Williams 111231 WM80 3/8in Shuttle Valve

The WM80 is a bracket-mounted shuttle valve engineered for applications which operate with a moderate air flow rate. It functions as a double check valve, allowing two pressure sources to independently supply a single outlet. As long as there is a pressure differential between the two inlets, the shuttle seals off the one with the lease pressure. WM80 valves are available with the option of an additional port for installation of a pressure gage or switch. This shuttle valve is commonly used in air brake systems where a hand valve and a treadle are both used to control the same function.
