ASCO 8210G202-24V Solenoid Valve

The ASCO 8210G202-24V Solenoid Valve is a rugged, 2-way normally closed pilot-operated valve engineered for reliable control in high-demand HVACR and industrial fluid systems. Built with a durable brass body and high-performance NBR seals (Nitrile), this 1/2" NPT valve is optimized for general service applications involving air and water. Operating on a 24Vac control circuit, it features a flow coefficient of 3 Cv and supports a functional pressure range of 5-150 PSI. The integration of a NEMA 4X enclosure ensures superior protection against corrosion and water ingress, making it suitable for washdown environments or outdoor installations. This pilot-operated solenoid requires a minimum differential pressure of 5 PSI to ensure consistent shifting and peak performance. Designed for longevity in the field, the internal components are easily accessible for maintenance or rebuilds without removing the valve body from the piping.

• High Flow Efficiency: The 3 Cv flow coefficient provides optimal throughput for 1/2" pipe sizing, reducing pressure drop across the seat.
• Environmental Resilience: NEMA 4X rating provides a watertight and corrosion-resistant housing for sensitive electrical components.
• Broad Pressure Window: Reliable operation from 5 to 150 PSI, ideal for commercial water lines and compressed air systems.
• Serviceability: Standardized internal design allows for rapid diaphragm or coil replacement to minimize system downtime.

Common Questions

What is the minimum operating pressure for this valve?
This is a pilot-operated valve; it requires a minimum differential pressure of 5 PSI to open the main orifice. It will not function correctly in gravity-fed or zero-pressure systems.

Can this valve be used for steam or high-temperature fluids?
The standard NBR seals are rated for general air and water service. For steam or fluid temperatures exceeding the standard rating, a valve with EPDM or Viton seals and a Class H coil is required.

Is the coil replaceable without de-piping the valve?
Yes, the 24V solenoid coil can be swapped out by removing the retaining clip, allowing for electrical repairs while the brass body remains inline.
