Replacement for R05
General information:
The BVE/BVS series of Bi-directional Ball valves
are designed for general use in isolating suction,
discharge and liquid line pipe-work during
maintenance shutdown periods.
•
For further information, see technical data sheet
BVE_35066.
Safety instructions:
•
Read installation instructions thoroughly.
Failure to comply can result in device failure,
system damage or personal injury.
•
It is intended for use by persons having the
appropriate knowledge and skill. Before
attempting to install the valve, make sure
pressure in system is brought to and remains at
atmospheric pressure.
•
Do not release any refrigerant into the
atmosphere.
•
Do not use any other fluid media without prior
approval of Emerson. Use of fluid not listed
could result in change of hazard category of
product and consequently change of conformity

Ball Valves Series BVE / BVS
Operating Instructions
Mounting location:
•
The BVE/BVS valve may be installed in any
position which allows access to remove the stem
cap. The valves are bi-directional.
•
Locate the BVE/BVS as close as possible to the
section of pipe-work to be isolated. This will reduce
the amount of refrigerant to be recovered during
future maintenance of the system.
Installation:
•
Do not remove seal caps until ready for
installation. The seal caps should be removed with
care to avoid damaging the connections.
•
For BVS version do not mount schraeder valve
and cap before brazing.
•
Ensure valve is in the fully open position before
brazing (see Fig. 2a). Failure to do so could cause
damage to internal components.
•
To avoid oxidization, it is advised to purge the
system with an inert gas such as nitrogen while
brazing.
•
When brazing, direct the flame away from the
main body of the valve to avoid possible internal
damage. Use wet rags or other suitable heat
protection (see Fig. 1). On larger body sizes it may
be necessary to re-humidify wet rags with
additional water during brazing process!
To avoid overheating the valve body, it is advised to
make the joint at one end and cool the valve
completely before repeating the procedure on the
other end connection.
For BVS version install schraeder valve and
schraeder valve cap after cooling down of the ball
valve.
For panel mounting see dimension of holes in Fig. 4.
