ASCO 8210G9HW-240V Solenoid Valve

The ASCO 8210G9HW-240V is a heavy-duty 2-way normally closed solenoid valve designed specifically for demanding hot water service applications. Featuring a rugged brass body and high-grade EPDM diaphragm, this valve manages media temperatures up to 210°F with a consistent 5.0 Cv flow coefficient. This 3/4 inch NPT solenoid valve operates on a 240V/60Hz AC power supply and includes a NEMA 4X waterproof enclosure, making it suitable for washdown environments and outdoor installations. Engineered for high-pressure hot water systems, it maintains a reliable pressure differential of 5 to 125 PSI. Contractors prefer this model for its pilot operated design, which ensures efficient shut-off and opening in commercial boiler loops and industrial process water systems. The lead-free construction and robust internal components offer long-term performance in high-cycle environments where thermal expansion and fluid compatibility are critical factors for system uptime and mechanical integrity.

• High Temperature Performance: Rated for hot water service up to 210°F with specialized EPDM elastomers.
• Environmentally Protected: Standard NEMA 4X enclosure provides superior protection against corrosion and moisture ingress.
• Optimal Flow Rate: 5.0 Cv rating ensures minimal pressure drop across 3/4" NPT piping architectures.
• Robust Construction: Forged brass body provides the mechanical strength necessary for industrial plumbing and HVACR applications.
• Reliable Actuation: 240Vac coil allows for integration into standard commercial electrical panels and control circuits.

What is the minimum pressure required for this valve to operate?
This is a pilot-operated valve and requires a minimum pressure differential of 5 PSI to functionally open and close the diaphragm.

Can the ASCO 8210G9HW be used for steam applications?
No, this specific model is optimized for hot water service up to 210°F; steam applications require a different elastomer configuration and insulation class.

Is the coil replaceable without removing the valve body from the line?
Yes, the ASCO RedHat design allows for coil replacement or maintenance without breaking the 3/4" pipe connections, reducing labor time during service calls.
