Stainless steel solenoid valve, 1/2 inch NPT, 110/120V AC coil

Red Hat

Red Hat EF8210G037 Solenoid Valve Trap 1/2 in 110/120V AC

SKU CH-3VXE-YB5A3 MPN EF8210G037

A 1/2-inch normally-closed solenoid valve with stainless-steel body, NBR seals and 2.2 Cv flow for 110/120 V AC air or inert-gas lines up to 150 psi

  • TypeDrain Components
  • 1/2 in NPT connection fits standard pipework
  • 2 Cv high-flow design moves fluid efficiently
  • Stainless steel body resists corrosion in harsh environments
  • NBR seals handle air and inert gas up to 150 psi
  • 110/120 V AC coil enables direct mains-powered operation

Solenoid valve for 1/2 in pipe

The Red Hat EF8210G037 is a two-way, normally closed solenoid valve with a 1/2 inch nominal pipe size. Its stainless steel body and NBR seals suit air or inert gas systems. The valve provides a Cv of 2.2 through a 7/16 inch orifice. It operates on 110 or 120V AC power.

Suits high-flow air or inert gas lines.

This valve handles air and inert gas up to 150 psi differential pressure. Buyers needing fuel gas or fuel oil service should look elsewhere because those pressure ratings are not applicable. The normally closed configuration fits automatic drain or shut-off tasks. Installers requiring a different voltage or pipe size must select another model.

150 psi maximum operating pressure differential

The 150 psi limit on air and inert gas is the key figure for specifying this valve. Exceeding it risks leakage or failure. Fuel gas and fuel oil duties are not rated. The 2.2 Cv and 7/16 inch orifice define the flow capacity at that pressure.

Questions about this item

How often should the NBR seals on the EF8210G037 be inspected or replaced under normal service?

Inspect the NBR seals annually; replace them if they show cracking, hardening or leakage, which typically occurs after several years depending on fluid type and cycle frequency.

What is the maximum operating pressure differential the EF8210G037 can handle continuously on air or inert gas?

The valve is rated for a maximum operating pressure differential of 150 psi on air or inert gas; sustained operation at this limit is the primary constraint.

How warm does the coil get when the EF8210G037 is energised continuously at 110/120V AC?

The coil runs warm during continuous duty at 110/120V AC; ensure adequate ventilation around the stainless steel body to dissipate heat.
