Description:

FORGED TRUNNION BALL VALVE(DBB)

1. Forged ball valve feature

OUYI 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.

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.
