Pilot-operated steam valve

The Red Hat 8222G049 is a 2-way, normally closed solenoid valve designed for steam flow control. Its brass body and PTFE seals handle fluid temperatures up to 353°F and ambient conditions from 32°F to 125°F. The 120V AC coil enables automation-capable control via external signals for industrial or commercial systems.

Installation and common issues

The valve connects via 3/4 in NPTF inlet and outlet ports using standard pipe thread sealant. A Y-shape diaphragm design with a 1/2 in orifice requires clean steam supply to prevent pilot port blockage. Ensure the coil orientation matches the enclosure rating and verify voltage before energising to avoid coil failure.

Pre-order system checks

Confirm your piping provides the 3/4 in NPTF connections and that system pressure suits pilot-operated operation. Verify the electrical supply delivers 120V AC compatible with the coil specification. Check that ambient and steam temperatures remain within the 32°F to 125°F and 353°F limits respectively. Ensure California Proposition 65 compliance requirements are met for your installation location.

Questions about this item

How can I confirm the valve is operating correctly after installation?

Verify steam flow stops when the 120V AC coil is de-energised and resumes when energised; the normally closed design should block flow without power and open with it.

What comes in the box and what must be purchased separately?

The valve body with brass construction, PTFE seals and 3/4 in NPTF ports is supplied; piping, thread sealant and a 120V AC power source are not included.

Which configuration suits a steam line needing automatic on/off control?

The 2-way, 2-position, normally closed, pilot-operated design with 1/2 in orifice and 3/4 in pipe size is built for automated steam flow control up to 353°F.
