Dayton 2A197 1/4 in Brass Steam Solenoid Valve Trap

SKU CH-YKQN-00TDF MPN 2A197

A brass, normally-closed 1/4 in solenoid valve body rated for 150 psi water and 400 °F fluid temperature

  • TypeDrain Components
  • Brass body resists corrosion for long service life
  • Normally closed design stops flow when de-energised
  • 1/4 in NPT connection fits standard piping
  • 34 Cv rating suits low-flow steam applications
  • Rated to 400 °F fluid temperature for steam systems

Brass Steam Solenoid Valve Body

This brass solenoid valve body is a 2-way, 2-position drain component designed for steam service. It features a normally closed configuration with a 1/4 inch nominal pipe size and a 1/8 inch orifice diameter. The unit has a Cv of .34 and a maximum fluid temperature of 400 Degrees F.

For Steam Systems Requiring Normally Closed

This valve suits installations needing a brass body rated for up to 150 psi water pressure differential and indoor or outdoor use. It is not for buyers requiring an integrated coil or actuation for air or inert gas at rated pressures. Buyers needing a larger port size or different body material should look elsewhere.

Integrates Into Steam Drain Assemblies

The valve body accepts a separate coil to complete the actuated assembly for automatic condensate removal. Its brass construction handles the 400 Degrees F maximum fluid temperature in steam trap applications. The 1/4 inch connection fits standard piping without requiring adapters for that size.

Questions about this item

What size pipe thread does the 1/4 in brass valve body require?

The valve body uses a 1/4 in nominal pipe thread so the mating pipe or fitting must match that size.

Will the 0.34 Cv flow coefficient handle the same steam load as my old 1/2 in trap?

The 0.34 Cv rating is fixed by the 1/8 in orifice; a larger trap would have a higher Cv so the two are not directly interchangeable.

How can I verify the solenoid is actuating correctly after wiring the coil?

Apply the rated coil voltage and listen for the click; the valve should open and allow flow up to 150 psi water or 400 °F steam when energised.
