This Williams Controls 111817 is a heavy-duty WM219 series valve featuring a two-position, three-way "flipper" design that provides 15 SCFM of flow at 100 PSI. Unlike lighter plastic alternatives, this valve is built with a rugged die-cast zinc alloy body and a metal control lever to withstand the constant use and vibration of vocational truck cabs. The bottom-inlet configuration and compact 1/8" NPT ports allow for seamless panel mounting in tight dashboards, while the dedicated 1/16" exhaust port ensures the system vents quickly and completely when switched off.
