INSTALLATION
Storage of Butterfly Valve Assemblies
• Assemblies must be stored indoors, protected from the
elements.
• Materials received on job sites that have long
installation lead times should receive extra protection
from construction damage.
• Resilient seats must be protected from abrasion,
cutting and nicking, as this will damage the liner and
may cause flange area leaks.
• Electric actuators cannot be stored in wet, damp or
caustic areas.
• Do not store construction material on top of valve
assemblies.
Installation Practices
• VR series butterfly valves are designed to be installed
between ANSI 125/150 flat-faced, raised face, slip-on
or weld neck flanges.
• Valve should be installed a minimum of 10 pipe
diameters from upstream or downstream elbows,
strainers, pumps, etc.
• For chilled water, condenser water or hot water
applications, the valve should be installed with the
stem in a vertical orientation, with the actuator
mounted above the valve.
• For applications in which there is a possibility of
sediment in the flow, the valve should be installed with
the stem in a horizontal position and the bottom of the
disc should close FROM the downstream side, rather
than from the upstream side.

• Make sure the flange faces are clean and free of rust,
scale and debris to prevent damage to the liner face.
• Do NOT use flange gaskets on VR series butterfly
valves. (Fig. 23)
• Follow the recommended flange bolting sequence. (Fig.
32)
Installation using Welded Flanges
• Mount flanges on both sides of valve body and install
bolts to properly align valve body and both flanges.
• Install the valve with the disc in the "Almost Closed"
position (Fig. 22)
• Do not use any flange gaskets (Fig. 23)
• Make sure the valve liner and flange internal diameters
are in alignment. (Fig. 24)
• Take valve body / flange pair assembly and align with
piping ends.
