Bulletin V-BV2FH
The Series BV2FH Two-Piece Stainless Steel Flange Ball Valve is
designed to meet ANSI B16.34 flange standards and features ANSI 150#
flanged ends for easy installation. The valve features a stem design
providing additional protection against blow outs and RTFE seats and
seals for extended life. An ISO 5211 mounting pad accepts direct
mounting of pneumatic and electric actuators. All sizes allow for
maximum flow rates with minimal pressure drops. The Series BV2FH
body, ends, and ball have increased performance from the 316 SS
construction.
OPERATIONS
Manual Operations-To open or close the valve, turn the handle 90° (1/4
turn). Valve in OPEN position: the handle is parallel (in line) with the valve
pipeline. Valve in CLOSED position: the handle is perpendicular
(crossed) with the valve or pipeline.
Automated Operation-Valves with actuators should be checked for
stem alignment. Most applications are direct mount to the actuator,
greatly reducing any sideload or increased torque. Make sure that all
insert adapters are properly placed on the valve stem and fully engaged
in the actuator.
INSTALLATION
General Information for On-Site Installation-The valve may be fitted in
any position in the pipeline. For automated operation, W.E. Anderson
recommends that the valve and actuator be installed vertically in case of
valve leakage, although this is not necessary for proper operation of the
valve. Prior to installation, inspect valve and pipe ends to make sure they
are free from debris. Materials trapped inside the valve can cause
damage to the seats and result in leakage. The flow may be in either
direction of the valve. It is recommended to use expanded PTFE or
rubber gasket on a flat-faced flange. Flange bolts should be used and
evenly torqued using a torque wrench.

MAINTENANCE
This valve is designed for applications requiring ease of cleaning and
maintenance.
To disassemble:
First, make sure the valve is isolated from both process media and
pressure. Rotate the valve several times to relieve any pressure
contained in the ball cavity. Then loosen the four bolts and separate the
two pieces.
To re-assemble:
Tighten all bolts in a “star” pattern to ensure even compression. See Bolt
Torques table for proper assembly bolt torque. Rotate the valve handle
several times to check for free travel.
WARRANTY
The Series BV2FH warranties from defects in materials and
workmanship are covered for (1) year from the date of purchase. In the
unlikely event the valve should fail, the unit can be returned to the factory
for warranty repair if the warranty period has not expired. Be sure to
include a brief description of the problem plus any relevant application
notes. Contact our customer service department for an RGA number and
to set up the return.
