Conbraco Industries 20-350-03 Water Gauge Valve Overview
The Conbraco Industries 20-350-03 is a heavy-duty rough bronze water gauge valve engineered for reliable performance in demanding hydronic and steam system applications. Featuring 1/2″ NPT male connections, this valve is built to deliver accurate gauge readings while protecting system integrity through integrated automatic ball checks that isolate the gauge in the event of a line break or gauge failure.
Key Features
- 1/2″ NPT male connections for straightforward installation into standard piping systems
- Rough bronze body construction for excellent corrosion resistance and long service life
- Automatic ball checks that instantly shut off flow if the gauge is removed or fails, preventing system pressure loss
- EPDM glass seal provides a reliable, leak-free seal between the gauge glass and valve body
- Teflon stem packing ensures smooth operation and minimizes the risk of stem leakage over time
- Aluminum type handwheel for easy manual operation
Pressure & Temperature Ratings
- Rated at 200 PSI @ 400°F — suitable for high-temperature steam and hot water applications
- Rated at 400 PSI @ 100°F — ideal for higher-pressure, lower-temperature water service
Typical Applications
- Boiler water gauge connections
- Steam and hot water heating systems
- Hydronic system pressure monitoring points
