Description
The ASCO 8263H300 is a direct-acting, 2-way normally closed solenoid valve engineered for demanding steam and hot water applications in commercial and industrial HVAC systems. Built with a durable brass body and Teflon seals, this valve delivers reliable shutoff and long service life even in high-temperature, high-pressure environments.
Key Features
- 2-way, normally closed (NC) direct-acting solenoid valve
- 1/4″ NPT pipe connection for easy inline installation
- 120VAC coil voltage for standard electrical compatibility
- Flow coefficient (Cv) of 0.52 for precise flow control
- Rated for steam service: 0–110 PSI operating pressure
- Rated for hot water service: 0–210 PSI operating pressure
- Brass body construction for corrosion resistance and durability
- Teflon seals for compatibility with steam and hot water media
- NEMA 4X enclosure rating — suitable for wet, corrosive, and washdown environments
Application
The ASCO 8263H300 is ideal for use in boiler systems, steam distribution, hot water heating loops, and industrial process control where a compact, reliable solenoid valve is required. The NEMA 4X enclosure makes it well-suited for harsh or outdoor environments where moisture and corrosive elements are present.
