Pulse firing increases productivity and reduces emissions in multi-burner gas-fired furnace systems. This technique, which involves “pulsing” the burners in ON/OFF or high-fire/low-fire cycles, offers greater temperature control and fuel efficiency. It also maximizes air circulation and homogenizes the heat within the furnace. To unlock the many benefits of pulse firing, burner systems require robust valves that can withstand frequent opening and closing to properly regulate heat.

The ASCO Series 214, also known as 8214, high-flow, low-pressure (5 psi) gas safety shutoff valves are specifically designed for on-off control of fuel gas in commercial and industrial gas burners. Their unique double-disc design with over travel provides redundant sealing for leak-tight shutoff on pilot or main gas lines. Optional flange allows for double-solenoid & solenoid-motorized valve construction to allow for modularity and ease of mounting. The valves are ideal for natural gas fired boilers, furnaces, grain dryers, kilns, gas generators and commercial kitchen/cooking equipment.
The ASCO Series 215, is an aluminum body, lightweight gas safety shut off valve for high flow applications. The pilot operated construction works from zero pressure differential with resilient soft seating for tight shut off. Optional flange allows for double-solenoid & solenoid-motorized valve construction to allow for modularity and ease of mounting. The 215 Series is ideal for vacuum service, oxygen service, heating equipment applications, and long-life applications.
The ASCO Series 290 is a pressure-operated, direct acting angle-body piston valve built for demanding applications. Its straight-through body design is available in bronze or stainless steel. The valve is suitable for general service applications (air, inert gas, water, oil), plus steam, hot water, and auxiliary fluids. A large range of options, certifications and characteristics is available.
