Brass 1/2 inch normally closed steam solenoid valve body without coil

Dayton

Dayton 1A582 Brass Steam Solenoid Valve 1/2 in Normally Closed Less Coil

SKU CH-YQ1R-NRR53 MPN 1A582

Brass 1/2-inch normally-closed solenoid valve body rated for 100 psi air or water and 250 °F fluid temperature, supplied without coil

  • TypeDrain Components
  • Brass body resists corrosion in steam service
  • Normally closed design stops flow when de-energised
  • 6 Cv rating supports high-capacity steam lines
  • Rated to 250 °F for saturated steam applications
  • 1/2 in NPT fits standard piping systems

Brass Steam Solenoid Valve 1/2 in

The Dayton 1A582 is a two-way, normally closed brass valve body designed for steam and fluid control in plumbing and industrial systems. It operates without a coil, allowing the installer to select a compatible actuator for the specific voltage and application. The 1/2 inch nominal pipe size suits standard piping.

Suits steam and fluid control up to 250 Degrees F

This valve suits engineers and maintenance teams needing a durable brass body for steam, water or inert gas lines with a 3.6 Cv flow coefficient. It handles a maximum pressure differential of 100 psi for air, gas or water. Buyers who require a complete assembled valve with coil included should look at a different product.

3.6 Cv flow and 100 psi pressure headroom

The 5/8 inch orifice and 3.6 Cv rating provide capacity for moderate steam or liquid flow in 1/2 inch pipework. It operates from 0 psi minimum differential up to the 100 psi limit across supported media. The 250 Degrees F fluid temperature maximum sets the upper boundary for steam applications.

Questions about this item

What coil voltage and enclosure rating must I supply for this normally closed 1/2 in brass valve?

Choose a coil that matches your control voltage and carries the same pressure rating; the body is rated for 100 psi air or water and 250 °F fluid temperature.

Will the 5/8 in orifice and 3.6 Cv handle the same flow as my existing 1/2 in steam line?

The 5/8 in orifice and 3.6 Cv provide higher capacity than a standard 1/2 in port, so it will not restrict flow in an existing 1/2 in steam line.

How can I verify the valve opens and closes correctly after wiring the coil?

Apply control voltage and listen for the click; then confirm steam passes when energised and stops when de-energised, with no leakage at 100 psi.
