A Release with Ball Valve

November 4, 2021

A baseball valve, invented in the 1950s, is really a valve with a spherical disc. With the rapid development of technology and the ceaseless improvement of processing technique and product structure, the ball valve has been one sort of main valves in recent years. Now it’s applied having an increasing speed at home and abroad. The ball valve is widely used in different industries, such as petroleum refining, long-distance transport pipes, chemical, paper making, pharmacy, water treatment system, electricity and so on.

A baseball valve, one form of quarter turn valve, is quite literally a baseball placed in a passageway whereby fluid flows. The ball features a hole, by which the valve opens and closes. When the ball lies this way where the hole runs exactly the same direction as the passageway, the fluid simply flows through the hole, and the valve is open. However, once the ball lies this way where the hole is perpendicular to the passageway, the fluid cannot pass through, and the valve is closed. The ball is controlled from outside of the valve, often with a handle that can be turned 90 degrees, or a fraction turn https://linquip.com/industrial-directories/341/ball-valve, back and forth for opening and closing the valve. Therefore, ball valve is a superb selection for shutoff applications.

But with the development of technology, in addition, it has got the functions of throttling-control and fluid-control.

The ball valve has the following main features. What comes first is that the it’s very versatile because it supports pressures around 700 bars and temperatures around 200°C and sizes typically range between 0.5 cm to 30 cm. secondly, the ball valve has such a simple structure it is easy to use and repair.

Thirdly, the seal and the ball tend to be in close state so the ball valve is extremely reliable and not easy to be eroded by the working medium. Last although not least, with the PTFE valve seat ring the ball valve is quite durable and usually work to achieve perfect shutoff even after years of disuse. Are you aware that types, you can find five general body types of ball valves: single body, three-piece body, split body, top entry, and welded. The difference among them is based on how a pieces of the valve-especially the casing that contains the ball itself-are manufactured and assembled. The valve operation is exactly the same in each case.
