ASCO 8210B57 Solenoid Valve

The ASCO 8210B57 Solenoid Valve is an industrial-grade, 2-way normally open solenoid valve engineered for high-performance fluid control in HVAC and commercial plumbing systems. Featuring a durable brass body and reliable NBR seals, this 1-inch NPT solenoid valve is a pilot operated powerhouse capable of managing a wide range of media, including air, water, and light oil. With a high 13 Cv flow factor and a standard 120V AC coil, it ensures efficient operation in demand-heavy environments such as car washes and air compressors. Designed for low pressure solenoid valve applications, it maintains a consistent 0-125 PSI pressure rating while housed in a protective NEMA 1 enclosure. This general service valve is specifically built to remain open until energized, making it an essential component for safety and fail-safe operations where constant flow is required during power loss.

• Corrosion-Resistant Construction: The rugged brass body ensures long-term durability in moisture-rich environments.
• High Flow Capacity: A 13 Cv factor allows for significant fluid movement through the 1-inch orifice.
• Versatile Media Compatibility: Effectively controls air, water, and light oils (up to 300 SSU).
• Fail-Safe Design: The normally open configuration allows media to flow freely whenever the valve is de-energized.
• Standard Electrical Integration: Ready for 120V/60Hz systems, fitting seamlessly into most North American commercial grids.

What is the difference between Normally Open and Normally Closed ASCO valves?
A Normally Open (NO) valve like the ASCO 8210B57 remains open when there is no power, allowing continuous flow. It only closes when electrical current is applied to the coil. Conversely, Normally Closed (NC) valves block flow until energized.

Can this solenoid valve be used for steam applications?
No, this specific model features NBR seals designed for air, water, and light oil up to 180°F. Steam applications typically require EPDM or PTFE seals and different pressure ratings.

What does 'Pilot Operated' mean for this 1-inch NPT valve?
Pilot operation means the valve utilizes the fluid pressure in the line to assist in moving the internal diaphragm. This allows for the control of larger flow rates with a smaller, more energy-efficient solenoid coil.
