Electric Butterfly Valve belongs to a variety of Electric Valve and Electric Actuator. The Butterfly Valve Electrical is flange and clip; the electric butterfly valve is rubber seal and metal seal. The electric butterfly valve controls the switch of the PVC Butterfly Valve through the power supply signal. The product can be used as a piping system cut-off valve, Control Valves and Plastic Check Valve. Equipped with manual control device, in case of power failure, can be temporarily used with manual operation, do not affect the use.
With the development of electric valves, there are many well-known valve enterprises at home and abroad to produce electric valves, electric butterfly valve is an important execution unit in the field of industrial automation control. It belongs to a variety of electric valves and electric control valves. Widely used in textile, power station, petrochemical, heating and refrigeration, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection and other fields. The product can be used as a piping system cut-off valve, Electric Control Valve and check valve. Complete manual control device, electric or pneumatic transmission device, can meet the different specific conditions. Meet the most stringent quality requirements and enable very durable applications. Especially in the metallurgical steel, shipbuilding industry, has a very high visibility.
Classification: There are two common electric butterfly valve: clip electric butterfly valve and flange electric butterfly valve. The clip electric butterfly valve is a double-head bolt to connect the valve between the two pipe flanges, the flange electric butterfly valve is the valve with a flange, with bolts to connect the valve on the two ends of the flange to the pipe flange.
Advantages: 1, the electric butterfly valve opening and closing is convenient and fast, labor-saving, small fluid resistance, can be often operated. 2. The electric butterfly valve is simple in structure, small in size and light in weight. 3. The electric butterfly valve can transport mud and accumulate the least liquid at the pipe port. 4. Electric butterfly valve can achieve good sealing under low pressure. 5. Good adjustment performance of the electric butterfly valve.
Disadvantages: 1, the use of the pressure and working temperature range is small.2. Poor sealing performance.
Installation and maintenance: 1. During installation, the valve valve should be stopped in the closed position. 2. The opening position should be determined according to the rotation Angle of the butterfly plate. 3. The butterfly valve with a bypass valve should first open the bypass valve before opening. 4. It should be installed according to the installation instructions of the manufacturer. The butterfly valve with large weight should be set up with a solid foundation.
