Brass Solenoid Valve for Cryogenic Drains

The Red Hat 8263H240LT is a normally closed 2-way solenoid valve built for cryogenic drain applications. Its brass body and PTFE seals handle air or inert gas at pressures up to 155 psi. The 1/8 inch nominal pipe size and .35 Cv rating suit low-flow control tasks. It operates on 110V or 120V AC power without a junction box.

Integration Needs and Space Savings

This valve installs directly into 1/8 inch piping using its brass connections. The watertight coil enclosure removes the need for a separate junction box in damp environments. A 1/8 inch orifice allows precise metering in tight drain assemblies. The normally closed configuration stops flow automatically when power is removed.

Ideal for Low-Flow Cryogenic Lines

Technicians maintaining cryogenic drain traps or low-pressure inert gas vents will find the pressure and temperature ratings appropriate. Buyers needing fuel gas or fuel oil service should look elsewhere because those pressure ratings are not applicable. Systems requiring higher flow coefficients or larger pipe diameters will need a different valve.

Questions about this item

What limits continuous operation of the 0.35 Cv brass valve at 155 psi?

The PTFE seal and brass body set the pressure ceiling at 155 psi for air and inert gas, so sustained flow stays within that differential without exceeding the valve's rated maximum.

How much heat and noise does the 120 V AC coil produce during all-day duty?

The coil enclosure is watertight without a junction box, and the valve draws standard AC power for a 1/8 in orifice; heat rises with continuous energising but stays within normal solenoid limits.

What piping and voltage must already be in place for this normally-closed valve to work?

You need 1/8 in NPT connections matching the brass body and a 110–120 V AC supply; the valve opens only when that voltage is applied to the coil.
