G e n e r a l i n fo r ma 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 ty i n s tr u c t i o n s :
•
Read installation instructions thoroughly. Failure
to comply can result in device failure, system
damage or personal injury.
•
According to EN 13313 this product is intended
for use by personnel having the appropriate
knowledge and skill.
•
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 fluids without prior approval
of EMERSON. Use of fluids not listed could result
in Change of hazard category of product and
consequently change of conformity assessment
requirement for product in accordance with
European Pressure Equipment Directive
2014/68/EU.
•
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
M o u n t i n g l o c a t i o n :
•
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.
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.
•
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 ng :
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 and consider 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. body temperature of 120°C!
•
To avoid overheating it is advised to make the joint at
one end cool the device completely before repeating
the 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 ur 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.
Warning:
•
Failure to do so could result in loss of refrigerant
and personal injury.
•
The pressure test must be conducted by skilled
personnel with due respect regarding the danger
related to pressure.
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
of external joints. The allowable leakage rate must be
according system manufacturer’s specification.
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.
Note: 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 de 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.
