Conbraco 50-703-02 Valve

The Conbraco 50-703-02 is a heavy-duty 2 inch NPT bronze gas cock engineered for high-capacity industrial and commercial gas service lines. Designed with a robust bronze body construction, this manual shut-off valve features a tee-handle (X handle) configuration for positive operation in tight mechanical spaces. The unit is equipped with 1/8" NPT pilot tappings on both sides, including a plug on one side, allowing for versatile field pressure monitoring or pilot line integration. With a maximum capacity rating of 7,300,000 BTU/hr, this main burner gas valve is optimized for low-pressure systems up to 1/2 PSI. It is commonly utilized in large-scale boiler manifolds and furnace applications where high flow rates and reliable isolation are non-negotiable. This Apollo/Conbraco gas valve ensures a secure seal and long-term durability in demanding HVACR environments, meeting the rigorous standards required for natural gas and propane systems.

Key Benefits

• High BTU Capacity: Rated for systems up to 7.3 million BTU/hr, making it suitable for industrial burner assemblies.
• Dual Pilot Taps: Features 1/8" NPT tappings on both sides for flexible pressure testing and pilot gas routing.
• Durable Bronze Housing: Resists corrosion and mechanical stress better than standard brass alternatives in commercial gas piping.
• Precise Flow Control: The X-handle design provides clear visual indication of valve position and ease of manual torque.

Common Questions

Can the Conbraco 50-703-02 be used for high-pressure gas mains?
No, this specific model is rated for low-pressure applications only, specifically up to 1/2 PSI. For higher pressure requirements, verify the specific AGA/CGA ratings of the assembly.

What is the purpose of the dual 1/8" NPT tappings?
These ports allow contractors to install a pressure gauge or connect a pilot line on either side of the valve body, providing installation flexibility depending on the piping layout.

Is this valve compatible with liquid propane (LP) gas?
Yes, the bronze construction and internal seating materials are compatible with both natural gas and propane vapor systems within its rated pressure and temperature range.
