Description:

 

FORGED TRUNNION BALL VALVE

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.

 

 

 

Applications:

 

Large and medium oil, gas, water conservancy, pharmaceuticals,Chemical, heating equipment industry 

We can also produce according to customer's size.

 

 

 

Competitive Advantage:

 

1. Our advantages:

Top quality, as a result of specialization and standardization! In production, full automatic lines have 

been applied, such as CNC machinery etc.

Best price, as a result of direct selling! Direct selling is our marketing mode, so the clients can get
