ASCO 8210G9HW-24V Solenoid Valve

The ASCO 8210G9HW-24V is a heavy-duty 2-way normally closed solenoid valve engineered specifically for high-temperature hot water applications. Built with a rugged brass body and high-grade EPDM diaphragm, this valve handles fluid temperatures up to 210°F, making it a reliable choice for boiler feed lines and hydronic heating systems. It features a 3/4" NPT connection and a robust 5.0 Cv flow coefficient, ensuring efficient fluid handling within a pressure range of 5 to 125 PSI. The internal pilot-operated disc construction allows for high-flow performance while the NEMA 4X enclosure provides superior protection against corrosion and moisture in demanding mechanical rooms. Operating on 24V/60Hz power, this ASCO 8210 Series valve is the industry standard for contractors requiring precise flow control and long-term durability in pressurized hot water loops without the risk of premature seal failure.

• High-Temperature Compatibility: Rated for hot water service up to 210°F with specialized EPDM elastomers.
• High Flow Capacity: A 5.0 Cv rating provides consistent throughput for 3/4" piping systems.
• Industrial Protection: NEMA 4X rated watertight and dust-tight housing prevents electrical failure in harsh environments.
• Reliable Operation: Pilot-operated design ensures positive shut-off and consistent opening under minimum differential pressure.
• Durable Construction: Forged brass body provides the structural integrity needed for commercial HVACR infrastructure.

What is the minimum pressure required for this valve to cycle?
The ASCO 8210G9HW requires a minimum differential pressure of 5 PSI to ensure the diaphragm lifts and closes correctly.

Can this solenoid valve be used for steam applications?
No, this specific model is rated for hot water service up to 210°F; for low or high-pressure steam, a valve with PTFE or specialized steam-rated internals is required.

Is the coil on the 8210G9HW replaceable?
Yes, the 24V coil can be replaced if electrical failure occurs, allowing the brass valve body to remain in the piping system for faster service.
