  • TypeDrain Components
  • MaterialHAWA
  • Normally closed design prevents steam loss when de-energised
  • Brass body resists corrosion in high-temperature steam service

  • 6 Cv rating delivers strong flow for 1/2 in piping
  • Watertight coil enclosure protects 110/120V AC winding from moisture

Brass Steam Solenoid Valve 1/2 in

This 1/2 in brass solenoid valve controls steam flow in industrial and commercial systems. It operates on 110V AC or 120V AC power with a normally closed configuration. The PTFE seal and watertight coil enclosure suit high-temperature service. The valve provides a Cv of 3.6 for steam applications.

Not for low-pressure air or fuel systems

The valve carries no rated maximum pressure differential for air or inert gas. Fuel gas and fuel oil maximums are listed as not applicable. Buyers needing rated pressure limits for those media should select a different valve. California Proposition 65 warnings also apply for cancer and reproductive harm.

120V AC normally closed steam service

The coil voltage of 120V AC and normally closed starting position define the control logic. This combination suits automated steam shut-off where power loss closes the valve. Verify the supply voltage matches 110V AC or 120V AC before installation.

Questions about this item

What pipe size and orifice diameter does the 8222G047 require for mounting?

The valve uses a 1/2 in nominal pipe size and a matching 1/2 in orifice, so the piping and flange must accommodate that exact diameter.

How is the 120V AC coil wired during installation, and what step is often missed?

Connect the coil leads to a 110–120V AC supply; the step often missed is verifying the coil enclosure remains watertight after wiring to maintain the seal.

Which component will need periodic replacement in steam service?

The PTFE seal is the wear item that will require inspection and eventual replacement as it ages under high-temperature steam cycles.
