USE AND OPERATION: These valves are used to adjust speed of actuators in one direction; flow is free in the reverse. Internal pressure compensation allows constant speed even with varying loads. These valves are characterised by a high adjustment accuracy. MATERIALS AND FEATURES: Body: zinc-plated steel. Internal parts: hardened and ground steel. Seal: BUNA N standard. Leakage control - needle type. Minimal leakage when the valve is closed. CONNECTIONS: Connect V to the supply and C to the actuator to control; flow is adjust from C to V and is free in the reverse direction. Flow adjustment is done by rotating the plastic hand knob after loosening the side locking screw. This particular configuration allows an accurate adjustment.
