A.valve feature
ZHONGCHENG 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.
 
B.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.
 
C..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.
 
D.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.
 
E.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.
