General Information
BALL CARTRIDGE VALVE (BCV)
The Ball Cartridge Valve (BCV) is a quarter-turn valve with an offset ball and
a top entry cartridge design. The offset ball design provides bubble-tight
sealing capability at low pressures via mechanical loading of seals; this
sealing capability is enhanced at high pressures via pressure-energized
assistance. The camming action of the offset ball leads to a rapid decrease
of the mechanical loads on the seat, as the valve moves from the closed to
the open position.
The valve has bi-directional capability and can be designed to seal against
reverse flow. The internal components (seat, ball, seals, bearings, etc.) are
all contained in the cartridge assembly, and the parallel machined body
allows for easy installation/removal of the cartridge in the field. The valve
can be provided with the operators illustrated in Figures 1-3. Other options
are available upon request.
Storage
Inspect for any damage that may have occurred during shipment, prior to
storage. Contact your shipper immediately if damage is found. Valve flange
faces and/or butt-weld preparations are coated with rust inhibitor, then
covered with an impact barrier. Valves and actuation equipment should
be stored in the as-shipped condition indoors to protect them from harsh
environments including humidity and dust. Refer to the operator manual for
special long term storage requirements of actuation equipment.
Unpacking
Remove any shipping material and protective covers. Inspect the valve
internals for foreign object debris, then clean if necessary. Appropriate
handling equipment must be used when lifting the valve and actuator
assembly safely into position. Only use lifting points specified on supplied
Top Assembly drawing. Do not use actuator lifting points to lift the complete
valve and operator assembly. Pay attention so that slings or braces do not
damage the operator.
