Conbraco 50-GB5-A1 Valve

The Conbraco 50-GB5-A1 is a professional-grade 1" female NPT gas shutoff ball valve engineered for high-capacity main burner applications. Built with a rugged ASTM B584 bronze body, this 2-piece valve features a specialized 1/4" NPT pilot tapping, making it a critical component for systems requiring streamlined pilot light or pressure gauge integration. Designed to handle up to 3,144,000 BTU/hr, it provides reliable performance for natural gas, LP gas, and mixed gas configurations. The unit comes equipped with a low-profile tee handle, ideal for tight mechanical spaces where standard lever handles may cause interference. To ensure long-term field reliability, the internal assembly utilizes PTFE seats and RPTFE packing, providing a bubble-tight seal and superior corrosion resistance. This Apollo GB-50 series valve is 100% factory tested and meets ANSI Z21.15 and CSA 9.1 standards for manually operated gas valves, rated for pressures from 1/2 PSI up to 5 PSI.

• High Thermal Capacity: Optimized for large-scale equipment with a rating of 3,144,000 BTU/hr.
• Integrated 1/4" Pilot Tap: Simplifies the installation of pilot lines or sensing equipment directly into the valve body.
• Space-Saving Design: The heavy-duty tee handle allows for easy operation in compact furnace or boiler enclosures.
• Industrial Construction: Features a chrome-plated brass ball and blowout-proof stem for enhanced safety and durability.
• Broad Media Compatibility: Suitable for natural gas, manufactured gas, liquefied petroleum, and LP gas-air mixtures.

• What is the maximum pressure rating for this gas valve? The 50-GB5-A1 is rated for gas pressures of 1/2 PSI and is tested for operation up to 5 psig in specific piping applications.
• Can the 1/4" NPT side tap be used for a pressure gauge? Yes, the 1/4" NPT tapping is designed to accommodate both pilot light connections and electronic pressure sensors or manual gauges.
• Is this valve suitable for outdoor installation? As a standard bronze gas shutoff valve, it is primarily intended for indoor gas piping between the meter and the appliance inlet.
