CAST FLOATING BALL VALVE
 
Detailed Description
 


A. Locking device.
B.Fire safe and static design.
C. Lower operation torque.
1.Bow-out proof stem
 
For the purpose of preventing the stem from flying off  resulting in abnormal rising of the inner pressure of valve,shoulder is fixed at the lower part of the stem.In addition,in order to prevent leakage resulting from burnout of packing set of the stem in a fire,thrust bearing is set at the contact position of the shoulder at lower part of the stem and valve body.Thus an inverse seal seat is formed which will prevent leakage and avoid accident.
 
2.Key lock
 
Locks can be used to lock the manual valve when  it is fully open or closed so as to prevent non-working personnel from pulling the handle which may result in misoperation of valve.It can also avoid opening or closing of valve resulting from the shock from pipelines or unpredictable factors that may cause an accident.For working pipelines such as combustible and explosive oil,gas and chemical medium,or for field piping site,the locking mechanism is especially useful.
 
3.Anti-fire safe design
 
When the trunnion ball valve be used normally,its sealed by seat and ball surface,seat retainer sealed by O-ring and body,this is soft sealed and reliable sealing.When the seat and O-ring are burnt,the seat retainer and body will be sealed by expanded graphite.Thus act anti-fire safe purpose.
 
4.Anti-static device
 
In order to prevent friction among ball,stem and PTFE that generates static electricity which may light the combustibles and explosives that cause an accident,in this ball valve,static-conduction spring is set between the stem and the ball,the stem and the body.Thus static electricity is conducted to ground and system safety is secured.
 
5.Low torque in operation
 
The self-lubricated bearings are installed at the friction of stem,resulting in wear resistance,fiexibility of operation and low torque.
 
6.Automatic body cavity relief
 
When the body pressure going up un-normally as the unstable factor,the trunnion ball valve downstream seat will be pushed by un-normally pressure,and the release the un-normally pressure automatically,it doesn??t damage to the sealing of upstream seat.The unnormal pressure which in the floating ball valve body will release the pressure into the upstream pipe directly,it doesn't damage to the sealing of the downstream seat.
 
7.Various driving types
 
The top pad of valve designed according to ISO 5211,which is convenient for connection and exchange of various drivers.The common driving types are manual,electrical,pneumatic and pneumatic/hydraulic.
