Fixed ball valves have the following significant characteristics, which make them widely advantageous in industrial applications:

1. Sturdy structure and strong pressure bearing capacity

Spherical fixed design: The spherical body is supported and fixed by upper and lower valve stems, without displacement due to medium pressure, ensuring structural stability under high pressure conditions.

High strength materials: Valve bodies and spheres are usually made of high-strength materials such as carbon steel, stainless steel, or alloy steel, which can withstand pressures of hundreds of megapascals (MPa) and are suitable for high-pressure, large-diameter pipeline systems.

2. Excellent sealing performance

Bidirectional sealing: The sealing design of the fixed ball valve can achieve zero leakage in both directions, suitable for occasions with strict sealing requirements.

There are various sealing materials available: depending on the characteristics of the medium, metal hard seals (such as Stellite alloy) or high-performance soft seals (such as PTFE, PEEK) can be selected to ensure reliable sealing in high temperature, high pressure, or corrosive media.

Self compensation function: The floating valve seat can automatically compensate for wear under the action of medium pressure, extending the service life of the valve.

3. Small operating torque, effortless opening and closing

Low friction design: The ball and valve seat come out of contact at the moment of opening, reducing friction and lowering operating torque.

Flexible driving mode: supports multiple driving modes such as manual, electric, pneumatic, hydraulic, etc., suitable for automation control systems.

4. Wide applicability

Strong medium compatibility: capable of handling various fluids such as gases, liquids, vapors, corrosive media, etc., suitable for industries such as petroleum, chemical, natural gas, and power.

Wide temperature range: resistant to high temperatures (up to 500 ℃) and low temperatures (up to -196 ℃), meeting the requirements of extreme working conditions.

Large diameter range: can be produced from small diameters (DN15) to large diameters (DN2000 and above), suitable for different pipeline sizes.

5. Easy maintenance and long service life

Modular design: The valve body, sphere, valve seat and other components can be replaced separately, reducing maintenance costs.

Good wear resistance: The contact surface between the ball and the valve seat has undergone hardening treatment (such as spraying tungsten carbide), which has strong wear resistance and is suitable for high-frequency opening and closing occasions.

Long life design: Under reasonable operating conditions, the service life of fixed ball valves can reach several decades.

6. High security

Fireproof design: Some fixed ball valves adopt fireproof structures, which can still maintain sealing performance in case of fire.

Anti static design: Conductive springs are installed between the ball and the valve stem, as well as between the valve stem and the valve body, to prevent the accumulation of static electricity and pose a danger.

Emergency cut-off function: It can be equipped with a quick closing device to quickly cut off the flow of the medium in emergency situations.

7. Low fluid resistance

Full bore design: The spherical channel is consistent with the inner diameter of the pipeline, with low fluid resistance, suitable for situations that require high flow rates.

Streamlined design: reduces turbulence and pressure loss of the medium inside the valve, and improves system efficiency.

8. Flexible installation

Multiple connection methods: supporting flange connection, welding connection, threaded connection, etc., to meet different pipeline installation needs.

Installation at any angle: The valve can be installed horizontally or vertically without affecting its performance.

Summarize

Fixed ball valves have become the preferred valve type for high-pressure, large-diameter, and high demand operating conditions due to their sturdy structure, reliable sealing, easy operation, wide applicability, and convenient maintenance. In industries such as petroleum, chemical, and natural gas, fixed ball valves can meet the demanding working conditions and ensure the safe and stable operation of the system.
