ASCO 8215G20B-24V Solenoid Valve

The ASCO 8215G20B-24V is a high-flow, 2-way normally closed solenoid valve engineered specifically for low-pressure gas combustion systems. Designed with a robust aluminum body and reliable NBR seals, this valve provides a secure 0 to 5 psi gas shutoff for propane and natural gas applications. This 1/2 inch NPT gas valve features a high-capacity 4.4 Cv flow coefficient, supporting up to 238,500 BTU/hr. Operating on a 24Vac coil, it integrates seamlessly into standard HVACR control circuits. The NEMA 4X enclosure ensures protection against corrosion and moisture, making it suitable for demanding mechanical rooms. This ASCO RedHat gas valve is a precision component for gas furnace solenoid replacement and commercial boiler fuel trains, providing the fast-acting closing speeds required for safety-critical fuel gas shutoff sequences.

• Industrial-Grade Construction: Features a lightweight yet durable aluminum die-cast body rated for fuel gas service.
• Superior Flow Dynamics: The 4.4 Cv rating allows for high-volume gas delivery with minimal pressure drop across the orifice.
• Resilient Sealing: Nitrile (NBR) elastomers ensure bubble-tight shutoff and compatibility with standard fuel gases.
• Enhanced Environmental Protection: The NEMA 4X watertight electrical housing allows for installation in harsh or wash-down environments.
• Direct Acting Design: Provides reliable operation even at zero-pressure differentials, ensuring gas flow control is maintained at all times.

Common Technical Questions

What is the maximum pressure rating for the ASCO 8215G20B-24V?
This specific model is designed for low-pressure gas applications with a maximum operating pressure differential (MOPD) of 5 PSI.

Can this valve be mounted in any orientation?
For optimal service life and to prevent debris accumulation in the core tube, it is recommended to mount the valve with the solenoid upright and vertical, though it can be installed in other positions if necessary.

Is this solenoid valve compatible with 24V DC systems?
No, the 8215G20B-24V is specifically wound for 24Vac/60Hz. Using it with a DC power source will result in coil failure or improper actuation.
