Pig valve, normally consists of Pig Launching & Pig Receiving valve, is a device to clean the internal pipe periodically, and it is especially widely used in Oil & Gas pipeline industry. Neway series pig valves are developed from our existing series BS 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. This field-tested pig valve offers Design durability and reliability service for oil and gas applications to improve the piping transportation efficiency. It can easily and safely use most of popular pig styles, either One-Piece Molded Pigs or Spherical Pigs that are intended for use in pig ball valves. Finished Pig Valve Main Application: Clean the new installed pipe internal residue prior first commissioning. Internal pipe wall anti-rust and corrosion-resistant coating. Application Pipe regular maintenance to removal of liquid, wax and general cleaning. Isolation and transition of differential working media in same pipe. Application 3

Pig Launching - Clockwise To Close Pig Receiving - Clockwise To Close Step 1 Open position Step 1 Open position Through conduit flow no pockets to trap wax or debris. OPEN OPEN Through conduit flow stopper in valve cavity arrests pig. Step 2 Step 2 Close valve. Close valve. Upstream and downstream is sealed off. Vent body cavity pressure. CLOSE CLOSE Upstream and downstream is sealed off. Vent body cavity pressure. Step 3 Step 3 Remove entry plug. Remove entry plug. Insert pig into valve ball cavity. Remove pig from valve ball cavity. CLOSE CLOSE Step 4 Step 4 Screw entry plug into place. Close vent valve. CLOSE CLOSE Screw entry plug into place. Close vent valve. Step 5 Step 5 Open valve. Open valve. Flowline pressure moves the pig downstream. OPEN OPEN Flow brings the net pig along to be trapped. 6
