Description:
FULL WELDED BALL VALVE
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. 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.
