Electric flange ball valve has the same 90 degree lifting action, with a circular through-hole or channel passing through its axis. The ratio between the sphere and the channel should be such that when the sphere rotates 90 degrees, it should all appear spherical at the inlet and outlet, thereby cutting off the flow.
1、 Electric actuator details Electric actuators are used to control valves and other similar products that rotate from 0 ° to 270 °, such as butterfly valves, ball valves, dampers, plug valves, louver valves, etc. They can be widely used in various industries such as petroleum, chemical, water treatment, shipbuilding, papermaking, power plants, hea1
QJ41M high-temperature ball valve/QJ641M pneumatic high-temperature ball valve/QJ941M electric high-temperature ball valve is a ball valve that uses a new sealing material as the valve seat and is sealed with similar products such as polytetrafluoroethylene. Its service life has been increased by 3-5 times. High temperature ball valves have advanta1
The PZ273H electro-hydraulic knife type gate valve controls the opening and closing of the valve through the reciprocating push position of the electro-hydraulic linkage device. If equipped with sensors or digital display devices, it can be centrally or programmatically controlled in remote and high-altitude hazardous areas. It is widely used in in1
The Q41F soft sealed ball valve not only has a simple structure and good sealing performance, but also has a small volume, light weight, low material consumption, small installation size within a certain nominal diameter range. It also has a small driving torque, simple operation, and is easy to achieve fast opening and closing. It is one of the fa1
Low temperature valves refer to valves that can be used under low temperature conditions. Valves with operating temperatures below -40 ℃ are usually referred to as low-temperature valves. Low temperature valves include low-temperature ball valves, low-temperature gate valves, low-temperature globe valves, low-temperature butterfly valves, low-tempe1
Q47H ash discharge ball valve/Q947H electric ash discharge ball valve/Q647H pneumatic ash discharge ball valve are used in the extraction, refining, processing, and pipeline transportation systems of petroleum, natural gas, coal, and ore; In the production of chemical products, pharmaceuticals, and food; In the power production systems of hydropowe1
The D971X electric clamp type soft seal butterfly valve adopts a double eccentric structure, which has a tighter sealing function as it closes, and reliable sealing performance. The sealing pair is made of stainless steel and nitrile oil resistant rubber, which have a long service life. The rubber sealing ring can be located on the valve body or on1
