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.

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 are the working principles of ceramic ball valve?
The disc of ball valve is a ball, which rotates for 90 degree around the axis of the stem to realize the purpose of opening and closing. The function of ball valve is to cut, distribute or change the flow direction of medium. Ball valve not only has simple structure and good tightness, but also owns the lesser bulk, the lighter weight, and the less material cost. Besides, the ball valve is easily driven and operated to achieve the effect of rapid opening and closing. Therefore, the ball valve is one of the fastest developing valves varieties in the past dozens of years.
Is a ball valve a regulating valve?
no
What is a ball valve?
A ball valve is a contrivance by which a ball, placed in a circular cup with a hole in a bottom, operates as a valve.
A ball valve is used for what?

Is isolation valve similar to ball valve?
EXACTLY
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 trunnion ball valve?
Its a ball valve with a "mounted" ball. Basically, more durable, and more expensive. More torgue, higher pressure etc.
Structure of the tricuspid valve?
It resembles the mitral valve in structure but consists in 3 triangular membranous flaps. :)
What is a ball cock?
The valve that shuts off the water in a toilet cistern is known as the ball-cock. It is operated by a hollow ball attached to an arm, once the ball floats to a certain level, the valve shuts off the water. This action prevents water flowing out of the over-flow pipe to the outside. The ball and valve is known as the ball-cock.
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.
Top Entry Ball Valve Manufacturer in USA?
Valvesonly is a leading Top Entry Ball valve manufacturer in USA. We manufacture and supply the best quality Ball Valves to Argentina, Brazil, Morocco and Kenya. Top Entry ball valve is also known as top mounted with integral structure of its body reducing valve leakage point.In top entry ball valve internals are inserted from the top, its suitable for in line maintenance.Top entry ball valves adopt fixed both structure as all the force generated by pressure acting on the ball is absorbed by upper and lower bearing to avoid damage of the seat. Parts: • Body • Ball • Stem • Seat • Bonnet • Gasket • Bolts and Nuts • Actuator • Bearings Advantages: • Top-entry ball valves are easy to maintain because they can be repaired without removing the entire valve from the pipeline. The valve can be disassembled from the top, and the internal components can be replaced or serviced. • Cost-effective • High performance • Versatility • Reduced risk of contamination • Flexibility Industries: ● Natural Gas Industries ● Oil & Gas Industries ● Chemical Storage ● Manufacturing sector Applications: They are majorly used in pipeline industries. Valvesonly is a prominent Top Entry Ball valve manufacturer in USA which has the following features: Available specification: Material: WCB,WC6, F22, F11, F55, SS304, SS316 , DUPLEX STEEL CLASS:150 TO 2500 Know more about Top Entry Ball valve provided by Valvesonly
