This 2-way solenoid valve is pilot-acting. With a body constructed from stainless steel, and a stainless steel stem and viton diaphragms, its valves are normally closed (NC) and are internally piloted. The solenoid valve is ideal for use with water, air, beverage dispensing, lightweight oil, most chemical liquids and non flammable liquid gases. For ease of electrical connection, the 30mm coil connects with many options.
