SKU CH-23TB-YCECX MPN 3A430

A normally-open stainless-steel solenoid valve body with a 1/4-inch port, 3/32-inch orifice and Cv of .17 or .22 handles air, inert gas or water up to 75 psi and 180 °F

  • TypeDrain Components
  • Stainless steel body resists corrosion in harsh environments
  • Normally open 3-way design enables automatic flow control
  • 1/4 in NPT port fits standard plumbing connections
  • Operates up to 75 psi for air, gas, or water service
  • Handles fluid temperatures up to 180 °F

Product Identity

The Dayton 3A430 is a stainless steel solenoid valve body designed for fluid control in plumbing and industrial systems. It suits engineers and maintenance teams who need a corrosion-resistant, three-way valve for air, inert gas or water lines. Buyers requiring an integrated coil or a different pipe diameter should look elsewhere.

Critical Specification

The valve has a 1/4 inch nominal pipe size and a 3/32 inch orifice delivering Cv values of .17 and .22. It operates from 0 psi up to a maximum of 75 psi for both air and water with a fluid temperature limit of 180 Degrees F. This pressure and temperature envelope is the deciding factor for system compatibility.

Accessory Impact

The unit is supplied less coil, so a compatible coil must be sourced separately to complete the assembly. The normally open, two-position, three-way body configuration directs flow until the coil is energised, enabling automated control in corrosive indoor or outdoor environments.

Questions about this item

What flow rate does the 0.17 Cv coefficient deliver in a live system?

The 0.17 Cv rating means the valve passes 0.17 US gallons per minute of water with a 1 psi pressure drop across the 3/32 in orifice.

How does the 1/4 in NPT connection limit the maximum working pressure?

The stainless steel body is rated for 75 psi differential on air, inert gas or water regardless of the 1/4 in pipe thread size.

What clearance is needed to mount the 3A430 body without the coil?

The valve body alone fits a 1/4 in NPT port; allow extra depth for the separate coil that threads onto the solenoid stem.
