Safety valves should be stored in a dry environment
to protect them 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.
Safety 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 internals. 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 insure that the valve is in vertical position during
lift, (i.e., not lifted in horizontal position). Never lift the
full weight of the valve by the lifting lever. Never hook
to the spring to lift. When safety valves are uncrated
and the flange protectors removed, immediately prior
to installation, meticulous care should be exercised to
prevent dirt from entering the outlet port while bolting
in place.
While hoisting to the installation, care should be
exercised to prevent bumping the valve against steel
structures and other objects.
Do not lift valve
horizontally, or hook to
lifting lever or spring.
Prevent dirt from
entering valve outlet
port.
Handle valve carefully.
Do not drop or strike.
VI. Storage and Handling Prior to Installation
The “safety valve” is the final safeguard between a
controlled boiler and a catastrophic explosion. In an
over-pressure situation, the pressure in the valve
inlet increases until the force on the disc exerted by
the system pressure equals the force exerted by the
spring. This causes the safety valve to pop, or lift,
relieving the excess steam until the system pressure is
reduced to the desired level.
The Consolidated Safety Valve has been a leader
in the industry since 1879, thus offering over a
century of experience in design, engineering and
product manufacture. ’s history of dependable and
reliable valve service assures that today’s products
and designs are consistent with industry’s current
requirements. Rigid manufacturing standards
controlled by an ASME approved Quality Control
Program insure that each valve will be manufactured
in accordance with established design criteria and
tested for functional performance. This quality
controlled manufacturing and test program assures
that each valve manufactured will provide long and
reliable service.
