Project Description

Pigging Valve

Camtech pig valves are robust in construction and are developed from our existing range of Trunnion mounted ball valves, and having the function of launching or receiving pig, as well as all the features and function of standard pipe line Trunnion mounted ball valves.
Pig valve, normally consists of Pig Launching & Pig Receiving feature, is a device to clean the internal pipe periodically, and it is widely used in Oil & Gas pipeline industry. These valves offer durability and reliable 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.


Available as a launcher and receiver.
Cost saving over conventional pigging systems.
Lesser joints and system components.
Complete range of fluid compatibility.
