 Handling Precautions
High Performance Butterfly Valves Rotary Control Valves
Installation Instructions
• For rotary control valves (including butterfly valves), basically
the rotation of the disc alters the area of the flow path and
thereby controls the flow. Therefore, unlike globe valves, if an
elbow or tee is placed upstream from the valve, the valve is
directly affected by the disturbed flow and cavitation, noise,
vibration, or other problems result. In the worst case, this may
cause an imbalance of torque on the valve and result in
rendering the actuator ineffective. To avoid these problems,
install a straight pipe of a sufficient length (at least 6 to 8D) in
the valve up-and down-stream side, and carefully consider the
orientation of the valve to minimize the affect of drift. In addition,
when installing stop valves in front of and behind the valve,
leave a space of at least 6D in between.
• The concave side of the disc (the side with the stem exposed)
must face upstream.
• Do not use plastic pipes and loose flanges.
• When installing or removing the valve, keep the disc fully
closed.
• It is possible that seat leakage occur when fluid (e.g. powder
