ASCO 8214G20-24V Solenoid Valve

The ASCO 8214G20-24V is a rugged, 2-way normally closed fuel gas shutoff valve engineered for critical combustion control in commercial and industrial burners. This 1/2" NPT valve features a high-flow 4.4 Cv capacity, supporting up to 238,500 BTU/hr to handle a variety of high-demand heating applications. Built with a die-cast aluminum body and resilient NBR seals, it ensures reliable performance and bubble-tight shutoff within a 0-5 PSI pressure range. The 24V AC coil is protected by a NEMA 4X enclosure, providing superior resistance to water and corrosion in demanding mechanical rooms. As a pilot-operated solenoid valve, it offers a zero-minimum differential design, allowing for consistent operation even in low-pressure gas lines. Technicians prioritize the 8214 series for its integrated 1/8" NPT upstream and downstream pipe taps, which simplify routine pressure testing and system diagnostics without breaking the line.

• Zero-Minimum Differential: Reliable fuel gas safety shutoff even at 0 PSI inlet pressure.
• High Flow Capacity: 4.4 Cv rating ensures optimal gas supply for boilers and furnaces.
• Environmental Protection: NEMA 4X airtight enclosure maintains terminal integrity in washdown or corrosive areas.
• Diagnostic Convenience: Factory-installed 1/8" NPT test ports for rapid manifold pressure verification.
• Rapid Response: Fast-acting solenoid design for immediate fuel interruption in safety-critical scenarios.

What are the primary causes of solenoid "chattering" in this valve?
Chattering is typically caused by insufficient voltage to the 24V coil or a mechanical obstruction preventing the plunger from seating. Ensure your transformer is appropriately sized for the inrush current of the ASCO 8214G20-24V.

Can this valve be mounted in a vertical orientation?
Yes, the 8214 series is multi-poise, though mounting with the solenoid upright is the industry standard to prevent sediment buildup in the core tube. Always check for proper flow direction indicated on the aluminum valve body.

Is this valve compatible with Propane (LP) gas?
Yes, the NBR seals and aluminum construction are rated for both Natural Gas and Propane, making it a versatile 2-way solenoid valve for various fuel gas trains.
