Technical Bulletin B-100 Features Series 10

High Performance
Feature Butterfly valves
For Rating JIS 20K

General :
The series 10 butterfly valves has been developed for a large number of applications throughout process industries. The

series 10 high performance butterfly valves are mainly used for the control of fluids flowing in large valve at low differential

pressure. It offers added advantages such as simple structure and low cost.

Performance :

 High Cv to valve weight ratio compared to

conventional control valves.

 Throttling controls 60 rotation, on-off controls

90 rotation.
 Excellent control range ability.

Design Flexibility :

 Swing through and tight shut-off seated trim

design.

 Flange connection versions available.

 Full range of bonnet and packing design to suit

Various temperatures and fluids.

 Provides fire safe sealing, which combines a

soft seal ring and metal seal ring.

 Full range of body and vane material options,

With availability of hard facings.

Design Integrity : Figure 1. Series 10 Butterfly Valve

 Wafer type as standard.

 Triple eccentric mechanism.

 Actuator mounting flange dimensions in accordance

with ISO 5211/1-1977

The Evolution of Triple Offset Design

1. Single Offset

The center of rotation is moved back from the

centerline of the valve disc. The seat and Seal are

designed conically and on center, this design relies

on a frictional, interference seal and so it is applicable

only to soft-seated valves.

2. Double Offset

The center of rotation is moved from the

Centerline of the valve body. The seat and seal

Design remains frictional, interference seal, but

The length of rotation over which this friction occurs

Is reduced, allowing a larger range of process resistant

Seat materials to be used. However these materials

Must be relatively soft or highly elastic to prevent

“jamming”

3. Triple Offset

The centerline of the cone is rotated away from

The valve centerline resulting in an ellipsoidal profile

And providing the third offset. With this geometry,

Seat seal interference is completely eliminated

Ensuring long sealing life. The result is a torque

Seated, process pressure aided FRICTIONLESS

Seal. The geometry allows the body seat to be

Used as the closed limit stop, aiding operator

Adjustment. The Tripe Offset design is ideally

Suited to metal seated valves providing bubble-tight

Performance on high temperature, high pressure

And fire-safe applications.

THE TRIPLE OFFSET GEOMETRY

OFFSET 1 The shaft is offset behind the seat axis to allow complete sealing to contact around the entire seat.
OFFSET 2 The shaft centerline is offset from the pipe and valve which provides interference free opening and
Closing of the valves.

OFFSET 3 The seat cone axis offset from the shaft centerline to eliminate friction during closing and opening
And to achieve uniform compressive sealing around the entire seat.

 Triple offset and ellipsoidal sealing geometry

 Bi-directional bubble tight shut-off.
 Inherently Fire-safe by design.
 Developed geometry results in zero seat/seal friction
Low torques
Extended service life
Continued seal through thermal cycling torque seating
 Excellent flow and throttling characteristics covering services from
Cryogenic to high temperature
 Excellent control of fugitive emission by virtue of rotary stem movement and advanced
packing Materials
