Quality Gauge & Valve Series Q-TB40FL Model

The “Steam Line” TB40FL units are designed for steam service to 2000WSP. These Gages can be used as Direct Reading Sight Glass for boilers in compliance with A.S.M.E. PG-60. Visible ranges are achieved by using multiple sections with a minimum 1” overlap to ensure continuous visibility. The gage chamber is full width, and reinforced with internal tie bars to add durability to the product, and remove the possibility of lateral deflection, which can cause early gasket failure. All units are supplied with recessed gasket seats and forged covers which allow for easy and inexpensive maintenance.
