Conbraco 20-205-00 Valve

The Conbraco 20-205-00 is an industrial-grade heavy pattern bronze water gauge set engineered for high-pressure liquid level verification in boiler and process piping systems. Designed for demanding HVACR environments, this assembly features a 1/2" NPT male connection and a robust rough bronze body that ensures long-term structural integrity. This specific configuration includes a 5/8" OD x 12" length standard glass tube, secured by durable EPDM glass seals and high-performance Teflon (PTFE) stem packing to prevent leakage under thermal cycling. The unit is equipped with a composite plastic wheel for manual isolation and is rigorously rated for 200 PSI at 400??F and up to 400 PSI at 100??F. For the service technician, the 20-200 series heavy pattern design provides a thicker wall section than standard sets, making it a reliable choice for high-service boiler water level monitoring and industrial sight glass applications. Each set includes essential coated steel guard rods and a 1/4" needle drain valve for simplified maintenance and blow-down procedures.

• Enhanced Durability: Heavy pattern bronze construction provides superior resistance to mechanical stress and corrosion in thermal systems.
• Secure Sealing: Integration of Teflon stem packing and EPDM seals offers high-temperature chemical compatibility and leak prevention.
• Complete Assembly: Includes top and bottom valves, 12-inch sight glass, and steel guard rods for immediate field installation.
• Precise Level Monitoring: The 5/8" OD glass allows for clear visual inspection of liquid levels in pressurized vessels.

Common Questions

What is the maximum pressure rating for the Conbraco 20-205-00?
This gauge is rated for 400 PSI at 100??F and 200 PSI at 400??F. Always verify that your glass tube and gaskets are also rated for the intended operating pressure and temperature.

Does this unit include automatic ball checks?
The 20-205-00 is a non-automatic model. For applications requiring automatic shut-off in the event of glass breakage, refer to the 20-250 series equivalents.

What maintenance is required for these sight glass valves?
Technicians should perform daily visual inspections for glass thinning or erosion. Use the integrated 1/4" needle drain valve to blow down the gauge regularly to prevent sediment buildup.
