Below is a list of Solenoid Valves manufacturers from Murray Hill, New Jersey. Solenoid valves are electromechanical valves that are used to control the flow of liquids or gases. Consisting of a solenoid coil and a valve, solenoid valves function by converting electrical energy into mechanical energy, which can open or close the valve in order to shut off, dose, release, mix or distribute the fluids or gases.
