Direct Operated 3 Port Solenoid Valves are used as integral parts of water, air, gas and oil transferring pipelines. These are perfect options for flow controlling of fluids and air. Usually, these valves have ¼ inch port size and their orifice diameter ranges between 1.2 mm to 5 mm. Equipped with piston or diaphragm, these valves can be operated at -5 degree C to 80 degree C temperature range. Normally closed design, accessibility in different threading specifications and long working life are the key aspects of these valves.
