2-way pilot operated solenoid valve

The Red Hat 8221G007HW is a 2-way, 2-position pilot operated solenoid valve with a normally closed, slow-closing design. It features a brass body with EPDM seals and includes a coil rated for 6.1 W at 120V AC. Connections are 1 in nominal pipe size with NPTF threading for inlet and outlet.

Plumbing and steam systems needing slow-closing

This valve suits installations that require pilot operated control of hot water up to 210°F or steam up to 344°F with a slow-closing action to reduce water hammer. The corrosion-resistant, watertight coil enclosure allows indoor or outdoor use. It is not for applications needing a normally open configuration, a junction box included, or media other than hot water and steam.

120V AC coil voltage with 6.1 W rating

The coil operates on 120V AC at both 50 Hz and 60 Hz with a power consumption of 6.1 W and Class F insulation. This voltage and wattage combination determines whether the valve can be driven by the available control circuit. Confirm the supply matches 120V AC before installation.

Questions about this item

How often will the EPDM seals need replacement with steam at 344°F?

EPDM seals are rated for continuous steam service up to 344°F; replacement interval depends on cycle frequency and water quality, but the material is chosen for long life in this temperature range.

What limits continuous operation when the valve cycles on 120V AC at 6.1 W?

The Class F coil insulation and 6.1 W rating set the thermal limit; sustained duty is permitted as long as ambient temperature and media temperature stay within the 210°F water / 344°F steam ratings.

How much heat does the 6.1 W coil add to the enclosure during all-day operation?

The coil dissipates 6.1 W continuously when energised; the corrosion-resistant, watertight enclosure is designed to dissipate this heat without exceeding Class F insulation limits.
