Brass Solenoid Valve 3/4 in Normally Closed

The Dayton 3A437 is a two-way brass solenoid valve body designed for plumbing drain and trap applications. It accepts a 3/4 inch nominal pipe size and operates in a normally closed configuration. The valve suits installers who need a durable brass body for controlling water or inert gas flow in indoor or outdoor environments. It is not for buyers who require an integrated coil or a different pipe diameter.

Sustained pressure handling up to 250 psi

Under continuous operation the valve body withstands a maximum operating pressure differential of 250 psi for both air or inert gas and water service. The minimum operating pressure differential is 5 psi and the maximum fluid temperature is 180 degrees Fahrenheit. These ratings apply to steady-state conditions rather than momentary spikes. The component is not for systems that exceed these pressure or temperature limits.

3/4 inch orifice with Cv 7 flow capacity

The orifice diameter matches the 3/4 inch pipe size and provides a coefficient of volume (Cv) of 7, which determines the flow rate achievable through the valve. This single hydraulic parameter decides whether the valve can deliver the required volume for a given application. It is not for circuits that demand a higher or lower flow coefficient.

Questions about this item

How much heat can the brass body handle during continuous operation?

The valve body is rated for fluid temperatures up to 180 degrees F, so it will tolerate sustained hot-water service within that limit.

What coil voltage must I supply to actuate this 3/4-inch normally-closed valve?

The body is sold without a coil; you must provide a compatible Dayton coil that matches your control voltage and the 3/4-inch orifice.

Will the 7 Cv flow coefficient work with my existing 3/4-inch piping and standard municipal pressure?

Yes, the 7 Cv rating and 5 to 250 psi operating range suit typical 3/4-inch lines and normal supply pressures.
