Emerson BVE Serie Betriebsanleitung

Ball Valves Series BVE / BVS
General information:
The BVE/BVS series of Bi-directional Ball valves
are designed for general use in isolating suction,
discharge and liquid line
maintenance shutdown periods.
• For further information, see technical data sheet
BVE_35066.
!
Safety instructions:
• Read
installation instructions
Failure to comply can result in device failure,
system damage or personal injury.
• It is intended for use by persons having the
appropriate knowledge
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
assessment requirement
accordance with European pressure equipment
directive 97/23/EC
• The attached strap (Fig. 3) contains important
valve data. Do not remove because of warranty
and traceability reasons.
• Do not connect on BVS Schrader connection
any safety pressure switches or other control
devices
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.

Operating Instructions
Installation:
• Do not remove seal caps until ready for
installation. The seal caps should be removed with
pipe-work during 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
thoroughly.
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
and skill. Before
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
for product in
valve.
• For panel mounting see dimension of holes in Fig. 4.
Leakage test:
• After completion of installation, a test pressure
must be carried out as follows:
- According to EN378 for systems which must
comply
directive 97/23/EC.
- To maximum working pressure of system for
other applications
Warning: Failure to do so could result in loss of
refrigerant.
Operation:
 The Valve has a built-in stop for the stem and
opening/closing of the valve is clearly indicated as
shown in Fig. 3. Open Valve is shown in Fig. 2a
and closed valve in Fig. 2b.
 Never leave the ball position as shown in Fig. 2c
otherwise seat leakage can occur.

To avoid operation
person's valve can be equipped with a
sealable cap which is available as accessory
(see fig. 5).
 The plastic cap is equipped with an O-Ring. Do
not use any tool to mount the cap. Cap must be
closed hand tight only.
Warning: If the valve is installed in hot gas
discharge line, the valve has hot surface temperature
during operation of system or short after off-cycle.
• The Design pressure marked on this component shall not
be less than the installed system working pressure or less
than the values outlined in ANSI/ASHARE 15 for the
charges refrigerant. After charging mark the installed
equipment with the refrigerant type and Oil used.
• For use with HFC and HCFC refrigerant listed in
CAN/CSA B52, ANSI/ASHARE

R-744 systems:
• This component can be used with a R744 (carbon
dioxide) , in either a secondary loop or a cascade
system where the design pressure of the
component is not less than the design pressure of
any of the associated components.
• This product does not have a pressure relief or
pressure regulating relief valve, so a sufficient
number of valves, either pressure relief or pressure
regulating relief valves, having the capacity
deemed adequate shall be field-installed on the
refrigerating system, and located such that no stop
valves is provided between the relief valves and
the parts or section of the system being protected..
Refer to the installation instructions provide with
the end use equipment manufacturer.
• When the refrigeration system is de-energized,
venting of the R744 through the pressure
regulating relief valves on the refrigeration system
can occur. In such cases, the system may need to
be recharged with R744, but in any case, the
pressure regulating relief valve(s) are not to be
defeated or capped. The relief setting shall not be
altered.
