Conbraco 50-303-02 Valve

In the field, reliability is non-negotiable, and the Conbraco 50-303-02 Valve is a staple for high-capacity burner gas control valves. This 3/4" female NPT manual gas shutoff valve is engineered for precision and durability in commercial and residential heating systems. Constructed with a heavy-duty bronze gas cock body and featuring a stainless steel spring trim, it is built to withstand rigorous use while maintaining a secure seal. This industrial-grade gas valve offers a massive flow capacity of up to 1,310,000 BTU/hr, making it a preferred choice for HVAC burner manifold setups and large-scale boiler applications. The "X" handle position provides clear visual confirmation of the valve status, while the dual 1/8" NPT pilot tappings on both sides—shipped with one side plugged—offer the versatility needed for pressure testing and pilot lines in complex mechanical rooms.

• High BTU Capacity: Rated for up to 1,310,000 BTU/hr at 1/2 PSI, ensuring performance for high-demand gas appliance installation.
• Versatile Tapping: Dual 1/8" NPT tappings allow for convenient manifold pressure gauge attachment or pilot line connection from either side.
• ASTM Bronze Construction: Robust bronze body and stainless steel internal springs provide superior corrosion resistance for main burner gas control.
• Temperature Resilience: Certified for operation in environments ranging from 32° to 125°F, compliant with ANSI Z21.15 and CSA 9.1 standards.

What is the maximum pressure rating for this valve?
The Apollo Conbraco 50-303-02 is CSA design-certified for a maximum operating pressure of 1/2 PSI. However, the unit is factory-tested at 10 PSIG to ensure structural integrity and leak-free performance during initial system commissioning.

Can I use this valve for propane (LP) applications?
Yes, this bronze manual gas valve is suitable for use with natural, manufactured, mixed, and liquefied petroleum (LP) gases, provided the BTU requirements and pressure limits are maintained.

Is this valve suitable for lead-free potable water systems?
No, this is a dedicated 3/4 inch gas shutoff valve designed specifically for fuel gas piping. It is not intended for use in potable water delivery systems.
