The two-way, two-position, normally open or normally closed, pilot-diaphragm-operated Series 4700 solenoid valves are designed for high-flow, high-pressure applications such as condensation removal, car washes, autoclaves, and irrigation control. These valves have orifice sizes of 20 to 25 mm, port sizes of ¾ and 1.0-in. NPT, and are offered with a standard manual override. Depending on port size, the valve operates at 4.5 to 220-psi and has a flow factor of 9.1 to 14 Cv. The encapsulated coil is a quick-connect DIN 43650 Form “A” design that is compatible with air, oil, gas, water, and fuel. Operating temperature range is –15 to 50°C.
