ASCO 8210B20 Solenoid Valve

The ASCO 8210B20 is a high-performance 2-way normally closed solenoid valve designed for reliable control of air and inert gas, as well as water. Engineered with a durable brass body and reliable NBR seals, this pilot-operated valve features a 1/4" NPT connection and a 1.0 Cv flow coefficient. It operates efficiently within a pressure range of 5 to 125 PSI, making it a standard choice for general service applications in HVACR and industrial fluid control. The unit includes a 120V/60Hz AC coil and is housed in a NEMA 1 enclosure, suitable for indoor field installation. This pilot operated solenoid valve is known for its high flow capacity and robust diaphragm construction, ensuring consistent seating and long-term cycle life in demanding environments. Technicians frequently specify the ASCO 8210 series for its ease of maintenance and predictable 0.60-watt power consumption in standby configurations.

• Optimized Flow: High 1.0 Cv rating supports efficient fluid movement in air and water systems.
• Rugged Construction: Forged brass body provides structural integrity for high-pressure 120V solenoid valve operations.
• Reliable Sealing: Nitrile Butadiene Rubber (NBR) seals offer Excellent compatibility with standard non-corrosive media.
• Standardized Installation: NEMA 1 rated junction box housing allows for straightforward electrical terminations.

How do I install the ASCO 8210B20 in a vertical line?
While this valve is designed for universal mounting, it is recommended to install it with the solenoid vertical and upright to prevent sediment buildup in the core tube area.

What is the minimum pressure differential required for operation?
Being a pilot-operated valve, the 8210B20 requires a minimum 5 PSI differential to ensure the diaphragm lifts and seals correctly during the cycle.

Can this valve be used for steam applications?
No, this specific model is rated for air, inert gas, and water. For steam service, a valve with EPDM or PTFE seals and a high-temperature coil is required.
