Red Hat 8030G003 120V AC Brass Solenoid Valve 3/4 in

SKU CH-EVEA-J0SKN MPN 8030G003

120V AC brass solenoid valve with a 3/4 in orifice, normally closed for high-flow drain control

  • Product typeDrain Components
  • Main materialHAWA
  • 120V AC coil enables direct mains control
  • Normally closed design stops flow when de-energised
  • Brass body resists corrosion in fluid lines
  • 3/4 in pipe size matches standard fittings
  • Watertight coil enclosure protects against moisture ingress

Solenoid Valve for Fluid Control

The Red Hat 8030G003 is a 2-way, normally closed solenoid valve designed to manage flow in compatible piping systems. Its brass body and NBR seals suit air, inert gas and similar media in industrial or commercial installations. The watertight coil enclosure protects the 120V AC winding from moisture and splashing. This component fits professionals who need reliable on-off control in a 3/4 in line.

Maximum Pressure Differential 2 psi

The operating pressure differential for air and inert gas tops out at 2 psi, which is the single figure that decides whether the valve will open and close correctly in a given circuit. Fuel gas and fuel oil ratings are not applicable, so the valve must not be specified for those media. Exceeding the 2 psi limit risks seat leakage or failure to actuate, so system pressure must stay within this bound.

Watertight Coil and Brass Body

The watertight coil enclosure shields the 120V AC solenoid from water ingress, reducing downtime in wash-down or humid environments. Brass construction resists corrosion from the approved media, while the NBR seals maintain tight shut-off at the 3/4 in orifice. No additional fittings, wiring harnesses or software are supplied with the valve itself.

Questions about this item

What does a Cv of 5 mean for flow through this valve?

The Cv of 5 indicates the volume of water in US gallons per minute that will pass through the valve with a 1 psi pressure drop, so it defines the practical flow capacity for a 3/4 in line.

How does the 120V AC coil interface with the 2 psi air pressure limit?

The 120V AC watertight coil actuates the normally closed valve, but the maximum operating pressure differential for air or inert gas is capped at 2 psi regardless of voltage.

What pipe threading and clearance does the 3/4 in brass body need for mounting?

The valve has a 3/4 in nominal pipe size and orifice, so it requires matching 3/4 in NPT threads and enough space for the brass body and watertight coil enclosure.
