Compliance Application of Double Isolation And Double Emission (DIB-2) Ball Valve in Refined Oil Pipeline.

Compliance advantages of DIB-2 ball valve in refined oil pipelines
Meeting API 6D standard
The DIB-2 ball valve strictly complies with the API 6D standard, which is a widely recognized international specification for pipeline valve design and manufacturing. API 6D imposes strict requirements on valve sealing performance, structural strength, material selection, etc., to ensure the reliability and safety of valves in high-pressure, high-temperature, and corrosive medium environments. The DIB-2 ball valve meets the requirements of double isolation and discharge in API 6D through double sealing surfaces and automatic pressure relief functions.

Zero leakage guarantee
During the transportation of refined oil pipelines, leakage may lead to serious environmental pollution and economic losses. The DIB-2 ball valve can achieve zero leakage even under extreme working conditions through double sealing surface design. Its sealing performance has been strictly tested and can effectively isolate the medium to ensure the tightness of the system.

Automatic pressure relief function
In refined oil pipelines, the expansion of the medium may cause the pressure in the valve chamber to increase, thereby posing a safety hazard. The self-pressure relief function of the DIB-2 ball valve can automatically discharge the pressure in the valve chamber to one side of the pipeline to avoid overpressure in the valve chamber and ensure the safe operation of the system.

Combination of bidirectional sealing and unidirectional sealing
The DIB-2 ball valve combines the advantages of bidirectional sealing and unidirectional sealing. Its inlet end adopts a double piston effect valve seat, and the outlet end adopts a self-draining valve seat, which can achieve unidirectional sealing on the basis of bidirectional sealing and further improve the safety of the system.
