Q11F PN16~PN63One-piece typeIntroduction to Internal Thread Ball Valve

Q11F PN16~PN63One-piece typeInternal thread ball valve is a relatively new type of ball valve, which has some unique advantages in its own structure, such as frictionless opening and closing, low sealing wear, and small opening and closing torque. This can reduce the specifications of the accompanying actuator. Equipped with a multi turn electric actuator, it can achieve adjustment and tight cutting of the medium. Widely applicable to working conditions that require strict cut-off of water supply and drainage in petrochemical cities.

Q11F PN16~PN63One-piece typeCharacteristics of Internal Thread Ball Valve

Q11FOne piece stainless steel ball valve belongs to the manual valve category. A ball valve is a valve that uses a ball with a circular channel as the opening and closing element, and the ball rotates with the valve stem to achieve the opening and closing action. The opening and closing component of a ball valve is a perforated sphere that rotates around an axis perpendicular to the channel to achieve the purpose of opening and closing the channel. Ball valves are mainly used to cut off or connect pipelines and equipment media, and can also be used for fluid regulation and control, with a wide range of applications.

1.The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.

2.Simple structure, small size, and light weight.

3.Tight and reliable, plastic is widely used as the sealing surface material for ball valves with good sealing performance, and it has also been widely used in vacuum systems.

4.Easy to operate, quick opening and closing, from fully open to fully closed, just rotate90°Easy to control from a distance.

5.Easy to maintain, ball valve structure is simple, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.

6.When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

7.Widely applicable, with diameters ranging from a few millimeters to several meters, suitable for applications from high vacuum to high pressure.
