Industrial Steam Control Valve
The ASCO 8222G074 is a pilot-operated solenoid valve designed for steam service in industrial plumbing systems. It operates in a normally closed, two-way configuration with a brass Y-shaped diaphragm body and PTFE seals. The unit includes the coil and 18-inch leads for 120V AC power at 50 Hz or 60 Hz frequencies. It suits maintenance teams and OEMs needing reliable high-temperature fluid control.
Brass Body With Conduit Connection
The valve installs via 3/8 inch NPTF inlet and outlet threads, fitting directly into compatible piping without adapters. Electrical supply enters through a 1/2 inch conduit fitting, simplifying wiring in panel or junction-box installations. Ambient temperature tolerance from 32°F to 125°F allows placement in typical mechanical rooms. The integrated coil removes the need for separate actuator mounting.
135 PSI Steam Differential Limit
The valve handles steam up to 353°F at a maximum differential pressure of 135 psi, with a minimum operating differential of 1 psi for water service. Pilot-operated action requires this pressure drop to shift reliably, so very low-pressure or vacuum lines are not suitable. California Proposition 65 warnings apply for chemical exposure. Systems exceeding the pressure or temperature ratings need a different valve class.

Questions about this item
How long will the PTFE diaphragm hold up at the 353 °F steam rating before it starts to degrade?
The PTFE seals and brass body are rated for continuous steam service up to 353 °F and 135 psi differential, so the diaphragm remains within its design limits under those conditions.
How hot does the coil get when the valve stays energised all day at 120 V AC?
The coil is designed for 120 V AC at 50 Hz and 60 Hz within a 32 °F to 125 °F ambient range; it will reach its normal operating temperature without exceeding the insulation class.
Do I need a separate 1/2 inch conduit fitting and 120 V AC supply to wire this valve?
Yes, the valve ships with 18-inch leads and requires a 1/2 inch conduit connection plus a 120 V AC circuit compatible with 50 Hz or 60 Hz.
