Brass Solenoid Valve 1 in N/C

The Dayton 1A579 is a two-way brass solenoid valve body designed for drain and trap installations. It ships without a coil and uses a normally closed configuration with a one-inch nominal pipe size and one-inch orifice diameter. The Cv rating is 13.

125 psi Maximum Pressure Differential

This valve handles air, inert gas, and water up to 125 psi differential pressure with a minimum of 5 psi required to operate. Maximum fluid temperature is 180 degrees Fahrenheit and the brass body is rated for indoor or outdoor use.

Suits Drain Systems Needing 1 in Normally Closed

Installers who need a one-inch normally closed brass body for drain or trap lines will find the pressure and temperature ratings match common commercial requirements. Buyers who want a complete assembly with coil included or who require a different pipe size or normally open action should look at something else.

Questions about this item

How much flow does a Cv of 13 actually give when the valve is installed?

A Cv of 13 means the valve passes 13 US gallons per minute of water with a 1 psi pressure drop across the body.

What does the 125 psi rating limit in a compressed-air or water system?

The 125 psi maximum operating pressure differential caps the highest inlet-to-outlet pressure the valve can handle for both air and water service.

What pipe threads and clearance are needed to mount this 1-inch brass body?

The valve has 1-inch nominal pipe threads on both ports and a 1-inch orifice, so it fits standard 1-inch NPT piping with enough wrench room for the brass body.
