A floating ball valve is a quarter-turn valve that uses a ball to control the flow of fluid. They are designed with a floating ball held in place by two valve seats, one on each side of the ball. The ball moves freely within the valve body, allowing it to rotate and open or close the flow path. These valves are commonly used in various industries including oil and gas, chemical, petrochemical and water treatment. They are favored for their reliable performance, low maintenance requirements and ease of operation. Floating ball valves provide a tight seal and excellent control of fluid flow, making them suitable for high pressure and high temperature applications.

How can you choose the right ball valve from your ball valve supplier

There are many types of ball valves. It is a widely used valve that is often used to control and cut off liquid flow. It is very important to choose the correct ball valves. Let's listen to the advice of China ball valve factory - NSW

Selection of ball valve body structure:

Floating ball valve:

The ball of the 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 to ensure the sealing of the outlet. Commonly used for ball valves below 8".

Trunnion Mounted Ball valve manufacturer

Trunnion mounted ball valve:

Compared with the floating ball valve, when it is working, the force generated by the fluid pressure in front of the valve on the ball is all transmitted to the bearing, and the ball will not move toward the valve seat, so the valve seat will not bear excessive pressure. Therefore, the fixed ball valve has small torque, small seat deformation, stable sealing performance, long service life, and is suitable for high pressure and large diameter occasions.

Two piece ball valve:

It consists of a left valve body and a right valve body. Usually, cast ball valves will adopt a two-piece structure, such as WCB ball valve, CF8 ball valve, CF8M ball valve, etc. The production cost will be lower than that of forged ball valves.

Three piece ball valve:

Compared with the two-piece ball valve, it has an additional middle valve body. This structure is usually used for ball valves made of forging materials. Such as A105 ball valve, F304 ball valve, F316 ball valve, etc. The valve body of the forged ball valve will not have casting defects (such as sand holes, porosity etc.)

Side-mounted ball valve:

The inlet and outlet of the ball of the side-mounted ball valve are located on the side of the valve body, and the ball rotation axis is perpendicular to the pipeline axis

Top-mounted ball valve:

Compared with the side-mounted ball valve, the inlet and outlet of the ball of the top-mounted ball valve are located at the top and bottom of the valve body, and the ball rotation axis is parallel to the pipeline axis.

Choice of ball structure in ball valve

Full port ball valve

The valve body channel diameter of the diameter ball valve is equal to the pipeline diameter, that is, the diameter of the ball matches the inner diameter of the pipeline, usually with a lower flow resistance coefficient and a higher flow rate coefficient, which can ensure that the fluid maintains a small pressure loss and a faster flow rate when passing through the valve. In addition, due to the large sealing area between the ball and the valve seat, the sealing performance is relatively good.

ce2e2d7f2

Reduced port ball valve

The valve body channel of the reduced diameter ball valve will be reduced to a certain extent before and after the ball, that is, the ball diameter is smaller than the inner diameter of the pipe, with compact structure and light weight. However, it reduces the flow resistance coefficient and flow coefficient to a certain extent, and when it needs to handle high pressure, high temperature or corrosive media, its sealing performance may be affected to a certain extent.

V-type ball valve

The most notable feature is the use of V The V-shaped (or conical) valve seat design. This design allows the ball to form a gradually changing channel during rotation, thereby achieving precise regulation of the fluid flow. V-type ball valves are usually equipped with manual, electric or pneumatic drive devices to control the rotation angle of the ball. By adjusting the rotation angle of the ball, precise regulation of the fluid flow can be achieved (in this case, it can be called a V-type regulating valve). The V-groove design of the V-type ball valve also has a self-cleaning function. When the fluid passes through, the V-groove can guide the fluid to form a certain flushing force, help remove impurities and particles on the valve seat, and maintain the valve. Clean and unobstructed.

Choice by Multi-way Ball Valves

Full port ball valve

Two-way ball valve: It has only one inlet and one outlet. It is the most common ball valve. When there is no special indication of using a three-way/four-way ball valve, we will choose a two-way ball valve

7e4b5ce22
ce2e2d7f2

Three-way ball valve

It has one inlet and two outlets (or two inlets and one outlet). The ball is designed with a special channel inside to achieve the diversion or confluence function of the fluid.Three-way ball valves are particularly suitable for scenarios where fluids need to be distributed to two different paths or fluids from two different paths need to be merged into one path, such as cooling systems, heating systems, petrochemical pipelines, etc.

Four-way ball valve

It has two inlets and two outlets. The ball is designed with a complex channel structure inside to achieve cross-flow or diversion and confluence functions of the fluid. The four-way ball valve can flexibly adjust the distribution and mixing of fluids between multiple paths to meet complex process requirements, such as heat exchangers, distributors, mixers and other equipment.

Three-way ball valve

Pneumatic ball valve: Using compressed air as the power source, the ball is driven to rotate through a pneumatic actuator (such as a cylinder). Pneumatic ball valves are fast and responsive. Suitable for remote control or automated control systems. A handwheel operating mechanism can also be added.

Four-way ball valve:

Hydraulic ball valve: Using liquids such as hydraulic oil or water as the power source, the ball is driven to rotate through a hydraulic actuator (such as a hydraulic cylinder). The hydraulic ball valve has a large output torque and can drive large-caliber or high-pressure ball valves. Suitable for occasions with high driving torque requirements. A handwheel operating mechanism can also be added.
Electric ball valve: The on-off control of the fluid is achieved by driving the reduction mechanism or directly driving the ball to rotate through an electric motor. The electric ball valve is easy to operate and can be automatically controlled through a remote controller or a computer. Suitable for occasions where parameters such as flow, pressure and temperature need to be accurately controlled. A handwheel operating mechanism can also be added.
