Description:
 
FORGED TRUNNION BALL VALVE
1.Forged ball valve feature
OVIKO forged ball valve,the forging material can ensure sufficient rigidity and strength under 
maximum rated operation pressure  without inherent flaw of cast. Enough wall thikness of separate
body and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient
to bear the stress of pipe.The internal parts of valve are carefully designed and selected to ensure
reliability under all kinds of work condition.
 
2.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.
 
3.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.
 
4.Free leakage of body Sealed construction
The connective position of valve body and bonnet is double sealed by gasket and O-ring,on this 
base,such factors as fire,high temperature,shock and uneven opening or closing of the torque all 
can't induce external leakage.
