Dayton 3A438 Brass Solenoid Valve 1 in Trap

SKU CH-MSPJ-VFPNA MPN 3A438

Brass solenoid valve body with 1 in orifice and 13 Cv flow capacity for air, inert gas or water up to 250 psi and 180 °F

  • TypeDrain Components
  • 1 in brass body resists corrosion
  • Cv 13 delivers high flow capacity
  • Normally closed design stops flow when de-energised
  • Rated to 250 psi for air and water
  • Operates up to 180 °F fluid temperature

Brass Solenoid Valve 1 in

The Dayton 3A438 is a two-way, normally closed solenoid valve body constructed from brass with a 1 in nominal pipe size and 1 in orifice diameter. It is intended for plumbing professionals and facility managers who need a durable drain component for controlling fluid flow in commercial or industrial piping systems.

Upgrade From Manual Or Worn Valves

This valve replaces manual shut-off valves or older solenoid bodies that leak, stick, or lack the 13 Cv flow capacity required for higher-volume lines. The jump is worth it when the application demands a 5 psi minimum operating pressure differential and up to 250 psi maximum for air, inert gas, or water service at fluid temperatures up to 180 Degrees F.

Suits Indoor And Outdoor Installations

The brass body and indoor/outdoor environmental rating make it suitable for technicians who need a reliable, normally closed configuration in exposed or protected locations. Buyers who require an integrated coil, a different pipe size, or a normally open starting configuration should look at other valve bodies.

Questions about this item

What pipe size does the 1 in brass valve body require?

The valve body has a 1 in nominal pipe size and a 1 in orifice diameter, so it fits standard 1 in piping.

How is the coil installed on this normally closed valve?

The valve ships less coil; mount the correct coil onto the brass body and wire it so energising the coil opens the normally closed 2-way valve.

When should the brass body or internal seals be replaced?

Replace the body or seals if leakage appears, if the valve no longer closes at the 5 psi minimum differential, or after prolonged exposure near the 180 °F fluid-temperature limit.
