machinery (construction, agriculture, forestry)
• Industrial automation and process control
• Marine and offshore hydraulic systems
• Energy and utility installations
• Material handling and lifting equipment

Their ability to deliver smooth, responsive control makes them indispensable in advanced hydraulic circuits.

If you’re unsure which type best suits your system, our technical team can help you specify the correct valve based on flow, pressure, control requirements, and electronic interface.

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

Argo‑Hytos | Atlantic Fluid Tech | Bosch Rexroth | Danfoss | Eaton | Hawe | Hydac | 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 valves different from standard hydraulic valves? 
They provide smooth, variable control rather than simple on/off operation, enabling precise regulation of speed, pressure, and direction.

Do proportional valves require special electronics? 
Many models use external amplifiers or integrated electronics (OBE). We can help you match the correct control method to your system.

Are proportional valves suitable for mobile equipment? 
Yes. They are widely used in mobile machinery where smooth, responsive control is essential.
