  • TypeDrain Components
  • Brass body resists corrosion in plumbing systems
  • Slow-closing action reduces water hammer effects
  • Normally closed design stops flow when de-energised
  • 120V AC coil suits standard mains supply
  • Cv 3 rating handles moderate flow capacity

Brass Slow-Closing Solenoid Valve

The Red Hat 8221G013 is a 2-inch brass solenoid valve designed for drain and trap applications. It operates on 110V AC or 120V AC power and features a normally closed configuration. The slow-closing action helps prevent water hammer in piping systems. A watertight coil enclosure protects the electrical components.

Suitable for standard drain lines needing

This valve suits installations requiring a 2-inch nominal pipe size and a 1 3/4 inch orifice with a Cv of 3. The NBR seals handle air and inert gas service. It is not for fuel gas or fuel oil lines where maximum pressure differentials are not applicable. Buyers needing a junction box enclosure should look elsewhere.

2-inch nominal pipe size with 1 3/4 inch orifice

The 2-inch connection and 1 3/4 inch orifice determine flow capacity and pipe compatibility. A Cv of 3 defines the specific flow rate through the valve. Confirm these dimensions match the existing piping before purchase. The brass body and NBR seals dictate fluid compatibility.

Questions about this item

How is the 8221G013 installed and what step do people miss?

Thread the 2 in brass valve into the pipework, apply sealant to the NPT threads, then wire the coil to a 110V AC or 120V AC supply; the step often missed is confirming the arrow on the body matches the flow direction before tightening.

What maintenance or replacement will the 8221G013 need later?

The NBR seals and the slow-closing mechanism inside the 1 3/4 in orifice are the wear items; plan to inspect the diaphragm and replace the seal kit if leakage appears after extended cycling.

What limit appears first on the 8221G013 under sustained use?

Continuous energising of the 120V AC coil without a junction box can raise the enclosure temperature until the watertight seal degrades, so duty-cycle and ambient heat are the practical limits.
