Ball Valve
High Quality 2 way 24V 220V Electric Actuator Ball Valve Motorized Ball Valve
What is electric actuator UPVC ball valve?
Electric UPVC ball valve is made of corrosion-resistant UPVC engineering materials and made of plastic ball valves. It is true union connection, with easy disassembly, simple maintenance and other characteristics. It mainly used in a variety of corrosive media pipeline for interception or regulation. Electric UPVC ball valves use electric devices to drive the valve stem and spool to operate the valve opening and closing. It very few leakage points, high strength, will not rust scaling to achieve a true sense of corrosion resistance. It is the water treatment industry and a variety of piping systems containing acid, alkali, corrosive medium products.
What is electric true union ball valve use for?
Electric UPVC ball valve is to meet the needs of a variety of corrosive pipeline fluids in a plastic ball valve and through the power supply voltage to control the valve opening and closing. in terms of work efficiency, saving time and effort, greatly improving the workload. But the electric UPVC ball valve should not be used at too high a temperature. generally according to the UPVC material temperature between -10 ℃ ~ 60 ℃ and working pressure ≤ 1.6MPA. for the pipeline containing hard particles of liquid is also not suitable for the selection of electric plastic ball valves, in order to prevent scratches on the surface of the ball or the sealing surface so as to produce leakage and so on.
How does the plastic electric ball valve work?
The electric ball valve is to drive the valve stem rotation through the motor rotating reducer to rotate the ball to the open or closed position, so as to control the flow of medium. The electric actuator can realize automatic control according to the control signal, or can be operated manually by manual device.
How to control switch of electric ball valve?
The electric ball valve switch can be controlled in the following ways:
1, Manual operation:
In general, the electric ball valve is equipped with a manual device, you can manually switch the ball valve in power failure or other circumstances.
2, Control signal:
Different control signals can be used to control the electric ball valve.
3, PLC control:
Can be programmed through the PLC to control the electric ball valve, the degree of automation is high.
4, The display control:
Some electric ball valves are equipped with a display, which can be controlled by the keys or menus on the screen.
What important effects that the characteristics of the fluid medium have on the performance and operation of PVC true union ball valves?
1, The type of fluid:
The different types of fluids have different viscosity, density and chemical properties. These differences may require different materials or design of the valve to adapt to the characteristics of the fluid.
2, Temperature:
The temperature of the fluid will affect the valve material selection and sealing performance. High-temperature fluids may require temperature-resistant materials, while low-temperature fluids may require freeze-proof design.
3, Pressure:
The pressure of the fluid can affect the wall thickness, connection and valve strength of the PVC double by order ball valve. High-pressure fluids may require robust design.
4, Corrosive:
Some fluids are corrosive, may damage the PVC material. When dealing with corrosive fluids, it may be necessary to use corrosion-resistant coatings or different materials of the ball valve.
5, Particulate matter:
If particulate matter (such as solid particles or particulate matter in suspension) is present in the fluid, these particles may abrade the seals and ball of the ball valve, resulting in leakage or valve jamming.
6.Flow rate:
The flow rate of the fluid can affect the noise level of the valve and the risk of water hammer. High speed flow may cause greater noise and water hammer, so it may be necessary to use pressure reduction measures.
7, Viscosity:
High viscosity of the fluid may require greater operating force to open or close the ball valve. The need for operating force may affect the choice of drive.
8, Bubbles and gas:
Some fluids may contain bubbles or gas, which may affect the valve's operation and sealing performance. In this case, it may be necessary to consider venting or exhaust design.
In summary, it is important to understand the characteristics of the fluid medium for the selection and performance of PVC true union ball valves. When selecting and installing valves, the appropriate valve material, design and accessories should be chosen based on the characteristics of the fluid. The valve can operate stably in a particular application and meet the process control requirements. Also, regular maintenance and inspection of the valve will help ensure its performance and longevity.
