CHAPTER Ⅰ
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.

Valve Operation Device

Document No.：KE-1075-01 Sheet:5/31
Ⅱ Valve Operation Device
1. Lever Handle
1.1 The lever handle is directly mounted on the valve stem.
1.2 Rotation of the lever handle by 90°fully opens and fully closes the valve.
Turning the lever clockwise closes the valve, and turning the lever counterclockwise opens
the valve.

Ⅱ Valve Operating Device
2. Worm Gear Operator
2.1 The worm gear operator is mounted on the valve.
2.2 According to the arrow or letter on the handwheel, turning the handwheel clockwise closes
the valve, and turning the handwheel counterclockwise opens the valve.
2.3 Handwheel operating torque depends on the size and opening position.
2.4 Worm gear operator is to transmit a large torque to valve stems, converting a torque from
drive shaft by means of reduction gearing unit using worm gears.
