Product Introduction
Developed from existing forged steel 3PC trunnion
mounted ball valves, Pig ball valves for launching and receiving are a good
alternative for conventional systems for pig cleaning because of the compact
structure, which also has the fireproof and anti-static device. The valves are
widely used in oil and gas pipelines to cut or connect the pipeline and clean
the pipeline to improve the efficiency of pipeline transportation.

Application Scenarios
-Clean the new installed pipe internal residue
prior first commissioning
-Internal pipe wall anti-rust and
corrosion-resistant coating
-Pipe regular maintenance to removal of liquid,
wax and general cleaning
-Isolation and transition of differential working
media in same pipe
Product
Features
-Double O ring sealing to prevent the
leakage from stem area.
-Secondary metal-metal sealing perform when
non-metal sealing is damaged.
-Double O ring sealing plug with two
pressure-relieve holes to easy & safe the operation on the field.
-Trunnion mounted ball design to extent
seat life and reduce the torque of operation.
-Emergency seat sealant injection fitting
to stop leakage from the seat.
-Isolated pig chamber to eliminate the
requirement for additional shut-off valve.
-Energized wave spring seats to ensure the
sealing even at low pressure.
Working
Sequences
Pig Launching-Clockwise to close
Step 1-Open position -Through conduit flow,
no pockets to trap wax or debris.
Step 2-Close valve -Upstream and downstream
is sealed off. Vent body cavity pressure.
Step 3-Remove entry plug -Insert pig into valve
ball cavity.
Step 4-Screw entry plug into place -Close
vent valve.
Step 5- Open valve -Flowline pressure moves
the pig downstream.
Pig Receiving-Clockwise to close
Step 1-Open position -Through conduit flow
stopper in valve cavity arrests pig.
Step 2-Close valve -Upstream and downstream
is sealed off. Vent body cavity pressure.
Step 3-Remove entry plug -Remove pig from valve
ball cavity.
Step 4-Screw entry plug into place -Close
vent valve.
Step 5- Open valve -Flow brings the net pig
along to be trapped.

FAQ
Q: What is pig valve?
A: Pig valve, normally consists of Pig Launching
and Pig Receiving valve, is a device to clean the internal pipe periodically,
and it is especially widely used in Oil & Gas pipeline industry.
Q: What’s the feature of your Pig Launcher and Receiver
Valve?
A: Our pig valves are developed from our existing
series forged steel 3PC trunnion mounted ball valves, and have the function of
launching or receiving pig as well as all the natural function of standard pipe
line ball valves.
