Storage
Valves Delivered by NUTRON
After valves are assembled and tested, they are placed in the full open position, flange seal surfaces and
bores are greased and end protectors are installed. This will provide adequate protection for indoor
storage. Extended outdoor storage or storage in particularly harsh environments (i.e. an uncovered
marine atmosphere) requires periodic inspection and the addition of a corrosion inhibitor. Contact your
NUTRON representative for extended storage guidelines. Valves should only be stored in the fully open
or fully closed position to prevent seat distortion.
Lifting and Handling Guidelines
Always use suitable lifting equipment and supports.
Make sure that devices (including but not limited to
lifting cranes, chains, or slings) are in good condition and
properly rated for the weight of the valve plus any
mounted actuation components before lifting loads.
Ensure that staff who take part in the lifting process have
sufficient training for the job. Participate in a pre-job
safety meeting or lift plan prior to any operation.
Establish red zones (no-go zones) prior to the lift.
Always secure the lifting to the valve body, never to the
actuator; otherwise, the stem/shaft may be damaged.
Before attaching the load, be aware of the weight of the
load to be lifted and locate the center of gravity to
prepare for how the load will behave and to ensure
balanced lifting. Lift the valve in the position in which
is it to be installed. Lift and move the load at an even pace to avoid swaying. Never leave the load
suspended in mid-air.
Make sure that the valve and actuator (if equipped) are correctly in place and secured prior to detaching
the supports. Make sure the load does not fall over when you undo the supports.
Refer to the packing list or product catalogue for specific valve weight
Refer to detail lifting drawings (available upon request) for specific weight and center of gravity.

Installation and Operation Instructions
Before Installation Safety Information
Valves shall be operated and maintained strictly in accordance with these procedures. Operation or
maintenance outside of these procedures constitutes abuse of the product and voids all warranty
claims.
When special operation is required, a formal written request to the company must be made for approval
to operate in this manner if warranty and product liability are to be maintained.
Before any work is performed on a valve, personnel working on the valve must obtain the proper work
permits required by their employer. Personnel shall always use safety precautions set forth by law and
the regulations required by their employer. Personnel shall also be aware that any venting or draining of
fluids from the valve shall be done in accordance with the safety and environmental procedures
enforced at the particular location where the valve is installed.
The maintenance personnel doing the repairs shall be well trained and familiar with all information
contained in this manual.
The valves shall be appropriately used for the intended purpose. Any safety or protection devices on the
valve shall not be permanently removed or altered unless written approval is received from a NUTRON
representative.
Transport, unpacking, lifting, and connections to the different types of systems (electric, pneumatic,
hydraulic systems, etc.) shall be made by expert and qualified personnel.
Should any difficulties or abnormalities arise that cannot be solved by the technician, contact a NUTRON
representative.
Any servicing not covered by these instructions must be made by an authorized service center, after
preliminary approval has been given by a NUTRON representative.
Installation
Before installation, ensure that all external components and sealing surfaces of connection flanges were
not damaged during transportation. Clearly identify the valve through its nameplate, check its weight
with the packing list or relevant documents, and then place it on a horizontal surface using suitable
handling equipment.
Handling equipment must be provided which is appropriate for the total weight of the package. Pay
particular attention that slings do not damage the gear or actuator, if equipped.
Do not use lifting lugs or eyes provided on the gear or actuator, if present, to lift the entire assembly.

To avoid the ingress of debris or sand into the ball and seat area, the protective covers should not be
removed until the valve is ready to be installed in the line. When the valve is ready to be installed in the
line, remove the protective plastic or wooden flange protectors.
During installation, the valve must be fully open and the line sections between which the valve will be
installed must be aligned, cleaned, and correctly spaced. Should the valve be closed, the exposed face of
the ball must be protected with grease or other anti-adhesive product.
320B3 ball valves may be installed in any position with flow from either direction. However, for best
service life there is a preferred vertical or horizontal position to maximize sealing and minimize the
accumulation of sediment. In the vertical position, it is preferred to have the upstream pressure from
above so the weight of the ball will assist the pressure in sealing. With the valve in a horizontal position,
it is preferred to have the stem lying horizontal (i.e. toward the viewer). During operation, flow will act
as a siphon and minimize retention of sediment.
When handling or installing a valve, keep the valve in the full open position whenever possible to
prevent foreign object damage to the ball. When installing the valve, allow for possible deformations
caused by the expansion of the line. The valve must not support the line. Avoid any strain in the valve
body.
When installing a valve with threaded ends
-Make sure the pipe threads that goes in the valve comply with ASME B1.20.1 or the standard
required on valve order. Do not use wear out threads, flat threads.
-Use pipe thread compound recommended for the application and temperature
-Torque the thread per recommended pipe thread standard. Do not over torque the thread.
When installing a valve with SW or BW ends
1. We do not provide weld procedure for welding valves inline, the customer shall be using his
approved procedure for specific materials to be welded, weld parameters, etc; and this
procedure should comply with API 6D/ BPVC Sec IX
2. We make sure the material of construction of the ends are clearly stamped on the valve
tailpiece (end connector) and on valve description and tag; and also the MTR shows the tailpiece
(end connector) heat treatment and mechanical properties
3. Please consult the customer drawing for the dimensional information’s needed
4. As far valve recommendations
a. The valve SW/ BW ends shall be cleaned from storage/ shipping grease or corrosion
inhibitor using a solvent
b. The valve shall be assembled and in fully open position as received.
c. The pipe shall be correctly aligned, and when welding in SW the pipe shall have a
minimum gap of 1/16”between pipe end and bottom of SW, as recommended by ASME
B16.11, to allow for pipe expansion

d. Make sure the temperature of body and seat pocket area, does not exceed 250F; check
with Tempil stick
e. To avoid excessive temperature electric welding equipment may be preferred over
oxygen-acetylene equipment. Also avoid rapid application of welding material by
limiting the welding rod size, e.g 1/8”or smaller based on pipe size, and allow to cool
down between each pass
f. Weld procedure that requires PWHT shall not be used unless the valves was ordered
with extended ends long enough to control body/ seat pocket temperature below 250F
g. Thoroughly clean weld debris by flushing before close the ball
CAUTION: Do not overload the valve beyond the design piping loads stated in the requirements.
CAUTION: While all 320B3 floating ball valves have self-relieving seats as standard equipment, it is
recommended that appropriate safeguards be put into place to prevent exceeding the
pressure/temperature limits given by the manufacturer.

Field Pressure Testing
When field pressure testing is required, follow these procedures to minimize any damage that could
occur to the sealing surfaces of the ball and seats:
1. Ensure that the test fluids contain corrosion inhibitors that are compatible with the valve
seat and seal material.
2. The valve should be in the fully open position when the injection of test fluid begins. This
will allow any pipeline debris to be flushed through the valve bore and out of the piping and
not damage the seat, seal, or ball.
3. Once the piping system has been purged of debris and the system has been filled
completely with the test fluid, the ball should then be turned to partially closed position
(approximately 10-30° from the fully open position), to allow test fluid into the body cavity
of the valve.
4. If performing line shell testing, the valve shall be in half open position. During a shell test is
the only time when the valve should ever be left in a position other than fully open or
closed. After shell test, return to the fully open or fully closed position for normal
operation. The maximum shell test line pressure can be 1-1/2 times the valve maximum cold
working pressure.
5. If performing seat testing, make sure the valve is fully closed. The maximum pressure for
seat testing is the maximum cold working pressure as stamped on the nameplate or as
appear on the description of sales documentation.
6. Upon completion of pressure testing all test fluids should be purged from the valve.
WARNING: If the ball is left for an extended period or is continually operated in any position other
than fully open or fully closed, excessive wear to the seat and ball will occur. This will result in
premature valve failure.
CAUTION: If the seats are tested to a higher pressure than the maximum cold working pressure, they
may become permanently damaged. The seat Maximum cold working pressure derived from the
Pressure-Temperature rating of the trim. If a higher test pressure is desired contact a NUTRON
representative for details.

Operation
320B3 series ball valves only work in the fully closed or fully open position; these valves work for on/off
service only.
WARNING: These valves shall never be operated partially open or partially closed. Throttling (partial
opening) or “pinching” flow may cause non-uniform wear on seats and ball over the sealing surfaces
where it is exposed to the flow line, preventing tight shut-off.
To close the valve, turn gear hand wheel clockwise until it stops; to open the valve turn the gear hand
wheel counter-clockwise until it stops.
All the wrench operated valves have the wrench levers aligned along with valve through bore when
opened and perpendicular with the through bore when closed.
All gear operated valves have the gear indicator aligned with the valve through bore when opened and
perpendicular with the through bore when closed. The gear also has “OPEN” and “CLOSE” markings.
While opening or closing, the ball must reseat; this reseating torque is higher than the run torque. Turn
the hand wheel until the gear has a positive stop.
If the valve is operated by a power actuator, carefully read the actuator operation manual.
CAUTION: The end stops have been shop set to assure the correct 90 degree rotation from the fully
open to fully closed position. Do not change their adjustment. If the valve is not correctly reseated at
the end of opening or closing, the ball and the seats can quickly be damaged when exposed to flow
pressure, preventing tight shut-off.
These valves can be operated by one person. It is recommended that no extensions be used for
operating the valve. Using an extension or power tool to operate the valve voids all warranty and claims,
and may result in failure.
Should maintenance be required, obtain the part number from the valve assembly nameplate and
contact your NUTRON representative.

Maintenance Procedures
Under normal working conditions, 320B3 ball valves are designed for lengthy, reliable service with very
little maintenance.
The only preventive maintenance recommended is to periodically inspect the valve for leaks around the
stem or actuator. Should a leak be noticed, the following procedure may be followed to adjust the
packing:
1. With the proper size wrench, tighten each of the two packing adjustment fasteners in a
clockwise direction.
2. Tighten each fastener an equal amount. Use the minimum torque required to stop the leak,
not to exceed the maximum torque value specified in Table 4 below.
3. Table 4 gives torque values that will affect a seal when the packing set is in good condition.
Torque values above this indicate that packing is worn and needs replacement. Excessive
tightening will cause an unacceptable increase in valve stem torque.
