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,easy operation,and fast opening and closing,making it one of the rapidly developing valve varieties in the past decade.Soft sealed ball valves evolved from plug valves,with their opening and closing components acting as a sphere that rotates 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 operations;In the power management systems of hydropower,thermal power,and nuclear power;In the water supply and drainage,heating,and gas supply systems of cities and industrial enterprises;In the irrigation and drainage system of farmland;Widely used 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 seal ball valves are used in various pipeline systems to cut off or connect medium flow,so that the medium is transported to designated points according to the predetermined program.

Features 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)Easy to operate,quick opening and closing,only need to rotate 90°from fully open to fully closed,making it convenient for remote control.
(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.When the ball rotates 90 degrees,it should appear spherical at both the inlet and outlet to intercept the flow.
