With the continuous innovation of natural gas pipeline valves, while traditional pipeline valves continue to function, many valves with new structures and new functions are gradually applied to natural gas pipelines.
In the future development of pipeline valves, the pipeline ball valve will continue to be the main force of pipeline valves with its own advantages; the plug valve will be used as a supplementary cut-off valve in the natural gas pipeline and station control system. Special valves for special requirements; flat valves will be mainly used in pipelines for transporting crude oil and refined oil and natural gas pipelines with pressures exceeding CL900~2500Lb; and forced sealing valves will be used as a special valve. More and more used in metering systems, In metering and calibration systems, multi-pipe mixing systems, tank isolation and frequently operated systems.
2. Valve design and manufacturing characteristics
