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.
