VAL-MATIC'S 2"-24" SERIES 4700
QUADROSPHERE BALL VALVE
OPERATION, MAINTENANCE AND INSTALLATION
INTRODUCTION
The Series 4700 QuadroSphere®Ball Valve has
been designed to provide long trouble-free
operation. This manual will provide you with the
information to properly install and maintain the valve
to ensure a long service life. The valve is a trunnion
mounted quarter-turn valve capable of handling a
wide variety of liquid media with high solids content.
The Size, Flange, Working Pressure, Working
Temperature, and Model No. are stamped on the
nameplate for reference.
RECEIVING AND STORAGE
Inspect valves upon receipt for damage in shipment.
Unload all valves carefully to the ground without
dropping. Do not lift valves with slings or chains
around the actuator or through the seat area. Extra
care must be taken when handling electric motor
and cylinder actuated valves. Valves should remain
crated, clean and dry until installed to prevent
weather related damage. Remove end protector
and thoroughly inspect interior of the valve and
end flange sealing surfaces for damage or foreign
objects.
For long-term storage greater than six months,
indoor storage is recommended. When in storage,
the valve should be kept in the fully open position
unless it has been fitted with a fail-to-close actuator.
Operate the valve from fully closed to fully open and
back to fully closed at least once every 12 months.
Following long-term storage, valves should be
inspected prior to use.
INSTALLATION
Prior to installation, personnel should familiarize
themselves with hazards of pipeline media and
potential emissions. Read all applicable directions
and instructions prior to any installation,
maintenance or troubleshooting. Check valve
identification against operation requirements before
installation. Ensure that the actuator has been
installed properly and is functional. Observe ball bore
position to ensure valve opens fully. Confirm the
position of
the QuadroSphere ball's flat-face to
e nsure its spherical lip surfaces are in full contact
with seat when fully closed. Place the valve in its fully
open position to prevent damage to the
QuadroSphere ball during installation.
Install valve in system using proper size and type of
mating flanges and appropriate gaskets for RF, or
seal rings for RTJ. Flow can be in either direction.
QuadroSphere ball valves may
be installed in
any orientation. Note: Whenever possible, if the
valve is being installed in a horizontal line, it is
good practice to have the stem horizontal so the
bottom of the ball rotates
downstream to allow for the
full effect of the self-cleaning QuadroSphere
seating technology. If necessary based on pipeline
start-up operations, actuate the valve to its fully
open position.
DESCRIPTION OF OPERATION
QuadroSphere ball valves are designed for on-off
service, but may be used to throttle flow in certain
conditions and applications. Contact the factory
before using the valve for throttling or flow control.
The QuadroSphere valve is a quarter-turn ball valve
intended to operate through a 90-degree rotation
with the use of a handle or handwheel & worm gear
actuator. The QuadroSphere may also be actuated
using an electric or hydraulic / pneumatic cylinder
actuator.
Normal actuation is accomplished by rotating the
handwheel o r l e v e r clockwise
to close and
counterclockwise to open. The concentricity of
the
seats and trunnion mounted QuadroSphere
ball
· will allow for the ball to be rotated 180
degrees. Use caution to insure that the soft seat
inserts are fully retained in seat rings before turning
ball through
or beyond its original 90 degree setting.
Exact closed and open positions may be
determined with respect to the centerline of the bore
through the ball by observing the stem keyway.
When the key slot
is perpendicular to the flow
path through the valve (not in-line with the pipe) it
is closed.

3
Block and Bleed
The standard configuration of the QuadroSphere
trunnion ball valve is a double block and bleed
(DBB) design. The seats are floating and are
activated by internal springs and line pressure to
seal against the QuadroSphere ball. The seats work
independently and if pressure in the body cavity
exceeds the upstream or downstream pressure, the
cavity pressure will relieve itself to the side of lower
pressure.
This single piston effect allows for verification of the
effectiveness of the seats while the valve is installed.
Use caution when purging, venting or draining the
valve’s center cavity. With the valve closed and the
upstream and/or downstream end pressurized,
carefully open the vent valve or drain valve on the
center cavity. Continue venting until the center
cavity reaches atmospheric pressure. Once the
center cavity reaches atmospheric pressure, the
seat integrity may be determined by observing for
additional leakage through the open vent. If no
additional leakage appears through the vent, the
seats are sealing affectively.
QuadroSphere ball valves provided with a Double
Isolation and Bleed (DIB) configuration will not
automatically relieve center cavity pressure. These
valves are provided with an automatic cavity
pressure relieve device. Caution should be taken to
ensure the pressure relief device is functioning
properly and there is no excess pressure in the
center cavity.
MAINTENANCE
Once the QuadroSphere valve has been put into
service, the valve shall be checked and maintained
periodically. Routine inspections should look for
worn sealing surfaces, aging of packing rings and
“O” rings, and corrosion of the body. If these
conditions are observed, the valve shall be repaired
or replaced. It is suggested that inspection and
maintenance of the valve be performed every three
months for installations where the fluid is water or
oil. Inspections should be performed at least every
month where the fluid is a strong corrosive.
Prior to performing any maintenance on the
QuadroSphere ball valve, ensure all pressure is
relieved from the valve, including the center cavity.
When performing repair or maintenance operations,
do not attempt to remove the gear/lever, remove or
attempt to replace bolts and nuts when the valve is
under pressure. Replacement O-rings, gaskets,
bolts and nuts should be of the same sizes and
materials as the original ones. Valve O-rings and
gaskets should be ordered as spare parts for
maintenance and replacement. After the
replacement of any O-ring, gasket, bolt and nut, the
valve shall be closure tested prior to reuse.
No weld repair of any valve component should be
performed on an installed valve. Repairing of any
pressure containing part by the user is not
recommended. If pressure containing parts become
worn due to extended service or harsh service, the
valve should be replaced.
Lubrication
QuadroSphere ball valves do not require stem or
seat lubrication for standard operation. An
emergency sealant injection system is provided on all 6
NPS and larger QuadroSphere Ball Valves with single
piston (DBB) design. Sealant injection should only be
utilized
in emergency situations where seat insert(s)
have been damaged by foreign matter or high
temperatures.
Seat Injection: For best results, sealant
injection should only be performed with the valve
in the full open or full closed position.
Stem Injection: Stem seals are permanent and
sealant should only be injected for temporary or
emergency sealing.
Lubrication of Seat Rings: In certain applications it
may be advantageous
to periodically lubricate
behind the seat rings to prevent the ingress of
foreign particles and/or build-up of scale, etc.
General purpose grease should be used, such as
Mystic JT-6, or equal. Heavier greases should
not
be used.
TROUBLESHOOTING
Table 1 lists several maintenance techniques for
common operating issues with ball valves. Table 1
is not meant to be an exhaustive list of all problems
that can occur with a ball valve. Rather, it presents
a starting point for the user to consider when
performing maintenance.

VALVE CONSTRUCTION
As shown in Figures 1, 2 and 3 and Tables 2-4, the
QuadroSphere ball valve is a trunnion mounted
design, consisting of a three-piece forged body,
plated ball, and stems that rotate in bearings. The
valve is designed to handle flow in either direction.
The valve is available in NPS 2 through 24 in ASME
pressure classes 150# through 2500#. It is suitable
for water, steam, oil or other fluids depending upon
materials of construction.
Valves are designed and tested to API 6D and
ASME B16.34 with either carbon steel or stainless
steel construction. Typical materials of construction
are listed in Figures 1, 2 and 3. Optional bolting is
available to meet either NACE MR0103 or NACE
MR0175.
