Conbraco Industries 24-350-03 Valves

The Conbraco Industries 24-350-03 is a professional-grade liquid level gauge valve engineered for critical monitoring in high-pressure boiler and tank applications. Built with a heavy-duty rough bronze body, this set features 1/2" male NPT connections and is precision-machined to ensure reliable glass alignment and sealing. This model is equipped with automatic ball checks, a vital safety feature designed to prevent media loss if the gauge glass should break. To ensure a leak-free seal under thermal cycling, it utilizes PTFE with Hypalon glass seals and braided PTFE with Aramid stem packing. Rated for 500 PSI at 100°F and 250 PSI at 400°F, this direct reading liquid level gauge provides the thermal stability required for industrial steam and hot water systems. The aluminum type wheel offers a positive grip for manual isolation, making the 24-350-03 a standard choice for technicians focusing on ASME-compliant gauge valve installations.

Key Benefits

• Enhanced Safety: Integrated automatic ball checks shut off flow immediately if the gauge glass fails, protecting personnel and equipment.
• Chemical and Thermal Resistance: High-performance PTFE/Aramid packing and Hypalon glass seals provide superior durability against various boiler chemicals and high temperatures.
• Rugged Construction: The rough bronze metallurgy is specifically chosen for its resistance to dezincification and corrosion in pressurized water systems.
• High Pressure-Temperature Rating: Operates safely up to 250 PSI @ 400°F, making it suitable for standard ASME Power Boiler applications.
• Easy Operation: Lightweight aluminum handwheel allows for quick shut-off and manual throttling without binding.

Common Questions

What size gauge glass is compatible with the Conbraco 24-350-03?
This valve set is designed for use with standard 5/8" OD gauge glass. Ensure the glass length is correctly calculated based on your center-to-center distance for proper seating.

Are the ball checks required for all installations?
The automatic ball checks are a standard safety feature in the 24-300 series. They are highly recommended for pressurized vessels to prevent hazardous liquid or steam discharge during glass failure.

Can this valve be used for chemical storage tanks?
Yes, the bronze construction and PTFE seals provide excellent compatibility with many non-corrosive liquids, though you should verify compatibility with your specific media and the ASTM B62 bronze alloy.
