MATERIALS
It’s all about the glass!
Borosilicate is a type of glass with silica and
boron trioxide as the main glass forming ingredients.
Tempered glass is about four times stronger than
"ordinary," or annealed, glass.

AFTER MOUNTING, INSTALLING, RETORQUE…
▀ THE GAGE GLASS SHOULD BE BROUGHT INTO
SERVICE SLOWLY. TO AVOID EXCESSIVE THERMAL SHOCK
OR MECHANICAL STRESS ON THE GLASS OR CHAMBERS,
THE CONNECTING OR BLOCK VALVES MUST OPEN SLIGHTLY.
THE GAGE TEMPERATURE AND PRESSURE ARE THEN
ALLOWED TO SLOWLY EQUALIZE WITH THE VESSEL.
▀ THE GAGE VALVES SHOULD BE PARTIALLY OPENED BY 1/2”
TURN TO PREVENT THE BALL CHECK FROM CHECKING
AT THE SEAT. THIS WILL ALLOW THE GAGE GLASS TO FILL
WITH LIQUID. UPON READINESS, THE VALVE MUST BE FULLY
OPENED TO ACTIVATE THE AUTOMATIC BALL CHECKS.
