Description:

FORGED?TRUNNION?BALL?VALVE

1.Forged?ball?valve?feature

OVIKO?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.

6.?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?loaded?pressure?in?the?center?

cavity?of?valve?can?be??released?to?low?pressure?end?by?self?relief?seat.

7.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.

8.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.

9.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.

10.Various?driving?types

The?top?pad?of?valve?designed?according?to?ISO?5211,which?is?convenient?for?connection?and?

exchange?of?various?drivers.The?common?driving?types?are?manual,electrical,pneumatic?and?

pneumatic/hydraulic.

Applications:

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