Description:

CAST?FLOATING?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.Key?lock

Locks?can?be?used?to?lock?the?manual?valve?when?it?is?fully?open?or?closed?so?as?to?prevent?

non-working?personnel?from?pulling?the?handle?which?may?result?in?misoperation?of?valve.It?

can?also?avoid?opening?or?closing?of?valve?resulting?from?the?shock?from?pipelines?or?unpredictable?

factors?that?may?cause?an?accident.For?working?pipelines?such?as?combustible?and?explosive?oil,

gas?and?chemical?medium,or?for?field?piping?site,the?locking?mechanism?is?especially?useful.

3.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.

4.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.
