Brass Solenoid Valve 3/8 in

The Dayton 1A576 is a normally closed two-way brass solenoid valve body designed for drain and trap applications. It accepts a 3/8 inch pipe connection and operates without an included coil. This component suits plumbing systems that require reliable on-off control of air, inert gas, or water flow.

Pressure Limits 150 psi

The valve handles a maximum operating pressure differential of 150 psi for both air or inert gas and water service. A minimum differential of 5 psi is required for proper actuation. Fluid temperature must not exceed 180 degrees Fahrenheit. The brass body carries a Cv factor of 2.8 and is rated for indoor or outdoor environments.

Installation Notes

The valve body is sold less coil, so a compatible coil must be sourced separately before the assembly will function. Ensure the piping orientation matches the 2-way flow path and that the pressure differential in the system meets the 5 psi minimum. California Proposition 65 warnings apply because the brass contains chemicals known to cause cancer and reproductive harm.

Questions about this item

How do I pick between the 3/8 inch and other pipe sizes for this Dayton solenoid valve?

This model 1A576 is offered with a 3/8 in nominal pipe size and a 5/8 in orifice. Other sizes are separate part numbers; match the pipe thread on your existing line.

What does the Cv of 2.8 mean once the valve is installed in my system?

A Cv of 2.8 indicates the flow capacity: roughly 2.8 US gallons per minute of water at a 1 psi pressure drop across the valve.

How does the 150 psi pressure rating limit what fluids I can run through this brass valve?

The valve handles air, inert gas or water up to 150 psi differential, with a minimum 5 psi to operate, and fluid temperatures up to 180 °F.
