Description:

OUYI?TOP?ENTRY?BALL?VALVE?is?mainly?used?in?pipeline?and?industry?system?and?it?has?a?top?

entry?and?on?line?maintenance?function.It?has?a?lot?of?advantages,such?as?small?fluid?resistance,

simple?structure,small?volume,light?weight,reliable?saaling,convenience?for?operation?and?

maintenance,open?and?close?quickly,as?well?as?start?and?close?flexibly.

1.One?piece?body

One?piece?body?is?used?for?the?body?to?guarantee?sufficient?strength?and?rigidity?under?maximum?

rated?operating?pressure.The?internal?parts?of?valve?are?carefully?designed?and?selected?to?ensure

?reliability?under?all?kinds?of?operating?condition.Enough?margin?wall?thckness?and?adaptation?of?

high?strength?connective?bolts?are?convenient?for?valve?maitenance?and?sufficiency?to?support?the?

stress?from?piping.

2.Top?entry

Its?most?difference?from?common?ball?valve?is?that?its?maintenance?can?be?made?on?pipe?line?and?

without?dismounting?from?the?pipe?line.The?back?space?seat?structure?is?adopted?for?the?seat?and?

the?rear?portion?of?seat?retainer?is?oblique?angle?to?prevent?accumulation?of?impurity?from?affecting?

back?space?of?seat.

3.Low?operation?torque

OVIKO?top?entry?series?ball?valve?has?a?trunnion?mounted?ball,whose?surface?is?ground,polished?

and?hard?face?treated.The?ball?and?stem?is?integrated,sliding?bearing?is?installed?on?the?external?

bore?so?that?the?friction?radius?is?small?and?operation?torque?is?very?low.

4.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.

5.Reliable?sealing

The?seat?sealing?is?formed?by?seat?sealing?and?metal?retainer?component.The?seat?retainer?floats?

axially?and?low?pressure?sealing?of?valve?seat?is?reached?by?pre-pressure?of?spring.In?addition,the?

piston?effect?of?valve?seat?is?designed?reasonably,which?realized?high?pressure?sealing?by?the?

pressure?of?operating?medium?and?realize?the?interception?of?retainer?to?form?the?sealing?of?the?body.

The?expansion?graphite?ring?is?designed?to?realize?sealing?under?fire?condition.

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.Anti-static?and?fire?safe?design

The?fire?prevention?design?of?valve?meets?the?requirement?in?API6FA/API607?standard?and?the?design?

of?the?anti-static?conforms?to?regulations?in?API6D?and?BS5351.

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.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?

We?can?also?produce?according?to?customer\'s?size.
