Q941F/PPL/H electric flange ball valve


Q941F/PPL/H electric flange ball valve

1、 Overview of Electric Flange Ball Valve Products

The Q941F/PPL/H electric flange ball valve from Shanghai Yuhu Company only needs to be rotated 90 ° to fully close and open. The valve body channel and connecting pipe diameter are equal and form one diameter, allowing the medium to flow through almost without any loss. Electric flange ball valve is suitable for situations where two positions are cut off and adjusted. It is mainly divided into two categories: electric soft seal ball valves and electric hard seal ball valves. Electric soft seal ball valves are mainly suitable for media with temperatures below 250 degrees Celsius. Q941F/PPL/H electric flange ball valve is mainly suitable for media above 250 degrees. The valve has excellent sealing performance, large flow capacity, easy loading and unloading maintenance, low flow resistance, reliable sealing, and even cut-off. Electric flange ball valves have small size, light weight, high thrust, strong functionality, built-in servo amplifier, easy operation, and high reliability. The ball valve is directly connected to the actuator and has a built-in servo system, without the need for a separate servo amplifier. Input and output signals of 4-20mA and 220VAC power supply can be used to control operation. Electric flange ball valves have the advantages of simple wiring, compact structure, stable and reliable operation, etc. Electric flange ball valve is an important type of electric valve, widely used in fields such as petrochemicals and long-distance pipelines. Its closure is a partially spherical part with holes, which rotates with the valve stem to open or close the valve. Electric flange ball valves can achieve the cutting and circulation of media in transportation pipelines such as petroleum, chemical, papermaking, metallurgy, sewage treatment, and oil tank trucks.
