Electric flange ball valve Product overview

Q941F/PPL/H Electric Flange Ball Valve can be completely closed and opened only by rotating 90℃。The body valve passage and the link diameter are equal and one diameter,the medium can flow almost without loss. Electric Flange Ball Valve is suitable for two position cutting、regulating occasion. Mainly divided into two categories: Electric soft sealing ball valves and electric hard sealing ball valves , Q941F/PPL/H Electric soft sealing ball valve is mainly suitable for medium with temperature below 250 ℃.The valve has excellent sealing performance, large circulation capacity, convenient handling and maintenance, low flow resistance, reliable sealing and even cut off. Electric flange ball valve is small in volume, light in weight, large in thrust, strong in function, installed in servo amplifier, convenient in operation and high in reliability. Ball valve and actuator adopt direct connection mode, built-in servo system, no need for additional servo amplifier, Input and output signal 4-20mA and 220 VAC power supply can control the operation. Electric flange ball valve has the advantages of simple connection, compact structure, stable and reliable operation and so on. Electric flange ball valve is an important kind of electric valve, which is widely used in petrochemical industry and long distance pipeline. The closing piece is a partial sphere with holes, which rotates with the stem to open or close the valve. Electric flange ball valve can cut off and circulate the medium in transportation pipeline such as petroleum, chemical industry, papermaking, metallurgy, sewage treatment, oil tank truck, etc.
