Gas Pipeline Ball Valve
Key Specifications / Features
The Ball Valves for gas pipeline service are designed and tested in accordance with the American Petroleum Institute (API) specification 6D/ISO 14313, includes requirements for gate, ball, check and plug type valves.
All the gas pipeline ball valves are piggable design. The devices designed to clean or inspect the interior of the pipeline (the “pigs”) also may be passed through the bore of the valve without catching on a reduced bore or other interior projection in the valve.
Pipeline ball valves, which are trunnion style, are now making inroads in all types of pipeline service, particularly in natural gas.
Because the valves are to be buried they had to be fitted with extended stems for remote operation and the whole assembly had to be insulated using a special ecological coating which provides high corrosion protection as well as mechanical strength.
