ASCO 8220G7-240V Solenoid Valve

The ASCO 8220G7-240V Solenoid Valve is a high-performance, 2-way normally closed pilot-operated valve specifically engineered for demanding steam and hot water applications. Featuring a robust brass body and high-grade EPDM diaphragm, this valve ensures exceptional durability and thermal resistance in HVACR and industrial process environments. With a generous 13.5 Cv flow factor and 1-inch NPT connections, it delivers efficient fluid control for large-scale systems. The unit is powered by a 240Vac coil and integrated into a rugged NEMA 4X enclosure, providing superior protection against corrosion and harsh environmental conditions. Capable of handling operating pressure differentials from 5 to 50 PSI for steam and 5 to 150 PSI for hot water, this ASCO RedHat II series valve is an industry standard for reliability. Whether used in high-temperature sterilization, laundry equipment, or boiler systems, the ASCO 8220G7 provides precise pilot-operated actuation for critical shut-off requirements.

Key Benefits:

• High Flow Capacity: The 13.5 Cv rating allows for maximum flow with minimal pressure drop in 1-inch piping systems.
• Steam and Hot Water Optimized: Specifically designed to withstand fluid temperatures up to 300°F (steam) and 210°F (hot water).
• Environmentally Protected: The NEMA 4X watertight and corrosion-resistant enclosure ensures longevity in washdown or outdoor areas.
• Reliable Maintenance: A threaded bonnet design facilitates quick inspection and internal cleaning without removing the valve from the line.
• Long Lifecycle: Engineered for over 1 million cycles on hot water and 500,000 cycles on steam applications.

Common Questions:

What is the minimum pressure required for this valve to operate?
As a pilot-operated solenoid valve, the ASCO 8220G7 requires a minimum operating pressure differential of 5 PSI to open. Once open, it will typically remain functional down to 3 PSI.

Is this valve suitable for oily environments?
The included EPDM diaphragm is excellent for hot water and steam, but it is not recommended for media containing oils or greases, which can degrade the elastomer.

Can I mount this valve in any orientation?
While the 8220 series can be mounted in various positions, it is highly recommended to install the valve with the solenoid upright and vertical to prevent debris from accumulating in the core tube area.
