The DRVP6-40 Type Restrictor Valve / Check Restrictor Valve is a compact hydraulic flow control valve designed for precise adjustment of oil flow and actuator speed control in hydraulic systems. Featuring an integrated check valve function, the valve allows controlled flow in one direction and free return flow in the opposite direction. It is widely used in hydraulic power units, industrial machinery, construction equipment, and mobile hydraulic systems.

Working Principle

The DRVP6-40 check restrictor valve combines a throttle valve and a check valve in one compact unit. The adjustable throttle section controls the oil flow in one direction by changing the flow cross-section through the adjustment spindle. In the reverse direction, the built-in check valve opens automatically, allowing hydraulic oil to flow back freely with minimal resistance.

The valve is especially suitable for:

• Cylinder speed regulation
• Hydraulic motion damping
• Controlled actuator movement
• Hydraulic circuit flow adjustment
