Reflex Water Level Gauge Assembly
Model 480 Reflex has a single vision slot on one side of the chamber in which light can enter to determine liquid level. Above the liquid level, glass prisms reflect the surrounding light giving typically a silvery appearance. Below the level, the liquid fills the prisms causing the glass to become relatively transparent giving a typically dark appearance.
The offset and straight pattern valves isolate the gauge chamber from the liquid contents of the vessel.
Offset valves have an advantage of permitting the inside of the gauge glass to be cleaned easily with a minimum of disassembly. By removing the 1/2" vent and drain plug, a straight passage through the gauge chamber is opened. A brush can be inserted through the valve vent and drain for glass cleaning.
Both upper and lower valves in each set are equipped with horizontal ball checks. Balls are located on the vessel side of the valve seat.
Valves with ball checks omitted meet ASME boiler requirements, the lower valve is available with an optional vertical rising ball check located in the offset portion of the valve body, and the upper valve has a leaky seat.
