Electric butterfly valve belongs to a variety of electric valves and electric regulating valves.The main connection methods of electric
butterfly valve are: flange type and clamp type; the main sealing forms of electric butterfly valve are: rubber seal and metal
seal.The electric butterfly valve controls the switch of the butterfly valve through the power signal.This product can be used as a
shut-off valve, control valve and check valve for piping systems.It comes with a manual control device. In the event of a power
failure, it can be temporarily operated manually without affecting the use.
1.Under high temperature and high pressure conditions, it still has stable sealing performance.Its special sealing system can
ensure high sealing in all temperature ranges from ultra-low temperature to ultra-high temperature.
2.The three-dimensional eccentric sealing system, coupled with the optimized design, makes the valve opening resistance small.The sealing surface of the butterfly plate is a cone that has always been raised upward. When it is opened, all points on the circular surface of the butterfly plate are separated from the sealing ring at the same time, and solids are not easy to accumulate on the sealing surface.The valve closing process is completed by the elastic pressure of the sealing ring.
3.There is no phase jam between the butterfly plate and the sealing ring.
4.The sealing performance of the valve is not affected by temperature changes.
5.The valve stem shaft diameter seal adopts graphite pressing to form a sealing ring.In summary, the above ensures zero leakage, and the metal seal plus zero leakage before, during, and after the fire, so it is intrinsically fire-safe.
6.It is convenient to open and close quickly, labor-saving, low fluid resistance, and can be operated frequently.
7.The structure is simple, the size is small, and the weight is light.
8.Mud can be transported, and the liquid accumulated at the mouth of the pipeline is minimal.
9.Under low pressure, a good seal can be achieved.
10.Good adjustment performance.
The working power supply is usually: AC220V, AC380V, etc.Input signal: weak electrical signals such as 4~20mA 0~10v.After the connection between the adjustable electric actuator and the valve stem is debugged, the hard-sealed butterfly valve valve plate is driven by electrical energy as the driving force, and the 0~90° partial rotation movement is performed.Receive 4~20mA signals from the industrial automation control system to accurately control the valve opening, so as to achieve the adjustment and control of different process parameters such as flow, temperature, and pressure.
In addition, electric butterfly valves are also widely used in industrial process automatic control systems in food, environmental protection, light industry, petroleum, chemical industry, water treatment, municipal engineering, papermaking, electric power, water treatment and other industries.
Electric butterfly valves are suitable for the hvac and refrigeration industries, and can also be used in the industrial field, general service field and water treatment.
