Cast Steel Floating Ball Valve
Cast Steel Floating Ball Valve

Cast steel ball valve opening and closing parts (ball) driven by the valve stem, and around the axis of the valve stem for rotary motion of the valve. Mainly used to cut off or connect the medium in the pipeline, can also be used for fluid regulation and control, which hard seal V type ball valve V type ball core and surfacing hard alloy metal valve seat has a strong shear force, especially suitable for containing fibers, tiny solid particles and other media.

Features And Benefits
Cast steel floating ball valve principle: floating ball valve by two pieces of seat support a floating ball. under the pressure of the medium, the ball itself will produce a certain displacement, so that the pressure to the seat sealing ring of the outlet, resulting in sealing effect. Floating ball valve according to the structure can be divided into one-piece ball valve structure, and split ball valve structure.
Standards And Norms
Ball valves are designed in strict accordance with international standards and industry codes such as ISO17292, API 608, BS 5351 and GB/T 12237. These standards ensure that ball valves meet globally recognized levels of quality, performance and safety, making them suitable for a wide range of industrial applications such as petroleum, chemical, gas and water treatment.
Construction And Sealing Performance
Ball valves feature a simple yet robust structural design with excellent sealing performance. The ball valve maintains a tight seal even under severe operating conditions of high pressure and high temperature. Low torque and easy operation enable the ball valve to maintain a smooth flow during operation, greatly reducing operating costs and difficulties.
Flow Resistance Design
Ball valves are available in both reduced and through bore configurations, each of which has been carefully designed to ensure that the fluid flows through with as little resistance as possible. In the through-bore design, flow resistance is close to zero, thus maintaining efficient fluid flow, while the reduced bore design provides higher fluid control performance to meet different operational needs.
Low Leakage Packing
To further enhance safety, this ball valve utilizes low leakage packing to prevent fluid leakage and increase valve durability. Whether under high pressure or high temperature, the low leakage packing significantly reduces the risk of leakage and ensures long-term valve performance.
Protective Design
Fire protection, anti-static and stem blowout prevention are available. The fire protection design ensures that the ball valve maintains its structural integrity at high temperatures or in the event of a fire; the anti-static design avoids sparks from static buildup, thus improving operational safety; and the anti-stem blowout feature further protects the valve’s internal components from damage and extends the life of the equipment.
Locking Function
The ball valve is equipped with a locking device that can lock it in a specific position to prevent unauthorized personnel from misuse. This feature is particularly useful in applications where a specific operating condition needs to be maintained over a long period of time, ensuring valve security and reducing potential operational risks.
Top Mounting Flange
The design of the ball valve includes a top mounting flange for easy installation in piping systems, ensuring a stable hold on the valve under all operating conditions. At the same time, the top mounting flange design provides a more convenient means of maintenance and overhaul, reducing downtime and improving overall efficiency.
