ASCO 8220G9-24V Solenoid Valve

The ASCO 8220G9-24V is a high-performance, 2-way normally closed solenoid valve specifically engineered for demanding steam and hot water service. Featuring a robust brass body and an 1 1/4" NPT connection, this pilot operated solenoid valve provides a high flow coefficient of 15 Cv, ensuring efficient fluid control in industrial boiler systems and laundry equipment. Designed for versatility, it manages operating pressure differentials from 5 to 50 PSI for steam and up to 150 PSI for hot water. The EPDM diaphragm offers superior thermal resistance, while the NEMA 4X enclosure provides a watertight and corrosion-resistant housing for the 24Vac coil, making it ideal for harsh wash-down environments. This reliable HVACR control valve is a critical component for maintaining precise thermal regulation in sterilization and process heating applications.

Key Benefits

• Dual-Media Efficiency: Specifically optimized to handle both high-temperature steam and hot water, reducing the need for multiple valve types in a single system.
• Industrial Durability: The rugged brass construction and EPDM diaphragm are built to withstand 1 million cycles on hot water, ensuring long-term reliability.
• Extreme Environment Protection: Integrated NEMA 4X enclosure protects electrical components against corrosion, dust, and hose-directed water.
• High Flow Performance: A 15 Cv rating allows for significant volume throughput, minimizing pressure drop across the 1 1/4" NPT ports.

Common Questions Can this valve be used for low-pressure gravity feed systems? No, as a pilot operated valve, the ASCO 8220G9-24V requires a minimum pressure differential of 5 PSI to open and function correctly. Is the coil compatible with DC power supplies? This specific model is designed for a 24Vac power supply. Using it with a DC source will result in coil failure or improper actuation; please confirm your controller voltage before installation. What causes a buzzing sound during operation? Buzzing is often caused by a voltage mismatch, loose electrical connections, or mineral buildup on the internal plunger. Routine cleaning and verifying the 24V supply can typically resolve this issue.
