ASCO 8210G9HW-12VDC Solenoid Valve

The ASCO 8210G9HW-12VDC is a high-flow, 2-way normally closed solenoid valve engineered specifically for high-temperature hot water applications. This 3/4 inch NPT solenoid valve features a robust brass body construction and a durable EPDM diaphragm, capable of handling media temperatures up to 150°F. Operating on a 12VDC power supply, it utilizes a pilot-operated internal construction to provide a high flow coefficient (Cv) of 5.0. Designed for reliability in demanding environments, the valve includes a NEMA 4X enclosure for superior protection against corrosion and moisture ingress. With a pressure rating of 5-100 PSI, this unit ensures precise control in industrial hot water systems and specialized HVACR plumbing circuits where low-voltage DC operation is a technical requirement. Its rugged internal components are optimized for ASCO 8210 series replacements, minimizing pressure drop while maintaining a tight shut-off in critical flow paths.

• Optimized Flow Performance: A 5.0 Cv rating ensures minimal pressure loss across 3/4" pipe runs.
• Environmental Protection: The watertight NEMA 4X housing protects the 12VDC coil from harsh wash-down conditions and corrosion.
• Thermal Resilience: Specialized EPDM elastomers are rated for hot water service up to 150°F, preventing premature diaphragm failure.
• Reliable Pilot Operation: Designed to function efficiently within a 5 to 100 PSI differential pressure range.

What is the minimum pressure differential required for this valve?
This pilot-operated valve requires a minimum 5 PSI pressure differential to lift the diaphragm and ensure proper opening and closing cycles.

Can this solenoid valve be mounted in any orientation?
While it can be mounted in various positions, it is highly recommended to install the valve with the 12VDC solenoid coil in the upright and vertical position to prevent sediment buildup in the core tube.

Is this unit compatible with potable water systems?
The 8210G9HW is specifically designed for hot water service using EPDM seals; however, always verify local plumbing codes regarding lead-free requirements for specific potable water applications.
