Emerson ALCO CONTROLS BVE Serie Manual De Instrucciones

G e n e r a l i n f o r m a t i o n :
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.
S a f e t y i n s t r u c t i o n s :
• Read operating instructions thoroughly. Failure to
comply can result in device failure, system damage or
personal injury.
• This product is intended for use by qualified personnel
having the appropriate knowledge and skills like trained
according to EN 13313 or a specific training for
flammable refrigerants.
• Flammable refrigerants require special handling and
care due to its flammability. Sufficient ventilation is
required during service of the system. Contact with
rapidly expanding gases can cause frostbite and eye
damage. Proper protective equipment (gloves, eye
protection, etc.) has to be used.
• Ensure that the system is correctly labeled with applied
refrigerant type and a warning for explosion risk.
• In a severely contaminated system, avoid breathing acid
vapors and avoid contact with skin from contaminated
refrigerant / lubricants. Failure to do so could result in
injury.
• Before opening any system make sure pressure in
system is brought to and remains at atmospheric
pressure.
• Do not release any refrigerant into the atmosphere!
• Do not exceed the specified maximum ratings for
pressure and temperature.
• Do not use any other fluid media without prior approval
of EMERSON. Use of fluids not listed could result in:
- Change of hazard category
consequently change of conformity assessment
requirement for product in accordance with European
Pressure Equipment Directive 2014/68/EU.
• Ensure that design, installation and operation comply
with European and national standards/regulations.
• For flammable refrigerants only use valves and
accessories approved for it!
• 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.

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.
I n s t a l l a t i o n :
• Do not remove seal caps until ready for installation in
order to minimize entering of moisture and dirt.
• WARNING: Avoid damaging the connections!
• For BVS version do not mount schrader valve and cap
before brazing.
• For installing the Schrader valve core use torque 0.4 –
0.5 Nm. Standard torque tool for Schrader valve should
be used.
• For panel mounting see dimension of holes in Fig. 4.
B r a z i n g : ( F i g . 1 )
WARNING:
Ensure valve is in the fully open position before brazing
(see Fig. 2a). Failure to do so could cause damage to
internal components.
• Perform the brazing joint as per EN 14324.
• Before and after brazing clean tubing and brazing joints.
• Minimize vibrations in the piping lines by appropriate
solutions.
• To avoid oxidization, it is advised to purge the system with
an inert gas such as nitrogen while brazing.
• Do not exceed the max. surface temperature of
+120 °C!
• To avoid overheating it is advised to make the joint at one
end cool the device completely before repeating the
of product and
procedure on the other end connection.
• For BVS version install schrader valve and schrader valve
cap after cooling down of the ball valve.
P r e s s u r e T e s t :
After completion of installation, a pressure test must be
carried out as follows:
- according to EN 378 for systems which must comply with
European pressure equipment directive 2014/68/EU.
- to maximum working pressure of system for other
applications.
T i g h t n e s s T e s t :
Conduct a tightness test according to EN 378-2 with
appropriate equipment and method to identify leakages
from joints and products. The allowable leakage rate must
BVE- / BVS-... ≤ 28 mm (DN < 25)
1/4" (6 mm) ... 1-1/8" (28 mm)
–40°C ... +120°C (short term +150° C) / –40°F ... +250°F (short term +300°F)

be according system manufacturer's specification.
WARNING:
• Failure to pressure test or tightness test as described
could result in loss of refrigerant, damage to property
and/or personal injury.
• The tests must be conducted by skilled personnel
with due respect regarding the danger related to
pressure.
O p e r a t i o n :
• 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.
WARNING:
Never leave the ball position as shown in Fig. 2c
otherwise seat leakage can occur.
• To avoid operation by unauthorized 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.
D e s i g n c o n s i d e r a t i o n :
• 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/ASHRAE 15 for the
charges refrigerant. After charging mark Unit with
refrigerant type and oil type.
• For use with refrigerant listed in CAN/CSA B52,
ANSI/ASHRAE 34. After charging mark Unit with
refrigerant type and oil type.
S e r v i c e / M a i n t e n a n c e :
• Before any debrazing ensure that the flammable
refrigerant is pumped out of the system and the room
around the system is well vented so no refrigerant left.
• According
maintenance, tightness tests shall be carried out at the
relevant part of the refrigerating system. This shall apply
where appropriate following any repair.
