Conbraco 20-601-03 Gauge Valves

The Conbraco 20-601-03 Gauge Valves are engineered for high-visibility liquid level monitoring in demanding industrial boiler applications and vessel management. This rough bronze water gauge set features a 1/2" NPT male connection and is designed as a "less glass and rod" configuration, allowing for custom tailoring to specific site requirements. Forged from high-grade ASTM B584 bronze, these chain lever water gauges utilize a quarter-turn valve stem operation, facilitating rapid isolation during maintenance or emergencies. The EPDM glass seal and Teflon stem packing ensure a leak-proof interface, even under significant thermal cycling. Rated for 250 PSI at 400F and 500 PSI at 100F, this Apollo Valves 20-601-03 assembly is a reliable choice for process piping and steam service. The 12-foot chain-operated lever ensures that technicians can safely operate the liquid level indicator from the floor, maximizing ergonomic safety and operational efficiency.

• Enhanced Safety: Includes 12 feet of chain and an H-2485 pull handle for remote operation of overhead boiler water gauges.
• High-Temperature Durability: Equipped with PTFE stem packing and EPDM gaskets to withstand steam boiler environments up to 400F.
• Efficient Isolation: Quarter-turn stem design allows for immediate flow shut-off, facilitating faster glass replacement and maintenance.
• Robust Construction: Heavy-duty rough bronze body provides superior resistance to corrosion and mechanical stress in HVACR systems.
• Application Versatility: Standard 1/2" MNPT connections ensure compatibility with a wide range of industrial tanks and pressure vessels.

What glass size is required for the Conbraco 20-601-03?
This specific model is the "less glass and rod" version of the 20-601 series. It is designed to accommodate standard 5/8" OD gauge glass. Length should be determined by the center-to-center distance of your specific installation.

Can I use this valve for petroleum-based fluids?
While the bronze body and Teflon packing are highly resistant, the standard EPDM glass seals are generally not recommended for petroleum service. For oil-based applications, consider swapping to Viton or graphite gaskets.

Is this a non-automatic or automatic water gauge?
The 20-601-03 is a non-automatic gauge valve, meaning it does not contain ball checks. It is primarily used when manual control and unrestricted flow for level reading are prioritized over automatic shut-off features.
