Brass Solenoid Valve Trap 1 1/4 in

The Dayton 1A580 is a brass solenoid valve trap designed for drain and trap applications. It features a 1 1/4 inch nominal pipe size with a 2-way, normally closed configuration and a 16 Cv flow coefficient. The valve body is rated for a maximum fluid temperature of 180 Degrees F.

Suits indoor or outdoor drain lines needing 250

This valve suits plumbing systems requiring a normally closed solenoid for air, inert gas, or water service up to 250 psi differential pressure. It is not for buyers who need an integrated coil or a lower minimum operating pressure differential than 5 psi. The Proposition 65 warning applies for California installations.

Verify pipe size, pressure range

Before ordering, confirm your system uses 1 1/4 inch piping and operates within the 5 to 250 psi differential range. Ensure the fluid temperature does not exceed 180 Degrees F. Check that your separate coil matches the valve body specifications for voltage and environmental rating.

Questions about this item

What size pipe and coil voltage do I need to match this 1 1/4 in normally-closed brass body?

The valve body has a 1 1/4 in nominal pipe size and 1 1/4 in orifice; it is sold without a coil, so you must supply a compatible 2-way solenoid coil separately.

Will the 5 psi minimum pressure differential work with my existing low-pressure air line?

The valve requires at least 5 psi differential to open and handles up to 250 psi for air, inert gas or water, so your line must stay above 5 psi during operation.

How can I verify the 16 Cv flow rating is achieved after installation?

With the correct coil energised, measure flow at your operating pressure; a 16 Cv rating means 16 US gallons per minute of water at 1 psi pressure drop across the 1 1/4 in orifice.
