Conbraco 20-207-00 Valves

The Conbraco 20-207-00 is an industrial-grade rough bronze water gauge set designed for reliable liquid level monitoring in high-pressure boiler and tank applications. Featuring 3/4" NPT male connections, this assembly is engineered for durability in demanding mechanical rooms. The unit includes a 3/4" OD x 16" standard glass tube, allowing for clear visibility of fluid levels. To ensure a leak-proof seal under thermal cycling, it utilizes high-grade EPDM glass seals and Teflon stem packing, which provides excellent chemical resistance and prevents stem leakage. The aluminum type wheel allows for precise manual operation, even in high-heat environments. This water level gauge is rated for 200 PSI at 400°F or 400 PSI at 100°F, making it a standard choice for technicians maintaining steam systems or pressure vessels requiring Apollo valves water gauge components. Its heavy-duty bronze construction ensures long-term resistance to corrosion and mechanical stress.

• High-Pressure Tolerance: Rated for 400 PSI at 100°F, providing a significant safety margin for standard boiler sight glass applications.
• Robust Material Build: Rough bronze body construction resists de-zincification and environmental degradation in mechanical spaces.
• Thermal Stability: Equipped with Teflon packing and EPDM seals to maintain integrity during constant temperature fluctuations.
• Easily Serviceable: The standard 16-inch glass length and NPT connections allow for straightforward field replacement and maintenance.

What is the maximum operating temperature for the Conbraco 20-207-00?
This unit is rated for a maximum temperature of 400°F at a reduced pressure of 200 PSI.

Does this gauge set include the glass and guard rods?
This specific model includes the 16-inch standard glass tube; however, technicians should verify if additional guard rods are required by local boiler codes for their specific installation.

Is the Teflon stem packing compatible with treated boiler water?
Yes, the Teflon packing is highly resistant to the chemicals and pH adjusters typically found in closed-loop steam and hydronic systems.
