Red Hat 8030G017 120V AC Brass Solenoid Valve 1/2 in 15 psi 2.8 Cv

SKU CH-H4RN-KJ1NQ MPN 8030G017

A 120V AC brass solenoid valve with a 1/2 in pipe size, 2.8 Cv flow coefficient and 15 psi maximum pressure differential for air and inert gas

  • Product typeDrain Components
  • Normally closed design prevents flow until energised
  • 120V AC coil suits standard mains voltage
  • Brass body with NBR seal resists corrosion
  • 1/2 in NPT port fits common piping
  • 8 Cv at 15 psi delivers rated capacity

1/2 in Brass Solenoid Valve for 120V AC Systems

The Red Hat 8030G017 is a compact two-way solenoid valve built for 120V AC supply. Its brass body and NBR seals handle air or inert gas in normally closed drain and trap installations. The 1/2 in nominal pipe size and 7/16 in orifice suit standard plumbing connections. Operators needing reliable on-off control for low-pressure media will find this valve matches the spec.

Replaces Worn 2-Way Drain Valves at 15 psi Max

This unit serves as a direct replacement for failed compact solenoid valves in existing drain or trap circuits rated to 15 psi maximum differential. The jump is worth it when the old coil enclosure lacks a watertight seal or when the Cv has drifted below 2.8. It is not for fuel gas, fuel oil or systems exceeding the stated pressure limit.

Watertight Coil Holds 2.8 Cv Under Continuous 120V

The coil enclosure without a junction box maintains a watertight barrier during sustained energisation. Brass construction resists corrosion while the NBR seal preserves shut-off integrity over long cycles. Flow remains steady at the rated 2.8 Cv without the pressure drop spikes seen in burst-only testing. The valve stays closed when de-energised, preventing unintended discharge.

Questions about this item

What pipe size does the 1/2 in solenoid valve require for installation?

The valve connects to a 1/2 in nominal pipe size with a 7/16 in orifice diameter for proper flow alignment.

How do I wire the 120V AC coil without a junction box, and what common mistake should I avoid?

Connect the coil leads directly to a 120V AC supply using watertight connectors; the error is skipping sealant on the coil enclosure threads.

When should I replace the NBR seals on this 2.8 Cv brass valve?

Inspect the NBR seals annually and replace them if they show cracking, hardening, or if leakage appears at 15 psi differential.
