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.

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 different types of shower valve stems available in the market?
The different types of shower valve stems available in the market include compression, ball, cartridge, and ceramic disk valves.
What is the advantage of using hybrid ceramic ball bearings?
The advantage of using hybrid ceramic ball bearings is that they will have the capabilities of both ceramic and steel which makes the ball bearings flexible yet durable.
Difference in Alumina ball and ceramic ball?
Alumina ball is a kind of ceramic balls. Here are at least four kinds ceramic balls as I know--Silicon Nitride balls, Silicon Carbide balls, Zirconia balls and Alumina balls.
How is working motorized operated valve?
motor is used as a actuator here. we can use globe,ball,butterfly type valves
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.
What does wsp valve mean?
W = Working S = STEAM P = PressureUsually followed by 150 WSP -WOGW= Water O = oil = G = GasThis is how you know a valve is RATED
What are ceramic ball bearings used for?
Ceramic ball bearings are used for reducing frictional rotation, and to support radial and axial loads. It helps any application looking to have higher RPM.
What are the advantages of ceramic gate valve?
The first feature is the double congestion and emission function：the fixed ball used spring floating seat, no matter open or closed. The fluid is stopped by valve seat beside the upstream and downstream and the residue left in the cavity is let out through drain valve. s automatic pressure relief function: when the rising medium temperature in valve cavity arouses unusual boost, there is no need to use safety valve to let out pressure automatically but just depends on the valve seat function, which is very important to the safety of liquid medium transportation. The third feature is the fire proofing structure: valve has the function of fireproofing and both its design and manufacture follow theAPI607 and API6FA code requirements.
A ball valve is used for what?
A ball valve is used to turn water , gas or oil on and off.
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.
