Imported high pressure ball valve
Overview of imported high pressure ball valve products
Imported high-pressure ball valves (stainless steel high-pressure ball valves, pneumatic high-pressure ball valves, high-temperature and high-pressure ball valves, pneumatic high-pressure ball valves, fluorine-lined high-pressure ball valves) provided by YLOK International Valve Company are mainly suitable for pipelines under high pressure conditions.
Working principle of imported high pressure ball valve:
The high-pressure ball valve has the action of rotating 90 degrees, and the cock body is a sphere with a circular through hole or channel passing through its axis. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque to close tightly. The ball valve is most suitable for use as a switch and shut-off valve, but recent developments have designed the ball valve to throttle and control the flow, such as the V-shaped ball valve.
The main features of the high-pressure ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often in a closed state, which is not easy to be eroded by the medium. It is easy to operate and maintain. It is suitable for water, solvents, acids and natural gas. The working medium is also suitable for the medium with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., which are widely used in various industries. The valve body of the ball valve can be integral or combined.
Advantages of imported high pressure ball valve:
1. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.
2. Simple structure, small size and light weight.
3. Close and reliable. It has two sealing surfaces, and various plastics are widely used as the sealing surface materials of the ball valve, which has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.
4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.
5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.
8. Since the ball valve has wipeability during opening and closing, it can be used in media with suspended solid particles

Precautions for installation of imported high pressure ball valve
   a: Remove the protective caps on both sides of the flange, and rinse and clean with the valve fully opened.
   b: Before installation, the whole machine should be tested according to the specified signal (electric or pneumatic) (to prevent the vibration caused by transportation from affecting the performance), and then it can be installed online (wiring according to the electric actuator circuit diagram).
   C: Before preparing to connect with the pipeline, flush and remove the remaining impurities in the pipeline (these substances may damage the valve seat and ball).
   d: During installation, please do not use the actuator part of the valve as a lifting point to avoid damage to the actuator and accessories.
   e: This type of valve should be installed in the horizontal or vertical direction of the pipeline.
   f: The pipeline near the installation point must not sag or bear external forces. Pipe supports or supports can be used to eliminate pipeline deviation.
   g: After connecting with the pipe, please tighten the flange connection bolts crosswise with the specified torque.
