ASCO 8025B204 Solenoid Valve

The ASCO 8025B204 Solenoid Valve is a robust 2-way normally closed valve engineered for precision fluid control in industrial HVACR and mechanical systems. Featuring a durable brass body and high-performance NBR diaphragm, this 1 1/2 inch NPT solenoid valve is optimized for handling air, inert gas, water, and light oil. Operating on 120Vac, it delivers a high flow capacity with a 22.5 Cv flow coefficient and manages pressures ranging from 5-125 PSI. A standout feature of this model is the no voltage release latched open manual reset mechanism, which ensures the valve remains open until manually reset after power loss, providing critical safety and process stability. Also identified as the ASCO 8025B204 120/60, this unit is designed for heavy-duty industrial automation where reliable flow regulation and localized control are paramount for system longevity and efficiency.

Key Benefits

• Mechanical Safety: The no voltage release manual reset function prevents accidental restarts, enhancing operator and system security.
• High Flow Efficiency: A significant 22.5 Cv rating allows for high-volume fluid transfer through a large 1.5-inch connection.
• Versatile Media Compatibility: The Buna-N (NBR) diaphragm ensures reliable sealing across multiple media including water and light oils.
• Rugged Construction: Built with a corrosion-resistant brass body to withstand demanding industrial environments.
• Simplified Integration: Standard 1 1/2" NPT threading and 120V/60Hz electrical specs allow for seamless installation into existing pipe networks.

Common Questions

How does the manual reset function work on the ASCO 8025B204?
This valve features a latching mechanism that requires a manual operation to open the valve; it will automatically close upon loss of voltage and must be manually reset to the open position once power is restored.

Can this solenoid valve be used for fuel oil applications?
Yes, the NBR seals and brass construction make it suitable for light oil applications, provided the viscosity and pressure remain within the 5-125 PSI operating range.

Is the 8025B204 compatible with 120/60 electrical systems?
Absolutely. The 8025B204 is identical to the model designated as 8025B204 120/60, making it a direct replacement for standard 120V AC industrial circuits.
