Brass solenoid valve body, 3/4 inch pipe, normally closed, less coil

Dayton

Dayton 1A578 Brass Solenoid Valve 3/4 in 5.5 Cv 125 psi

SKU CH-VTHT-Q86J2 MPN 1A578

A brass, normally-closed 2-way solenoid valve body for 3/4 in pipe with 5.5 Cv flow and 125 psi pressure rating, coil not included

  • TypeDrain Components
  • Normally closed design prevents unwanted flow
  • Brass body resists corrosion in water systems
  • 5 Cv rating handles high-volume applications
  • 125 psi rating suits standard pressure lines
  • 180 °F max temperature supports hot fluids

3/4 in Brass Solenoid Valve Body

This 3/4 in brass solenoid valve body is a normally closed, two-way component rated for up to 125 psi with air, inert gas or water. It carries a Cv of 5.5 and a maximum fluid temperature of 180 Degrees F, making it suitable for plumbing and industrial drain installations. The body is sold without a coil, so a compatible coil must be sourced separately. It is rated for both indoor and outdoor use.

Installers needing a direct-acting brass valve

Plumbers and maintenance technicians who require a 3/4 in normally closed brass valve for drain or trap lines will find this body matches the pressure and temperature specs. Buyers who need a complete, ready-to-install assembly with coil and connector included should look elsewhere, as this listing supplies the valve body only. Systems demanding a different pipe size, orifice or flow coefficient are not served by this model.

Valve body supplied less coil

The package contains the brass valve body alone; no coil, wiring harness or mounting hardware is bundled. This means the installer must select and fit a coil that matches the required voltage and electrical connection. The absence of a coil allows flexibility for AC or DC control circuits but adds a procurement step before the valve can be commissioned.

Questions about this item

What coil voltage must I supply to operate the 1A578 valve body?

The 1A578 is sold as a less-coil body; you must purchase a compatible Dayton coil that matches your control voltage and install it before the valve will actuate.

Will the 5.5 Cv brass body handle the same 125 psi water line that my older 1/2 in valve used?

Yes, the 1A578 is rated for 125 psi maximum operating pressure differential with water, so it can replace the older valve provided the pipe size is adapted to 3/4 in.

How can I verify the 1A578 is opening and closing correctly after installation?

Apply the rated coil voltage and confirm fluid flows when energised and stops when de-energised; the normally closed design should show zero leakage at up to 125 psi when the coil is off.
