Hydraulic Flow Control Valves

Hydraulic flow control valves are used to regulate the rate of flow of fluid in a hydraulic pipeline or system. Flow control valves ensure that the speed and pressure of the fluid in the system is maintained at all times, essential for system performance. Hydraulic flow control valves are used to control the flow to cylinders pumps and motors. RS Components offer a range of high-quality hydraulic valves from leading brands including Parker, Bosch Rexroth, Enerpac, Hi-Force and of course RS PRO.

Single Acting or Double Acting Valves?

Single-acting flow control valves allow you to control the flow in one direction and free flow in the opposite direction. Double-acting flow control valves allow flow control in both directions.

Line Mounting Hydraulic Control Valves

Line mounting hydraulic valves as the name suggests are control valves that are mounted directly in a hydraulic pipeline. These types of control valve an inlet and an outlet port and an adjustable rotary actuator for adjusting fluid flow in a hydraulic circuit. Line mounting control valves are typically constructed from steel, carbon steel or nickel-plated brass. In-line control valves have a female threaded connection at each end for quick and easy connection. Thread standards include BSP ports and NPT ports in sizes ranging from 1/8 inch to 1 inch.

What is CETOP?

CETOP stands for Comit&eacute Européen des Transmissions Oléohydrauliques et Pneumatiques. CETOP is the European Fluid Power Committee. CETOP is the communications platform for fluid power in Europe. CETOP mounting valves have a standard mounting pattern for modular construction. It ensures that any valves from any manufacturer, providing the CETOP pattern is the same is compatible with each other.
