Description
The High Performance Butterfly Valve is designed for on-off and throttling applications in the chemical,
power, paper, air conditioning, petroleum and refining industries.
A choice of body styles, ratings, seat and packing options, materials, actuators and accessories is
available in valve sizes from 2
–54" (50–1350mm). Pressure and temperature ratings are shown on the
valve data plate.
Handling
Lifting the valve improperly may damage it. Do not fasten lifting devices to the
actuator, disc or through
the seat opening in the body. Lift the valve with
slings, chains or cables fastened around the valve
body, or fastened to bolts or
rods through bolt holes in the flanges.
Installing Valve
Metric fasteners should not be used with ASME Class 150/300 bolt holes and flange bolt
patterns. If you use metric fasteners with ASME Class 150/300 bolt holes and flange bolt
patterns, it may lead to product failure, injury, and loss of life. DeZURIK Inc. disclaims all
liability associated with the use of metric fasteners with ASME Class 150/300 bolt holes and
flange patterns, including but not limited to personal injury, loss of life, loss of product,
production time, equipment, property damage, lost profits, consequential damages of any
kind and environment damage and/or cleanup. Use of metric fasteners with ASME Class
150/300 bolt holes and flange bolt patterns is a misuse that voids all warranties and
contractual assurances. If you use metric fasteners with ASME Class 150/300 bolt holes and
flange bolt patterns, you do so at your sole risk and any liability associated with such use
shall not be the responsibility of DeZURIK
, Inc. In addition to the foregoing, DeZURIK’s
Manufacturer’s Conditions apply.
Recommendations
Refer to the valve installation drawing for dimensional information.
Installing the valve in the wrong location may cause excessive dynamic torque and damage the
valve. When pipeline fluid velocities exceed 20 fps (6.0 m/s) for 12” (300mm) and smaller valves
or 12 fps (3.6 m/s) for 14” (350mm) and larger valves, it is recommended to install the valve at
least 8 diameters from the nearest upstream elbow or pump. For best performance results,
install valve shaft parallel with elbow or pump cross section (see image below). For more
specific installation recommendations, contact your local representative or DeZURIK for
assistance.
