Dayton coil-less solenoid valves are 2-way valves that electrically control the release of air, water, inert gas & light oil in water treatment systems, humidifiers, vending machines and welding equipment. These valves have brass construction with Buna N gaskets for resistance against oils, gasoline & petroleum-based fluids and are capable of withstanding fluid temperatures up to 180 degrees F. These normally closed valves feature direct-acting or pilot operation for opening and closing of the valves. Choose from a wide range of these solenoid valves to fit pipe sizes of 1/8, 1/4, 3/8 and 1/2 inches.
