  • Operates up to 180 °F fluid temperature for hot-water lines

Brass Solenoid Valve 1/2 in Normally Closed

This Dayton brass solenoid valve body is a 2-way, 2-position normally closed unit with a 1/2 inch nominal pipe size and 1/2 inch orifice. It suits plumbing systems that need on/off control of water or inert gas. The brass body handles fluid temperatures up to 180 degrees F and carries a Cv of 3.5.

Installation and common issues

The valve body threads onto 1/2 inch pipe and requires a separate coil to operate. Leaks typically come from damaged threads or missing sealant on the pipe connections. Verify the coil voltage matches the supply before wiring. The minimum operating pressure differential is 5 psi.

Pressure and temperature limits

Maximum operating pressure differential is 250 psi for both air/inert gas and water service. Fluid temperature must not exceed 180 degrees F. These two ratings define whether the valve matches the system design. The body is rated for indoor and outdoor environments.

Questions about this item

How can I verify the valve is functioning correctly after installation?

Apply at least 5 psi differential across the 1/2 in brass body and confirm the normally closed 2-way valve opens fully; the Cv of 3.5 indicates expected flow capacity for air, inert gas or water up to 250 psi.

What components are included and what must be sourced separately?

The package contains the solenoid valve body only; a compatible coil must be purchased separately to actuate the normally closed 2-position mechanism.

Which pressure and temperature ratings should guide my selection of this 3A435 model?

Choose this valve when the system operates between 5 psi minimum and 250 psi maximum differential for air, inert gas or water, with fluid temperatures not exceeding 180 °F.
