How do you identify upstream end of a ball valve?
in open condition the valve handle lever indicates the upstream end of a ball valveANS 2 - Most ball valves where that matters will have an arrow embossed on the valve body. In the case of many ball valve flow direction is immaterial.
What is the functional difference between a ball valve and a butterfly valve?
A ball valve is a ball with a hole through it that rotates around its axis to expose the hole for flow or the solid wall of the ball for no flow. The butterfly valve is a flat piece that is supported in the middle by a shaft that opens or closes when the shaft is rotated.

What's the difference between floating ball valve and fixed ball valve?
The ball ceramic valve evolved from the plug valve, in which there is a plug initially. The ball valves also can be divided into floating ball valve and fixed ball valve. The differences between floating ball valve and fixed ball valve are as follows. For the fixed ball valve, the ball is fixed and will not move even under pressure. There are floating valve seat to press the sing real tightly on the ball when suffering the media's pressure. Besides, the axletree is equipped with the stem connecting with the ball. The floating ball valve contains the ball floating inside. The structure is simple and has good tightness. When the media goes through, the pressure is passed into the seal rings, therefore the material of the seat rings should be well considered in design.

What is the structure of a ball valve?
Ball valves are quarter-turn on/off devices. A pivoting ball in the center of the valve controls the flow of liquid or gas media. The pivoting ball is known as a rotary ball, and it is designed with a hole (a bore) in the center. A stem on the top of the ball rotates the ball to open or close the valve. D Chel Valves are the Top Ball Valve Manufacturer in India.
