Dayton 3A429 3-Way Solenoid Valve Trap 1/4 in Stainless Steel

SKU CH-BXZD-1J1R4 MPN 3A429

A 3-way stainless steel solenoid valve body, normally closed, with a 1/4 in port, 3/32 in orifice, Cv 0.17 and 0.22, rated for 90 psi air or water and 180 °F fluid temperature

  • TypeDrain Components
  • 3-way design directs fluid through multiple paths
  • Stainless steel body resists corrosion in harsh environments
  • Normally closed operation prevents flow until energized
  • Handles air, inert gas and water up to 90 psi
  • Rated for fluid temperatures up to 180 Degrees F

What this valve is and who needs it

The Dayton 3A429 is a three-way, two-position solenoid valve body built from stainless steel with a 1/4-inch nominal pipe size. It ships without a coil and defaults to normally closed operation. This part suits engineers and maintenance technicians who need a corrosion-rated valve body for air, inert gas or water lines in indoor or outdoor installations. It is not for buyers who need an integrated coil or a different port configuration.

The specification that decides fit

The body offers two Cv ratings of 0.17 and 0.22 through a 3/32-inch orifice and handles a maximum operating pressure differential of 90 psi for both air and water. Minimum differential is 0 psi and the maximum fluid temperature is 180 degrees F. If your system requires a higher flow coefficient, a larger orifice or a pressure rating above 90 psi, this valve body will not meet the requirement.

Installation notes and common issues

The valve body uses standard 1/4-inch pipe threads, so it threads into existing piping with common tools. Because the coil is sold separately, verify the coil voltage, enclosure rating and electrical connection before ordering. A frequent mistake is assuming the coil is included, which delays commissioning. Ensure the fluid type and temperature stay within the stated limits to avoid premature wear.

Questions about this item

What does the 0.17 Cv coefficient mean for flow through this valve?

A Cv of 0.17 indicates the valve passes 0.17 US gallons per minute of water at a 1 psi pressure drop, so it suits low-flow pilot or control circuits rather than high-volume lines.

How does the 1/4 inch NPT port limit the maximum pressure I can apply?

The 1/4 inch NPT stainless body is rated for 90 psi maximum differential pressure with air, inert gas or water, so system pressure must stay at or below that limit.

What clearance and pipe threading does the stainless body need for installation?

The valve requires a 1/4 inch NPT female thread on each port and enough wrench clearance around the hexagonal body to tighten without stressing the coil enclosure.
