Conbraco 20-204-03 Valves

The Conbraco 20-204-03 is a commercial-grade water gauge valve set designed for precise fluid level monitoring in boiler and storage tank applications. Featuring 1/2" NPT male connections and a rough bronze body construction, these valves are built to withstand demanding mechanical environments. The integration of Teflon stem packing ensures leak-free operation and smooth torque during adjustment, while the EPDM glass seal provides a reliable high-temperature interface for standard gauge glass. Rated for 200 PSI at 400°F and up to 400 PSI at 100°F, this Apollo Valves 20-204-03 kit utilizes an aluminum wheel for manual shut-off control. As a standard bronze water gauge assembly, it is frequently specified for low-to-medium pressure steam systems where chemical compatibility and thermal expansion are primary concerns. This liquid level gauge valve configuration ensures technicians can perform maintenance or glass replacement safely by isolating the sight glass from the pressurized vessel.

• High-Pressure Performance: Rated for up to 400 PSI, making it suitable for a wide range of industrial fluid applications.
• Durable Construction: The rough bronze body and aluminum wheel offer superior corrosion resistance compared to lower-grade alloys.
• Superior Sealing: Equipped with Teflon packing and EPDM seals to prevent fugitive emissions and stem leaks.
• Standardized Fit: 1/2" NPT connections allow for straightforward integration into existing domestic and commercial boiler headers.

What type of gauge glass is compatible with the Conbraco 20-204-03?
This valve set is designed to accommodate standard 5/8" OD tubular glass. Always ensure the glass length is calculated correctly based on the center-to-center distance of the installed valves.

Can these valves be used for steam applications?
Yes, the 200 PSI at 400°F rating allows for use in various saturated steam environments, provided the system parameters do not exceed the specified thermal limits of the EPDM seals.

Is the stem packing adjustable?
Yes, the Teflon stem packing can be tightened to compensate for wear over time, ensuring a positive seal throughout the service life of the valve.
