  • 300 psi rating handles high-pressure air, gas or water
  • 180 °F fluid limit suits hot-water applications

Product Identity

The Dayton 3A423 is a 1/8 in stainless steel solenoid valve body designed for fluid control in plumbing and industrial systems. It suits engineers and maintenance teams needing a normally closed, two-way valve for air, inert gas or water lines.

Installation Checks

Verify that your piping uses a 1/8 in nominal connection and that system pressure stays within the 0 to 300 psi differential range for air, inert gas or water. Confirm the fluid temperature will not exceed 180 Degrees F and that the environment matches the corrosive, indoor and outdoor rating. Note that the coil is not included and must be sourced separately.

Sustained Operation

The stainless steel body resists corrosion during continuous exposure to harsh fluids and environments. With a Cv of .22 and a 3/32 in orifice, the valve maintains consistent flow control under steady pressure differentials up to 300 psi. The normally closed configuration holds shut reliably during extended energised or de-energised periods.

Questions about this item

What is included with the valve body and what must be purchased separately?

The package contains the stainless steel solenoid valve body only; a compatible coil must be bought separately to operate the valve.

Which version should I select for a 1/8 in line with a 3/32 in orifice and a Cv of .22?

This single model 3A423 matches those exact specifications, so no alternative version or capacity choice is needed.

How does the 300 psi maximum pressure differential perform in an actual air or water system?

The valve handles up to 300 psi differential for both air and inert gas and water, with a minimum of 0 psi, so it will open and close reliably across that full range.
