JIS Standard Cast Steel Ship Ball Valve for Industrial Fluid Control
Introduction:
Our JIS standard cast steel ship ball valve is a premium industrial valve designed primarily for cutting off or connecting media flow in pipelines. Additionally, it serves as an efficient tool for fluid regulation and control. This versatile valve finds extensive applications across a wide range of industries, including petroleum, chemical processing, metallurgy, electric power generation, construction, heating systems, water supply and drainage, and water treatment facilities.
Features:
- Connection Types: The JIS standard ship ball valve is available in both flange type and threaded connection type, catering to different pipeline requirements while maintaining the same overall design structure and opening/closing mechanism. The valve features a spherical opening/closing part that rotates 90° around its central axis to control media flow.
- Compact and Lightweight: Medium and small diameter ball valves boast a simple structure, compact size, and lightweight design, making them easy to install and handle.
- Low Fluid Resistance: Among all valve types, ball valves offer the lowest fluid resistance due to equal cross-sectional areas of the valve body passage, ball passage, and connecting pipe when fully open, allowing for straight-line communication.
- Quick and Easy Operation: The valve opens and closes quickly and conveniently, without restricting the flow direction of the medium.
- Low Opening/Closing Torque: Compared to plug valves, ball valves require less torque to open and close due to their smaller sealing surface contact area, reducing labor intensity.
- Excellent Sealing Performance: The sealing ring material, primarily plastic, provides a low friction factor, ensuring good sealing performance. When fully open, the sealing surface is not eroded by the medium, extending the valve’s service life.
