Ball valve advantages

Ball valve: It evolved from the plug valve. Its opening and closing part is a sphere, which is used to rotate 90° around the axis of the valve stem to open and close. Ball valves are mainly used on pipelines to cut off, distribute and change the flow direction of media. Ball valves designed with V-shaped openings also have good flow regulation functions.

advantage:

①Has low flow resistance (actually 0);

② Because it will not get stuck when working (when there is no lubricant), it can be reliably used in corrosive media and low-boiling point liquids;

③ Achieving perfect sealing within a larger pressure and temperature range;

④ Rapid opening and closing can be achieved. The opening and closing time of some structures is only 0.05~0.1s to ensure that it can be used in the automation system of the test bench. When opening and closing the valve quickly, there is no impact in the operation;

⑤The spherical closing piece can be automatically positioned at the boundary position;

⑥The working medium is reliably sealed on both sides;

⑦ When fully open and fully closed, the sealing surface of the ball and valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface;⑧With compact structure and light weight, it can be considered as a reasonable valve structure for low-temperature medium systems;

⑨ The valve body is symmetrical, especially the welded valve body structure, which can withstand the stress from the pipeline well;

⑩The closing parts can withstand the high pressure difference during closing. ⑾The ball valve with a fully welded body can be buried directly underground so that the valve internal parts are not corroded and has a long service life of up to 30 years. It is an ideal valve for oil and natural gas pipelines.
