It provides manual open/close control of air, fuel, coolant, or other fluids in commercial vehicle systems. The forged brass body and Teflon seats ensure leak-tight shutoff and long life. It is commonly used in air suspension, brake accessory, and auxiliary circuits where isolation is needed for service or to shut off air supply. Replace the valve if it becomes hard to turn, leaks, or seizes.
