Brass Steam Solenoid Valve 3/8 in

The Dayton 4A702 is a two-way, normally closed brass valve body designed for steam and water control in plumbing and industrial systems. It suits maintenance engineers and facility managers who need a durable, lead-containing component rated for high-temperature fluid service.

Check pipe thread size and pressure rating

Verify that your piping uses a 3/8 in nominal connection and that the system pressure differential stays between 5 psi minimum and 150 psi maximum for water service. The valve body requires a separate coil matched to your voltage and enclosure rating before it can operate.

Valve body sold without coil

The package contains only the brass body with a 1/2 in orifice and 3.5 Cv flow coefficient; no solenoid coil, connector or mounting hardware is included. You must source a compatible coil separately to complete the assembly. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

Does the Dayton 4A702 valve body include the solenoid coil, or must that be purchased separately?

The supplier title states "Less Coil", so the brass body ships without a solenoid coil; a compatible coil must be sourced separately.

Which operating pressure rating should I use when selecting this 3/8 in valve for a water line?

For water service the maximum operating pressure differential is 150 psi, with a minimum of 5 psi required to actuate the normally closed valve.

What does the Cv 3.5 figure mean for flow through this 3/8 in brass valve in practice?

A Cv of 3.5 indicates the valve will pass 3.5 US gallons per minute of water with a 1 psi pressure drop across the 1/2 in orifice.
