Pig Valve also named as pig launcher valve or pig ball valve,Pig Valve is a newly type device for
pig launching or receiving and have the two position shut-off ball valve function.use pig valve to
launching or receiving pig would more easily accomplished pipeline cleaning,emptying, separating
and sequential transportation of medium.the pig valve can completely replace the complex
conventional pig launcher and receiver system,which core is launching or receiving barrel.
Compared with conventional pig launching and receiving device
1. Pig Valve is much more preference in compact structure.
2. Stable performance,easy operation,easy to installation and maintenance.
3. Lower purchase cost and running cost.
These advantages make pig valve a preferred solution to limited space such as offshore platform.
Type
1.Separating pig valve is mainly used for separating or sequencing transport medium,the area
of ball bore is approx.3% larger than the flow area of pipe.and the receiving valve has an additional
seal so as to prevent with certainty any mixing of the media to be separated after the pig has arrived.
Thus ensure the good separating effect.Separating pig valve is a preferred solution to protect the
internal floating tank from damaged by gas flow to tank when pigging.
2.Bypass pig valve is a pig valve with bypass,two elliptical flow channels have been provided in
the valve ball, and are in the perpendicular direction to the ball bore,the cross section of the
bypass is approx.25% of the pipe,this ensure delivery flow not be interrupted when receive or
launch pig (valve in closed position).
3.Cleaning pig valve is the standard pig valve,the area of ball bore which is approx.25% larger
than the flow area of pipe to keep the continuous flow during pigging.cleaning pig valve can be
use as the shut off valve.
