Characteristics of quick opening ball valves:

The quick opening ball valve evolved from the plug valve, and its opening and closing parts act as a ball, using the ball to rotate 90 ° around the axis of the valve stem to achieve the purpose of opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the direction of medium flow. Ball valves designed with V-shaped openings also have good flow regulation functions.

(1) Has good flow resistance (actual flow resistance is zero).

(2) Due to not getting stuck during operation (in the absence of lubricants), it can be reliably applied to corrosive media and low boiling point liquids.

(3) It can achieve complete sealing within a large pressure and temperature range.

(4) It can achieve fast opening and closing, and the opening and closing time of some structures is only 0.05-0.1 seconds to ensure that it can be used in the automation system of the test bench. There is no impact during quick opening and closing of the valve.

(5) The spherical closure element can automatically locate at the boundary position.

What is the principle and characteristics of quick opening of ball valves?

(6) The working medium is reliably sealed on both sides.

(7) When fully open and fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface.

(8) The compact structure and light weight make it 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.

(10) The closing element can withstand the high pressure difference during closing.

(11) The ball valve with a fully welded valve body can be directly buried underground, preventing the internal parts of the valve from being corroded. Its service life can reach 30 years, making it an ideal valve for oil and natural gas pipelines.
