ASCO 8215B50 Shut Off Valve

The ASCO 8215B50 is a high-performance 1" NPT gas solenoid valve engineered for precision and safety in low-pressure fuel gas systems. This 2-way normally closed shut-off valve is constructed with a rugged aluminum body and durable NBR seals, making it an ideal choice for commercial and industrial gas safety shut-off applications. Operating at 120V AC, the ASCO RedHat series provides a high flow capacity (21 Cv) and is designed to handle media including natural gas, propane, and air with a maximum operating pressure of 25 PSI. Its internal pilot-operated design ensures reliable performance even at zero pressure differential, which is essential for HVACR gas combustion monitoring and double block-and-vent burner configurations. This lightweight, cost-effective solution is widely utilized in boilers, furnaces, and commercial kitchens to prevent hazardous leaks and ensure precise flow control.

Key Benefits:

• Fail-Safe Security: The normally closed operation ensures the valve remains shut when de-energized, effectively preventing accidental gas flow.
• Broad Media Compatibility: Versatile enough for natural gas, LPG, and inert gas service in diverse environmental conditions.
• High-Flow Efficiency: Features a 21 Cv flow rate to maintain 1,119,000 BTU/hr capacity for demanding heating equipment.
• Industrial Durability: Built with aluminum body construction and stainless steel internals for long-term resistance to wear.
• Zero Minimum Pressure: Operates reliably from 0 to 25 PSI without requiring a minimum pressure differential.

Common Questions:

How do I troubleshoot an ASCO 8215B50 that won't open?
First, verify that the 120V power supply is active and the solenoid coil has continuity. Check for debris or blockages in the line and ensure the operating pressure does not exceed the 25 PSI limit, as excessive pressure can prevent the pilot from shifting.

Can this valve be used for outdoor gas lines?
The standard ASCO 8215B50 features a NEMA 1 general-purpose enclosure. For outdoor or wash-down environments, ensure the valve is equipped with a watertight NEMA 4 or 4X "RedHat II" solenoid enclosure to prevent moisture ingress.

Is the ASCO 8215B50 suitable for vacuum service?
Yes, the 8215 series is specifically designed to handle both air and vacuum service, making it a flexible choice for various industrial pneumatic and combustion applications.
