1/2 in Brass Solenoid Valve 120V AC

This Red Hat EF8210G094 is a normally closed, two-way valve designed for high-flow drainage applications. It suits installers who need reliable on-off control of air or inert gas lines in commercial or industrial plumbing systems. The brass body and NBR seals handle the specified media at pressures up to 150 psi. It is not intended for fuel gas or fuel oil service.

Installation notes and common issues

The valve features a 1/2 in nominal pipe size with a 5/8 in orifice for straightforward piping connections. Its explosion-proof, watertight coil enclosure requires appropriate fittings and conduit to maintain the rated protection. Wiring must match the 110V AC or 120V AC supply; incorrect voltage is the most frequent cause of coil failure. Ensure the flow direction arrow aligns with system design.

Practical limits of the interface

The 150 psi maximum operating pressure differential for air and inert gas defines the upper boundary for safe operation. Fuel gas and fuel oil service are not supported, so the valve cannot be used on those lines. The Cv of 4 indicates the flow capacity under standard test conditions. California Proposition 65 warnings apply due to chemicals present in the construction materials.

Questions about this item

How can I verify the EF8210G094 valve is operating correctly after installation?

Apply 120V AC and confirm the normally closed valve opens, allowing flow through the 1/2 in brass body; check for leaks at the NBR seals and ensure pressure differential does not exceed 150 psi for air or inert gas.

What components are included with the EF8210G094 and what must be sourced separately?

The valve body, explosion-proof watertight coil enclosure, and NBR seals are supplied; piping, fittings, thread sealant, and a 110V AC or 120V AC power source are not included.

Which voltage version of the EF8210G094 should I select for a standard US supply?

Choose the 120V AC rating; the coil also accepts 110V AC, but 120V AC matches typical North American mains voltage.
