The O type shut -of ball valve is kind of quater-turn on -off vale .It is mainly used for shut-off contorl of media The ball valve of this series adopts round hole in the ball When opended It is diectly connected to the body flow channel. featured by high flow capacity.Compared With pluger valves.it has small structural sizes.light weight and the funcion of self-cleaning between plug and seat.Therefore,it is very suitable for viscous.fibrous media and those containing suspended solid particles .With low heat expansion impact due to  temperature. and good sealing performance.It is widely applied in the systems of such industries as petrochemical industry.metallurgy.chemical fiber.pulp&paper.medicine.hydroelectric station etc.to meet the needs of remote control of process parameters such as flow pressure.tempertaure and liquid level of all gases.liquids or corrosive gases and liquid media.body  main technical parmaneters

The central Ebike Motor we are referring to here is a central Ebike Motor used on lithium-ion assisted Electric Bicycles, while the common one is the Ebike Motor used on Lithium Battery mountain assisted bicycles. It was developed and put into use after the hub motor, and compared to the hub motor, the technology of the central motor is not yet very mature, so there is still a long way to go in terms of performance stability. But the central motor has a characteristic that hub motors do not have, which is its instantaneous starting assistance function, so it also has a corresponding market. The most common method is to install a center mounted motor on a mountain Electric Bike to meet the bumpy road conditions in the mountains, so both hub motors and center mounted motors have their advantages and disadvantages. The choice of motor depends entirely on which aspect of its functionality you value.Generally Speaking, the central motor is used to assist mountain bikes, and hub motors are more common on urban series of assist Electric Bicycles .
