ASCO 8210G9HW Solenoid Valve

The ASCO 8210G9HW is a high-performance 2-way normally closed solenoid valve specifically engineered for demanding hot water service applications. Featuring a robust brass body and high-grade EPDM diaphragms, this valve provides reliable flow control for fluids up to 210°F. The 3/4" NPT connection and 5 Cv flow factor ensure efficient throughput in high-demand HVACR systems. Operating on standard 120Vac, this 8210 series valve is rated for a pressure range of 5 to 125 PSI, making it a staple for commercial boiler feeds and industrial heating loops. The integrated NEMA 4X enclosure offers superior protection against corrosion and moisture ingress, ensuring long-term terminal performance in harsh environments. This pilot-operated mechanical assembly is designed for low-maintenance operation and consistent cycle life in pressurized water systems.

• Optimized for Hot Water: Rated for temperatures up to 210°F with specialized EPDM internal components.
• Durable Construction: Rugable brass body provides structural integrity for high-pressure 125 PSI applications.
• Environmental Protection: The NEMA 4X rated solenoid housing prevents damage from washdown or corrosive atmospheres.
• High Flow Capacity: A 5 Cv rating allows for significant fluid movement through 3/4" piping.
• Reliable Shifting: Normally closed configuration ensures immediate shut-off during power loss or de-energization.

Frequently Asked Questions

What is the maximum pressure differential for the 8210G9HW?
This valve requires a minimum of 5 PSI differential to open and is rated for a maximum operating pressure differential of 125 PSI on hot water service.

Can this ASCO valve be mounted in any orientation?
For optimal performance and to prevent sediment buildup in the solenoid operator, it is recommended to mount the valve with the solenoid upright and vertical.

Is the EPDM diaphragm compatible with steam?
No, the 8210G9HW is specifically designed for hot water. For steam applications, a valve with PTFE or specialized elastomers should be specified.
