ASCO 8210G9HW-208V Solenoid Valve

As a seasoned technician, you know that ASCO 8210G9HW-208V is the standard for reliable hot water service solenoid valves in demanding HVACR and boiler applications. This 2-way normally closed solenoid valve is engineered specifically for high-frequency cycling, featuring a 3/4 inch NPT connection and a robust brass body. The EPDM diaphragm is rated for fluid temperatures up to 210°F, making it a critical component for laundry equipment, industrial water control, and hydronic systems. With a 5 Cv flow factor and a required operating pressure differential of 5-125 PSI, this pilot-operated valve ensures high-flow performance with low internal leakage. The 208Vac coil is protected by a Nema 4X enclosure, providing superior resistance to corrosion and moisture in mechanical rooms. Whether you are performing a direct replacement or a new install, this valve delivers the durability required for industrial water control.

Key Benefits:

• High-Temperature Resilience: Equipped with an EPDM diaphragm rated for hot water applications up to 210°F.
• Commercial Grade Protection: The Nema 4X enclosure provides watertight and corrosion-resistant protection for the 208V coil.
• Reliable Flow Characteristics: Features a high 5 Cv flow factor for efficient 3/4 NPT solenoid valve operation in pressurized systems.
• Rugged Construction: A heavy-duty brass body ensures long service life and structural integrity under constant thermal stress.

Common Questions:

What is the minimum pressure required for this valve to open?
This is a pilot-operated valve, meaning it requires a minimum pressure differential of 5 PSI across the inlet and outlet to function correctly.

Can this valve be used for steam service?
No, the ASCO 8210G9HW-208V is specifically designed for hot water up to 210°F. For steam applications, a different seal material and series would be required to handle the higher temperatures and pressures.

Does this valve come with a 208V coil installed?
Yes, this specific model is configured with a 208Vac coil. Ensure your control circuit matches this voltage before installation to avoid coil burnout.
