                                     The operating principle of motorized ball valve

The motorized ball valve has the working that revolve 90 degrees, the cock body there are circular through hole or gateway passing its shaft wires for the sphere. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. It only needs to be rotated 90 degrees and the torque can be closed tightly.

The ball valve is the most suitable to be used as a switch and a shut-off valve to develop into a design with the functions of throttle and flow controlled. Such as V ball valve, the main characteristics of the electric ball valve are compact structure, reliable seal, simple structure, convenient maintenance, closed seal surface and spherical surface, not easy to be eroded by medium, easy to operate and repair, is suitable for water, solvent, acid, natural gas and other general working medium. It also applies to medium with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valves are widely used in various industries which body can be both integral or modular. 


Summary: Stainless steel motorized ball valve

Comparing with the ordinary motorized ball valve, stainless steel motorized ball valve has good features like compact structure, small volume, light weight, close range between the seat and the end flange, less detained material and superior sealing performance. It is usually applicable to cases with strict sealing requirements and widely used in fields of Chemical, petroleum, pharmaceutical, light industry. V type channel ball structure and electronic electric actuator can be used to achieve flow regulation.V type channel ball structure and electronic electric actuator can be used to achieve flow regulation. Working pressure can reach 16MPa. Working temperature is below 550°C.

1.The principle of motorized ball valve

The motorized ball valve is mainly used in heating and air conditioning systems, and automatically opens or closes the corresponding loops or ends according to the set temperature. The piston of two-way motorized ball valve is spring reset and closure type. The motor is a synchronous motor with auxiliary control. This method is suitable for controlling a certain area before installation of the water distributor, and is also suitable for installation directly at the end, such as before the fan coil unit. The motor and valve body are connected by a live nut, which is convenient and fast to install and disassemble.


2.Composition of motorized ball valve

The often used electric actuators involve multiple rotary, single rotary, intelligent rotary, angle stroke actuators, direct stroke electric actuators, explosion-proof actuators, small actuators, etc. The ball valves mainly include floating ball valves, fixed ball valves, O ball valves, V ball valves, 3 way ball valves and so on. To configure together ball valves and actuators would produce a variety of products.

The control box can also be used as a remote operation, while adding other accessories on the actuator can also achieve more functional applications, such as adding an electrical locator to regulate the flow, the resistance / current valve position converter can be used to indicate and control the opening of the valve position, and the hand wheel mechanism can be operated manually without current. Other commonly used accessories include insulation sleeves, explosion-proof trip switches and so on. The initial selection can be selected according to the working condition.

3.Application of motorized ball valve

Motorized ball valve are now widely used in areas of oil, natural gas, medicine, medicine, food, hydro-power, nuclear power, electricity, water supply and drainage, heating, metallurgy and other industries. It is the most important mechanical product in national defense construction.It is also an indispensable product of science and technology construction which occupies a large share of the market. The main reason is that the motorized ball valve has many functions such as strong function, small size, reliable sheath, large circulation capacity, light and pleasant, remote control and so on. The motorized ball valve is not only a good product of throttling, cut-off, cutting-flow and switching-flow, but also the first choice of the most formidable product in the flow regulation system. It has many characteristics, such as pressure resistance, temperature resistance, corrosion resistance, small flow resistance, long service life, wide application range and so on.
