Dayton 2A202 Brass Steam Solenoid Valve Trap 1 1/2 in

SKU CH-XVAY-C70ES MPN 2A202

A brass solenoid valve body for steam systems, normally closed with a 1 1/2 in orifice and 25 Cv flow capacity

  • TypeDrain Components
  • Brass construction resists corrosion in steam systems
  • 25 Cv rating delivers high flow capacity
  • Normally closed design prevents unintended fluid passage
  • Operates up to 400 °F for demanding steam applications
  • Suitable for indoor and outdoor installations

Brass Solenoid Valve for Steam Systems

The Dayton 2A202 is a normally closed, two-way brass valve body designed for steam, water and inert gas lines. It suits plant engineers and maintenance teams who need a 1 1/2 inch nominal pipe size with a 25 Cv flow coefficient and a 400 Degrees F maximum fluid temperature.

Pressure Limits and Environmental Rating

The valve requires a minimum 5 psi differential to operate and handles water up to 150 psi maximum differential; air and inert gas maximum is not rated. Its brass construction carries an indoor and outdoor environmental rating, and the body contains chemicals flagged under California Proposition 65 for cancer and reproductive harm.

Coil-Free Body for Custom Actuation

Supplied without a coil, the 2A202 lets installers select the voltage and enclosure that match their control panel. The 1 1/2 inch orifice matches the pipe size, simplifying piping layout, while the normally closed configuration fails safe on power loss. Buyers who need an integrated coil or a different pressure class must choose another model.

Questions about this item

How do I install the 1 1/2 in brass solenoid valve body and which step is most often missed?

Pipe the valve into a 1 1/2 in line with flow matching the arrow, then mount the coil onto the operator threads; the step most often missed is applying the correct torque to the coil nut so the plunger seals at the 5 psi minimum differential.

What maintenance or replacement will the brass valve trap need over time?

Plan to inspect the brass body and internal seals for scale or wear after extended exposure to 400 °F steam; replace the coil if it fails to hold the 25 Cv flow at the 150 psi water limit, and rebuild or swap the valve body if leakage appears across the seat.

What is the first operating limit reached under sustained high-temperature steam service?

The fluid temperature ceiling of 400 °F is the first hard limit; sustained steam at or above that temperature will degrade the brass body and seals faster than the 150 psi pressure rating or the 5 psi minimum differential.
