The WM639 is an in-line shuttle valve engineered for applications with a low to moderate air flow rate. It functions as a double check valve, allowing two pressure sources to independently supply a single outlet. The WM639 is equipped with a die cast zinc shuttle which moves freely back and forth in a chamber connecting the valve’s two inlet ports. As long as there is a pressure differential between the inlets, the shuttle seals off the one with the least supply pressure. This valve in commonly used in air brake systems in which a hand valve and a treadle are both used to control the same function. Part Number: 113934 Manufactured by Williams Controls.
