ASCO 8210G2HW-24V Solenoid Valve

The ASCO 8210G2HW-24V Solenoid Valve is a 2-way normally closed, pilot-operated unit engineered specifically for hot water service. This veteran-grade 1/2" NPT brass solenoid valve features a high-performance EPDM diaphragm, allowing for a 4 Cv flow factor and reliable operation in fluid temperatures up to 210°F. Operating on a 24Vac control circuit, this valve is built for rigorous industrial environments, protected by a NEMA 4X watertight enclosure. With an operating pressure differential of 5-125 PSI, it ensures low internal leakage and a long service life in boiler systems, laundry equipment, and industrial water control. The internal pilot operation provides efficient shifting, while the robust brass body resists corrosion in standard hydronic applications. Professionals value the ASCO RedHat design for its simplified maintenance, as the internal components can be serviced without removing the valve body from the line, ensuring minimal downtime during routine HVACR system repairs.

• High-Temperature Durability: Specifically compounded EPDM diaphragm handles hot water up to 210°F without premature degradation.
• Environmental Protection: The NEMA 4X enclosure provides superior resistance to corrosion and moisture in demanding mechanical rooms.
• Efficient Flow: A 4 Cv flow coefficient ensures high-volume liquid transfer with minimal pressure drop across the 1/2" orifice.
• Versatile Installation: Designed to function in any mounting position, though vertical-upright is recommended to prevent sediment buildup.

Is the ASCO 8210G2HW-24V compatible with steam applications?
No, this specific model is optimized for hot water service. For high-pressure steam, a valve with PTFE or stainless steel internals rated for higher temperatures is required.

What is the minimum pressure required for this valve to open?
As a pilot-operated valve, it requires a minimum pressure differential of 5 PSI to lift the diaphragm and maintain a fully open position.

Can I use this valve for light oil service?
While the brass body is sturdy, the EPDM seals in the 'HW' suffix models are designed for water and can be damaged by petroleum-based oils. Use NBR or Viton models for oil applications.
