The WV alternating valve is a self-acting hydraulic valve that automatically directs fluid from the higher-pressure inlet of two inlets to a single outlet, while the unpressurized inlet is sealed by a movable steel ball. These valves are used in hydraulic systems to automatically switch pressure lines, prevent backflow, and ensure safe and efficient operation in applications such as machine control systems and test benches. They are suitable for pressures up to 160 bar and operate over a temperature range of approximately -40°C to +120°C.
This valve operates without external control and functions as a self-acting switch. Fluid pressure from one of the two inlets forces the steel ball to move, sealing the unpressurized inlet. The high-pressure inlet connects to the single outlet, allowing fluid flow to control components or circuits. The steel ball provides a metal-to-metal seal, ensuring a secure closure of the unpressurized inlet and preventing backflow.
