Hydraulic flange ball valve is a type of ball valve with a 90 ° rotation angle. It has excellent sealing performance, high flow capacity, low flow resistance coefficient, simple structure, easy maintenance, long service life, and the valve body channel and connecting pipe diameter are equal and form a diameter. The medium can flow almost without loss. It is equipped with FDQ hydraulic actuator, small external dimensions, and high output torque. The product is usually used in occasions with strict sealing requirements. In addition to controlling gas, liquid, and steam media, it is also suitable for controlling media containing fiber impurities in water. It is widely used in various fields such as petroleum, chemical, metallurgy, light industry, papermaking, power station, refrigeration, etc.
