1. Design features
● Two-piece valve body: The two parts of the valve body are connected by bolts or threads, which makes it easy to disassemble and maintain.
● Threaded connection: The two ends are connected by female thread (or external thread), which is suitable for small diameter pipes (such as DN15-DN50).
● Floating Ball Design: The ball is close to the valve seat under the pressure of the medium, which ensures the tightness.
● Anti-blowout valve stem design: Prevent the valve stem from accidentally disconnecting under high pressure conditions.
2. Principle of operation
● Rotate the valve stem (90°) using the handle or actuator to make the ball rotate.
● Open state: The through-hole of the ball is aligned with the pipeline, and the liquid passes through it.
● Closed state: The ball is rotated 90°, the through-hole is perpendicular to the pipeline, and the liquid is cut off.
3. Main advantages
✅ Good sealing: PTFE (polytetrafluoroethylene) or other soft sealing materials are used, which are suitable for various media.
✅ Easy to maintain: The two-piece design is removable, which is convenient for cleaning or replacing internal parts.
✅ Flexible operation: Simply rotate 90° to switch, suitable for frequent use cases.
✅ High pressure resistance: suitable for medium and high pressure conditions (e.g. PN16-PN40).
✅ A wide range of applicable media: water, oil, gas, steam and mildly corrosive liquids.
4. Areas of application
● Petrochemicals: Oil and natural gas pipeline management.
● Water treatment: water supply and drainage, heating, ventilation and air conditioning system.
● Food & Medical: Sanitary stainless steel can be used in the food and pharmaceutical industries.
● Electricity and machinery: steam and cooling water systems.
