Tubular Liquid Level Gauges

Tubular Liquid Level Gauges are designed to view liquid levels using clear or red line Borosilicate tube to observe liquid levels. All valves use a stuffing box configuration to seal the glass tube, and have a ball check shutoff to prevent loss of vessel contents in case of glass failure. Operating pressure and temperatures are subject to the limitations of the tubular gauge glass and washer composition.

Body material:304SS,316SS,Bronze,etc

Sealing:Rubber,etc

Glass tube:Borosilicate glass,clear or reline.

Protective tube:Stainless steel or bronze

Connections:1/2’’ or 3/4’’ male NPT.

These valve bodies are rated for 500 PSIG at 450F. The actual pressure limitations are of the wall thickness of the glass tube,at the same time the work temperature is the other factors of influence of pressure. These sets are usable with oils and petrochemical liquids. Use with water or steam is not recommended due to the possibility of the steel valves developing rust or corrosion.

The following pressure values are for industry standard high pressure gage glass use. The steam services values are for reference only. For actual steam service, choose stainless steel valves.
