ASCO S262SH02N3KK4 Vent Valve

The ASCO S262SH02N3KK4 Vent Valve is a high-performance, 2-way normally open solenoid valve specifically engineered for the safe management of combustible gases and clean air in industrial heating systems. Featuring a robust die-cast aluminum body and a 2 1/2-inch NPT connection, this pilot-operated gas vent valve is designed to exhaust downstream gas to the atmosphere when the system is de-energized, preventing pressure buildup. It operates reliably on a 120V AC solenoid and is rated for a pressure range of 0 to 15 psi. As a direct replacement for 8215B93, the S262SH02N3KK4 ensures seamless integration into existing boiler and furnace manifolds. Its zero differential piloted diaphragm and rapid response time of less than one second make it a critical component for maintaining secondary safety in commercial and industrial combustion applications. This ASCO fuel gas valve is built to withstand ambient temperatures from -20°F to 170°F and includes 1/8" NPT pipe taps for simplified routine testing.

Key Benefits

• Efficient Pressure Relief: Optimized for venting natural gas and propane in burner manifolds, ensuring system safety during shutdown.
• Industrial Durability: The lightweight yet rugged die-cast aluminum construction provides excellent corrosion resistance and long-term stability.
• Direct Cross-Compatibility: Engineered specifically as the manufacturer-recommended replacement for 8215B93, reducing downtime during maintenance.
• Rapid Actuation: The high-flow 123 Cv capacity and solenoid-operated pilot design allow for fast opening and closing in under one second.
• Simplified Testing: Integrated 1/8" NPT taps allow technicians to perform routine pressure checks without disconnecting the main line.

Common Questions

The S262SH02N3KK4 is the current, high-efficiency direct replacement for 8215B93. It maintains the same 2-1/2" pipe size and normally open functionality while meeting updated industrial safety standards for gas combustion systems.

Because the S262SH02N3KK4 utilizes a K4 orifice size (larger than 1-1/2"), it must be mounted in the upright position to ensure the pilot-operated diaphragm functions correctly and prevents sluggish operation.

This normally open gas valve is primarily rated for indoor environments with an ambient temperature range of -20°F to 170°F. For specific outdoor settings, ensure it is protected by a NEMA-rated enclosure to prevent moisture ingress into the solenoid coil.
