Conbraco 24-652-03 Gauge Valves

The Conbraco 24-652-03 is a specialist-grade rough bronze liquid level gauge valve engineered for critical fluid monitoring in industrial boiler systems and storage vessels. Featuring 3/4 inch NPT male connections, this heavy-duty gauge set is built for high-performance thermal environments, providing a pressure rating of 500 PSI at 100°F and maintaining 250 PSI at 400°F. The chain operation assembly is designed for overhead installations, allowing technicians to actuate the 12-foot chain lever from the floor level for safety and convenience.

For enhanced system protection, the Apollo 24-652-03 incorporates automatic ball checks. In the event of sight glass breakage, these internal checks seat immediately to prevent hazardous fluid loss. The PTFE with Hypalon glass seal and braided PTFE with Aramid stem packing ensure superior leak resistance and chemical compatibility across varied media. This unit is intended for professional HVACR and boiler installation where reliable water level gauge monitoring is required.

Key Benefits

• Effective safety shut-off provided by integrated automatic ball checks to prevent boiling water or steam discharge.
• Optimized for high-reach applications with a standard chain lever for remote valve actuation.
• Exceptional durability via ASTM B584 bronze construction, resisting corrosion and mechanical stress.
• High-temperature integrity through Aramid-reinforced PTFE packing, minimizing maintenance cycles.
• Compatible with 3/4 inch OD gauge glass for clear visibility of liquid levels in pressurized tanks.

Common Questions

Does this gauge valve include the sight glass and guard rods?
No, the Conbraco 24-652-03 is a "less glass and rod" model. It includes the top and bottom valves and the chain mechanism. The 3/4" OD glass and protective rods must be sourced separately based on your specific center-to-center requirements.

What is the maximum temperature rating for this bronze gauge set?
The hardware is rated for service up to 400°F at 250 PSI. Always ensure your selected boiler sight glass and gaskets are rated to match these thermal and pressure specifications.

Can this be used for steam boiler applications?
Yes, the rough bronze construction and automatic ball checks make it suitable for steam duty, provided the installation complies with local codes regarding glass shielding and vessel pressure.
