Solenoid Valve, 2-Way, 2-Position, Normally Closed, 1/2 in Pipe Size, 120V AC, Diaphragm, Piston

The ASCO SU8220G406 is a 2-way, 2-position pilot-operated solenoid valve with a normally closed starting configuration. It features a brass body and diaphragm valve design, constructed to control the flow of hot water and steam. This valve operates with an included coil at 120V AC and ambient temperature range: 14°F to 140°F. Media temperature ratings: hot water up to 210°F; steam up to 353°F, maximum differential pressures: hot water 150 psi; steam 125 psi; light oil 210 psi; air/inert gas 150 psi. The valve utilizes NPTF inlet and outlet connections with a nominal pipe size of 1/2 inch, and a 1/2 inch orifice diameter. Electrical connections: DIN interface; enclosure: watertight; junction box not included.
