Ball Valve
Ball Valve/ 3 pieces
Ball Valve/ Top entry
Spherical Disk Valve
1. The spherical disc rotates 90
degrees out of the material
flow to allow mass-flow
through it's full port.
2. The under-cut disc segment
provides clearance that
prevents powder jamming
between the disc and
housing.
3. The spherical disc wipes the
material away from the
matching radius of the the
seat to provide sanitary
sealing and longer seat life

Valve Classification
There are two groups to classify the valves:
1 – According to ANSI
ANSI = American National Standards Association
2- According to DIN

How do you select the valve ?
You have to Know :
1- Medium : Water , oil , Gas , Vapor…
2- Condition service : Working pressure , Working
temperature ,
3 – Size of line
4 – Type of connection : BW ,SW , RF , RTJ , FF ,
Male & Female ..
5 – What is the target : Open-Close , controlling
Example ?
1- Medium : Crude oil – Carbon steel ( WCB )
2- Service Condition : WP = 22 Kg/cm2 ,WT= 150
C degree ,
ASA = ?
3 – Size of line : 6"
(6 " )
4 – Type of connection : RF
5 – What is the target : Open-Close= Gate valve
Pressure & Temperature/ANSI B16.34
Pressure & Temperature/ANS B16.34
The technical specification is:
-Cast steel , Gate Valve , Flanged ends , Rising Stem , ( OS & Y)
Materials : According to ASTM –
- A216 Gr WCB
-Trim materials ( Stem , gate , seat
ring ) Cr 13%
- Size 6" , Class 300 , ( ASA 300 ,
300 Lbs , ANSI 300 )
- Manual Operation .

Flanged Ends :
Face to Face = F to F
Butt- weld Ends :
End to End = E to E
L,L2=F to F , L1=E to E

Type of Interfacing
Flat Face ( FF )
Type of Interfacing
Ring Type Joint ( RTJ )
Most common flange types
Length of Bolt
The Stud Bolt theoretical 
length can be calculated
by means of the
formula: L = 2 (s + n + h +
rf) + g
 s = free threads (equals 1/3
time bolt diameter)
 n = nut height (equals
nominal bolt diameter)
 h = flange (plate) thickness
 rf = height of raised face
 g = gasket thickness
