Overview
The Asco 8210G054 Red-Hat II solenoid valve is a 2-way normally closed general-purpose valve engineered for industrial fluid control. 1″ NPT brass construction with a 13 CV orifice delivers high flow rates while maintaining minimal internal leakage. This valve is rated for liquid, corrosive, and air/inert gas service across a wide range of industrial applications including car wash systems, laundry equipment, air compressors, and industrial water control.
Key Features
- 2-Way Normally Closed (Energize to Open) design for fail-safe operation
- Brass body construction with NBR (Buna-N) seals for corrosion resistance
- High-flow design (13 CV) rated for 0–145 GPM (water) and 0–1,281 SCFM (air)
- Red-Hat II watertight enclosure (Type 1, 2, 3, 3S, 4, 4X ratings) with dust-tight housing
- No minimum operating pressure required; may be mounted in any direction
- Resilient seals reduce internal leakage across service life
