3 PC Forged Steel ball valve:
They are supplied for a broad range of applications in the power generation, chemical and petrochemical, oil and gas, pulp and paper,mining, and ship-building industries
A.Forged ball 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.
F. Double block&bleed(DBB)
When ball is full open or close position,the transmitter substance
in center cavity of body can be released by drainage and emptying
devices.In addition,the over lo
G.Emergency sealing
Compound injection holes are designed and compound injection valves
are installed at
locations of stem/cap and body support of side valve.When sealing of stem or seat is damaged to induce leakage,the compound can be used to do the second time sealing.A concealed check valve is installed in side of each compound injection valve to prevent compound from out flowing due to the action of transmitter substance.The top of the compound injection valve is the connector for fast connection with compound injection gun.
H.Extension stem
For the underground installed valve,the stem can be lengthened and
for the convenience of operation the corresponding compound
injection nozzle and drainage valve can be extended to the top of
valve.
I.Automatic body cavity relief
When the body pressure going up un-normally as the unstable
factor,the trunnion ball valve downstream seat will be pushed by
unnormal pressure,and the release the un-normally pressure
automatically,it doesn't damage to the sealing of upstream
seat.
J.Various driving types
The top pad of valve designed according to ISO ***1,which is
convenient for connection and exchange of various drivers.The
common driving types are manual,electrical,pneumatic and
pneumatic/hydraulic
