2 Way Ball Valves/3 Way Ball Valves Exporter introduces the difference between fixed ball valves and floating ball valves:
1. Floating ball valve
The ball of the floating ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end. The floating ball valve is small in size, light in weight, simple in structure and good in sealing performance, but the load of the ball bearing the working medium is all transferred to the outlet sealing ring, so it is necessary to consider whether the material of the sealing ring can withstand the working load of the ball medium. This structure is widely used in medium and low pressure ball valves.

Floating Ball Valve Features and Performance
Small in size, light in weight, simple in structure, the ball has free-floating function, which can better ensure sealing; the ball valve uses a ball with a circular through hole as an opening and closing part, and the ball is driven by the stem to move around the center of the stem. Rotate ~90 degrees to complete the opening and closing function; it has the characteristics of compact structure and quick switch, and can close the valve and cut off the pipeline medium by rotating 90 degrees; the diameter of the sphere channel is the same as the diameter of the pipeline, with small flow resistance and large flow capacity; the valve The rod is a bottom-mounted type, which prevents the accident of the valve rod from being pierced and ensures the safety of use;

2. Fixed ball valve
The ball of the fixed ball valve is fixed and does not move after being pressed. The fixed ball valve has a floating valve seat. After being pressurized by the medium, the valve seat moves, so that the sealing ring is tightly pressed on the ball to ensure the sealing. Bearings are usually installed on the upper and lower shafts with the ball, and the operating torque is small, which is suitable for high-pressure and large-diameter valves.

Features and performance of fixed ball valve
The fixed ball valve is suitable for various pipelines of medium and high pressure to cut off or connect the medium in the pipeline. Different materials are used, which can be respectively applied to water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid and acetic acid. , oxidizing media, urea and other media, widely used in petrochemical, electric power, water conservancy and other industries. Common driving methods for fixed ball valves are worm gear drive, manual, electric and pneumatic. Most fixed ball valves are flanged, but there are also welded versions of fixed ball valves.

Simply put: the general difference between a fixed ball valve and a floating ball valve is:

a. Floating ball valve - the valve core ball rotates freely between the two valve seat seals by means of the valve stem.

b. Fixed ball valve - the valve core ball is connected with the valve stem, and rotates around the center of the valve stem, a ball valve with a floating ball and an elastic movable sleeve valve seat.
