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.

The quality issues raised by customers should be responded to quickly, the quality issues that arise should be solved in a timely manner, and products and services should be actively improved to continuously improve customer satisfaction.
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 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:
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
The three piece ball valve is usually composed of a valve body, a ball and a valve stem. The valve body is divided into three pieces, and the ball rotates in the valve body to achieve the switch function.
The three-piece ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium.
Side entry ball valve
The inlet and outlet of the ball of the side entry ball valve are located on the side of the valve body, and the ball rotation axis is perpendicular to the pipeline axis
Top entry ball valve
The ball of the top entry ball valve is located on the upper part of the valve. This design allows the internal components to be replaced and maintained without disassembling the pipeline, greatly reducing maintenance time and cost.
Modular design: Key components such as the ball, valve seat and seal can be quickly disassembled and replaced.
Low operating torque: The contact area between the ball and the valve seat is small, and the operating torque is low.
Self-cleaning characteristics: The rotation of the ball can scrape off the scale on the valve seat and reduce the obstruction of fluid flow.
Multiple sealing materials: Seals of different materials can be selected according to different media characteristics.
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.
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
Straight through ball valve
A straight-through ball valve is a ball valve without any obstruction inside the valve body. It is usually in the shape of a long strip connected by two flanges. Straight-through ball valves are mainly used in situations where the medium flow is large. Because the direct diameter is the same, the medium can flow smoothly regardless of whether the switch state is open or closed.
Three way ball valve
The three way ball valve is a ball valve used for diverting, converging and changing the flow direction of the medium. According to its different structures, the three way ball valve is mainly divided into T type ball valve and L type ball valve. The T type three way ball valve can connect three orthogonal pipelines and cut off the third channel, which is suitable for diverting and converging operations; while the L type three way ball valve can only connect two orthogonal pipelines, and is mainly used for distribution.
Four way ball valve
The 4 way ball valves 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.
Choice of ball valve actuator operation
Manual ball valve
The ball is driven to rotate by rotating the handle or turbine to control the on and off of the fluid. No external energy is required, and the reliability is high. Suitable for small pipeline systems or occasions that require frequent manual operation.
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.
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
It controls the opening and closing of the ball valve through the electric actuator, thereby achieving control of the medium in the pipeline. The electric ball valve consists of an electric actuator and a ball valve body. By inputting a standard signal, the motor group drives the worm gear angular torque to adjust the valve with a switch box.
Choice ball valve by valve material
Carbon steel ball valve
Carbon steel ball valve is a kind of ball valve made of carbon steel material, which is a kind of fluid control equipment. It controls the on and off of the fluid by the rotation of the ball.
It is divided into cast steel ball valve and forged carbon steel ball valve. It can also be divided into low carbon steel carbon ball valve, medium carbon steel ball valve, high carbon steel ball valve, etc.
