Hydraulic valves

Explore hydraulic valves by circuit function: preventing reverse flow, regulating flow, limiting pressure, controlling loads and dividing flow. This catalogue focuses on model data and primary technical references.

Choose a valve function

• Check valves for one-way flow control.
• Flow control valves for flow adjustment and pressure-compensated control.
• Pressure relief valves for pressure-limiting functions.
• Overcenter valves for the documented single-acting, double-acting and balanced designs.
• Electrically operated hydraulic valves for electrical actuation and related model families.
• Flow dividers for the documented flow-division arrangements.

How to select

First identify the required hydraulic function and inspect the circuit symbol. Compare flow capacity, maximum pressure, port connections and adjustment range as separate specifications. A valve setting or adjustment limit is a different parameter from its maximum pressure rating.

For piloted valves, read the pilot ratio in the convention used by the source catalogue. Match the exact model and product revision when checking installation dimensions or replacement compatibility.
