VALVE CONSTRUCTION
BEFORE YOU INSTALL THE GAUGE VALVES
Consider the following:
•
To avoid imposing piping strains on the valves, connect and mount the valves so that they do not support the
piping.
• Support brackets should be considered for gauges over four feet in length or over 100 pounds in weight,
especially when the gauge is exposed to vibration. These support brackets will prevent overloading the
connecting valves and piping and prevent damage to the gauge from excessive vibration.
• Always provide shutoff valves between the gauge and vessel. Kenco automatic ball check valves are
recommended to provide protection against physical injury and loss of product if glass breakage should occur.
These valves also provide a means to isolate the gauge for maintenance.
OPERATION
For protection during shipping, the packing gland is loosened and the stem is in the open position. Adjust the stem and
packing after installation. Do not tighten the packing any more than is needed to stop leakage. Slowly open the valves
carefully, and wait until the gauge is fully warmed up before completely opening the valves. Kenco
CAUTION – Rapid opening of connecting valves can cause glass breakage and / or possible injury to
personnel. Gauges should be brought into service slowly.
CAUTION – While the valves are in operation they must be in their fully open position. A partially open valve
will prevent the automatic ball checks from seating, which could result in physical injury to
personnel and loss of product.
