Asco 8158A120X1X0000 3 Inch NPT Gas Safety Shut-Off Valve Body

The Asco 8158A120X1X0000 is a 3-inch NPT gas safety shut-off valve body from the Series 158 line, specifically engineered for on/off control of commercial and industrial gas burners in boiler and burner applications. This two-way normally closed valve body features aluminum construction and is designed exclusively for use with the Asco Series 159 motorized actuator (sold separately).

Key Features:

• 3-inch NPT threaded end connectors for secure installation
• Two-way normally closed configuration for fail-safe operation
• Push-to-open design activated by Series 159 motorized actuator
• Internal return spring closes valve in less than 1 second when actuator is de-energized
• High close-off pressure rating of 75 PSI (5.2 bar) for enhanced safety
• Superior flow capacity - twice that of comparable combustion valves
• Ambient temperature rating: -40°F to 150°F (-40°C to 66°C)
• Aluminum body construction for durability and corrosion resistance

This valve body is ideal for applications including boilers, burners, ovens, furnaces, kilns, thermal oxidizers, incinerators, HVAC equipment, and gas generators. The Series 158 meets current NFPA, UL, CSA, FM Global, RoHS, and EN standards for gas safety applications. The high close-off pressure ensures safe shutoff in the event of fuel train system failure, eliminating the need for additional safety components.
