Scope
®
The WKM
Triple Offset Valves are metal seated
butterfly valves. They are designed and manufactured in
a manner that allows the disc to rotate into and out of
the seat with absolutely no interference. This results in a
sealing system that does not depend upon interference
to achieve the seal like other butterfly valves.
Storage
After assembly and test, WKM
are placed in the closed position. Carbon steel valves
are painted on the external surfaces. Flange
protection is provided for all valves. Valves should be
stored in a clean, dry location. Outdoor storage is
permissible, but should be off the ground and
protected from the elements. For long term storage,
contact your Cameron representative.
Installation

Although WKM
Triple Offset Butterfly Valves have bi-
directional sealing capabilities and will operate in any
position,
the
following
recommended.
Flow direction
It is preferred to install the valve in the flow direction
as indicated by the arrow on the valve body. The best
sealing performance will be maintained even when
pressure acts on the non-preferred side of the valve,
however it is recommended to install the valve in the
direction of the flow arrow when the service tightness
requirements are more stringent in one specific
direction (Figure 1).

WKM
Triple Offset Butterfly Valves perform equally well
with the shaft in the vertical or horizontal position. Cameron
recommends that the optimum valve installation is with the
shaft in the horizontal plane.
Installing the valve with the shaft at an angle will minimize
any problem associated with solid particles present in the
fluid that otherwise could deposit in the lower bearing area.
