INSTALLATION / OPERATION INSTRUCTIONS

GENERAL DESCRIPTION

Kenco Flat Glass Gauge Valves are simple, rugged instruments engineered and constructed throughout to give you
accurate liquid level readings for the life of the vessel. We offer a complete range of valves suitable for most applications.
Like any instrument, Kenco gauge valves must be installed, operated, and maintained with reasonable care and due
regard for the application, and the environment.

INSPECTION & DELIVERY

Upon receiving the valves, check all components carefully for damage incurred in shipping. Notify the shipping company
immediately of any such damage, and request a damage inspection. Confirm that the valve model number and
pressure/temperature ratings (located on the nameplate) match the application conditions. Also, confirm that the valve
materials are compatible with the process media and the environmental conditions.

CAUTION – Kenco valves are not to be used with lethal substances as defined by ASME Section VIII.

BEFORE YOU INSTALL THE GAUGE VALVES
Consider the following:

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

• 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.

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.
