Brass Solenoid Valve 1/2 in

The Dayton 3A434 is a two-way, normally-closed brass valve body designed for drain and trap installations. It suits plumbers and facility managers who need reliable on-off control of water or inert gas lines.

Verify pipe size and pressure range

Confirm the existing line uses a 1/2 in nominal pipe connection and that system pressure stays within the 0 to 100 psi differential rating. The body is rated for fluid temperatures up to 180 Degrees F and carries a Cv of 3.6 for flow calculations.

Replaces worn valve bodies in drain systems

This unit upgrades from leaking or corroded brass bodies in existing solenoid assemblies. The step is worthwhile when the coil remains serviceable but the body shows wear, restoring positive shut-off without replacing the entire actuator.

Questions about this item

What comes with the 3A434 valve body and what must be purchased separately?

The 3A434 brass valve body is supplied without a coil; a compatible solenoid coil must be bought separately to complete the assembly.

Which operating pressure rating should I use when selecting this 1/2 in valve for water service?

For water applications the maximum operating pressure differential is 100 psi, with a minimum of 0 psi and a Cv of 3.6.

What does the 180 °F fluid-temperature limit mean for a hot-water system using this valve?

The valve can handle fluid temperatures up to 180 °F, so it is suitable for typical residential hot-water loops but not for steam or higher-temperature processes.
