V. Handling and Storage
VI. Pre-installation and Mounting
Do not subject valves
to impact.
Always keep valve in
an upright position.
Pressure relief valves should be stored in a dry environment and protected
from the weather. They should not be removed from the skids or crates until
immediately prior to installation. Flange protectors and sealing plugs should
remain installed until just prior to installation.
Pressure relief valves, either crated or uncrated, should never be subjected to
sharp impact. This would be most likely to occur by bumping or dropping during
loading or unloading from a truck or while moving with a power conveyor, such
as a fork lift truck. The valve, either crated or uncrated, should always be kept
with the inlet down (i.e., never laid on its side), to prevent misalignment and
damage to internal components. Even crated valves should always be lifted
with the inlet down.
Uncrated valves should be moved or hoisted by wrapping a chain or sling
around the discharge neck, then around the upper yoke structure, in such
manner as will ensure the valve is in a vertical position during lift. Never lift
the full weight of the valve by the pilot assembly, tubing, lifting lever or other
external device.
When a valve is uncrated and the flange protectors removed, prior to
installation, meticulous care should be exercised to prevent dirt from entering
the outlet port.
While hoisting a valve to the installation area, care should be exercised to
prevent bumping the valve against steel structures and other objects
Pressure relief valves should be mounted in a vertical, upright position.
Installing a valve in any other position will adversely affect its operating in
varying degrees as a result of induced misalignment of parts.
Flanges and gasket surfaces must be free from dirt and debris when valves are
installed. Flange bolts should be tightened evenly to prevent distortion of the
valve body and inlet nozzle. Before start-up be sure all threaded points are tight
and secure.
Prevent dirt from
entering the outlet or
inlet port.
