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 fastest developing valve varieties in the past decade. Soft sealed ball valves are evolved from plug valves, and their opening and closing parts act as a sphere, using the sphere to rotate 90 ° around the axis of the valve stem to achieve the purpose of opening and closing. Soft sealed ball valves are mainly used in pipelines to cut off, distribute, and change the direction of medium flow, in chemical products, pharmaceuticals, and food businesses; In the power management systems of hydropower, thermal power, and nuclear power; In the water supply, drainage, heating, and gas supply systems of cities and industrial enterprises; In the drainage and irrigation system of farmland; Widely applied in the financial management system, it is an important mechanical product closely related to business construction, national defense construction, and people's lives. Manual soft sealed ball valves are used in various pipeline systems to cut off or connect the medium flow, allowing the medium to be transported to designated points according to predetermined procedures.

1Features of Soft Seal Ball Valve Products
(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) Convenient to operate, quick to open and close, with only a 90 ° rotation from full open to full close, facilitating remote control.
(5) Easy to maintain, the ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement more 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, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should be spherical at both the inlet and outlet to cut off the flow.
