Construction and Design Features

Document No.：KE-1075-01 Sheet:2/31
Ⅰ Construction and Design Features
1. Construction and Design Features
1.1 The typical valve design is as illustrated below.
1.2 The rotation of the stem by 90°fully opens or closes of the valve.
1.3 Valves are serviceable only in fully open or closed position.
1.4 The ball is supported by two ball seats placed in the valve body and insert.
The upstream pressure pushes the ball, which compresses the down stream side ball seat
to completely shut off the fluid flow.
1.5 Fluid can flow through valve port in both directions.
This illustration represents a typical construction.

Ⅰ Construction and Design Features
2. Design Features
2.1 Uni-body, End entry design
The valve is uni-body and end entry floating ball valves with one-piece body, which
completely eliminates concern of fugitive emission through valve body joints.
2.2 Firesafe provision
KITZ ball valves can be optionally provided with graphite packing and body to insert flange
gaskets for use in the areas of production facilities where external leakage may be caused
by plant fires. These graphite components will contain the line media where PTFE or other
lesser materials may burn away, feeding fuel increasing the magnitude of the fire. KITZ ball
valves provided with graphite sealing components are identified as the SUPER-FIRESAFE
version in our product catalogs.
The integral, secondary seats on the body and body-cap minimize internal leakage, when
resilient ball seats are deteriorated in case of a plant fire.
2.3 Anti-static provision
Anti-static devices are provided to ensure electrical continuity between ball, stem and body.
2.4 Valve application
This ball valve may be used on application where a bi-directional flow is needed.
2.5 Actuator Mounting Pads
ISO 5211 actuator mounting pad is integrally provided for uniformly simplified mounting of
any actuators provided with valve mounting flanges designed to ISO 5211 dimensional
requirement.
2.6 Low Fugitive Emission Feature
The surface of stem and stuffing box, and interface clearance of stem-to-gland bushing,
stem-to-body and gland-to-stuffing box are precision controlled on machining and assembly
for low emission service.

Document No.：KE-1075-01 Sheet:9/31
Ⅲ Transportation and Storage
2. Storage
2.1 Cautions for Safety
(1) DO NOT store valves in a corrosive environment, which may cause corrosion
on threaded portions of valves.
(2) DO NOT remove protective covers until installation.
This will prevent the intrusion of any foreign object which could cause
damage to the closure elements such as ball and seats.
(3) DO NOT place any other objects on valves, and DO NOT step on them.
Overloading may damage valves.
(4) DO NOT carelessly pile up products to avoid risk of product damage and
personal injury caused by unstable piling.
(5) Keep the valves in the open position during storage. Storing the valves in
halfway position may deform the ball seats, leading to the internal leakage.
2.2 Storage
2.2.1 Storage valves at a dust-free, least humid and well ventilated places.
Indoor storage is recommended.
2.2.2 Storage of valves directly on the ground or concrete floor is not recommended.
2.2.3 Take appropriate measures to prevent valves from direct exposure to dust, rain and
sunlight, if valves should be stored outdoors.

CHAPTER Ⅳ
Valve Installation

Document No.：KE-1075-01 Sheet:11/31
Ⅳ Valve Installation
1. Flange Type
1.1 Cautions for Safety
(1) The sealing materials determine the characteristics of service fluid and
service range of pressure and temperature.
Check the valve specifications with the catalogs and/or the attached
nameplate.
Services beyond the valve specifications may cause fluid leakage and valve
malfunctions.
(2) DO NOT install valves in dead end service, which may result in external
leakage. In such a case use a blind flange to prevent the leakage.
(1) Keep a secure footing for valve installation and operation.
(2) Sufficient lighting should be prepared for valve operation.
(3) Piping should be properly supported, if needed.
1.1.1 Allow sufficient room for safe and easy operation, installation and subsequent
maintenance of valves.
1.1.2 For smooth operation, inspection and maintenance, take appropriate measures for
valves which are forced to be installed in small places.
1.1.3 Try not to install valves in the places where valve functions may be hampered by such
outer forces as vibrations and others.
1.1.4 It is recommended to install valves on horizontal piping in a upright position.

Document No.：KE-1075-01 Sheet:12/31
Ⅳ Valve Installation
1.2 Cautions for Safety
Keep off the valve lifting area to prevent personal injury caused by unsecured
valves.
(1) Take care not to catch fingers in flanges during mounting work.
(2) Take care not to damage flanges, ball and ball seats surfaces.
(3) Pipes should be properly supported, if needed.
(4) Retighten the gland bolts before operation. Packing compression may
become less due to the stress relaxation which may take place during
transportation and storage, leading to the occurrence of leakage through the
gland area.
(5) Be sure to insert new gaskets for valve mounting.

Document No.：KE-1075-01 Sheet:13/31
Ⅳ Valve Installation
1.2.1 Check the following items before valve mounting:
(1) Service conditions should be within the valve specifications.
(2) Valve flanges should correspond with piping flanges.
(3) Gasket contact surfaces of pipes and valve flanges must be thoroughly inspected to
make sure no scratch or any other indication of flaw is found.
(4) The appropriate length should be kept between pipe flanges for the valve face-to-face
dimensions including gasket thickness.
(5) The valve and pipe center should be aligned accurately.
(6) Bolt holes of flanges should be arranged symmetrically lined up against the center line
of flanges.
1.2.2 Before installation, the connecting pipes should be cleaned to remove any foreign object
such as sand, dust and welding spatters from the connecting pipe interior.
1.2.3 Handle valves carefully so that they may not fall or drop on the ground. Any
extraordinary mechanical impact should be avoided.
1.2.4 Remove flange covers from valves just before installation.
1.2.5 Check all threaded areas after installation and retighten them, if needed.
1.2.6 Piping should be flushed before test operation, with valves open, to assure removal of
any foreign object that could damage valves.
DO NOT operate valves during flushing.

Ⅳ Valve Installation
1.3 Installation Procedures
1.3.1 Make sure that pipes should be aligned accurately.
1.3.2 The length between piping flanges should correspond with the valve face-to-face
dimensions including gasket thickness.
1.3.3 Insert the valve between pipe flanges. Thread bolts through bottom bolt holes and
tighten bolts lightly.
1.3.4 Insert gaskets between valve and pipe flanges. It is recommended to apply the gasket
paste to gasket faces.
1.3.5 Make sure the correct alignment of gaskets, which are held by bottom bolts between
valve and pipe flanges.
1.3.6 Thread bolts through the other bolt holes and tighten them lightly.
1.3.7 Tighten bolts evenly, gradually and alternately in a star pattern as shown below.
The ends of all tightened bolts should protrude equally beyond the nuts.
1.3.8 Raise the line temperature and pressure gradually on test operation.
Retighten the threaded portions, if needed.

CHAPTER Ⅴ
Valve Operation

Document No.：KE-1075-01 Sheet:16/31
Ⅴ Valve Operation
1. Cautions for Safety
(1) DO NOT apply excessive torque by using a pipe or any other device to operate
the valve.
(2) DO NOT loosen bolts and nuts of gland and flange area of pressurized valves.
(3) Avoid the services in intermediate position for long period, which may damage
ball seats and cause seat leakage.
(4) Retighten the gland bolts and nuts before operation of the valve. Check a
handle torque while retightening the bolts and nuts so that the operation won’t
become too difficult due to over-tightening. The gland bolts should be
alternately tightened with an even force.
(5) Valve should be kept fully open during the line test or pressure test. The ball
seats may be deformed, if the valve is fully closed during test. Possible internal
though-bore leakage may occur under such conditions.
(6) When service temperature fluctuates, retighten the gland bolts and nuts after
the temperature is stabilized in preparation for the occurrence of stress
relaxation of the gland packing.
(7) Open the valve gradually to prevent damages of pipes, when the valve handles
high temperature fluid such as steam.
(8) Take appropriate measures to prevent freezing, as needed.
2. Operation
2.1 Lever handle
Rotation of the lever handle by 90°fully opens and fully closes the valve.
To close the valve, turn the operating handle clockwise according to the letters and the
mark indicating the direction. Counterclockwise rotation will open the valve.
2.2 Worm gear operator
According to the arrow or letter on the handwheel, turning the handwheel clockwise closes
