1. Adopting balanced valve core structure, the axial unbalance force is small, allowing large pressure difference and good stability. The sleeve has good interchangeability, convenient assembly and disassembly, and easy maintenance.
2. The full metal valve core structure is suitable for a variety of working situations, meeting the Class IV leakage standard, and the soft seal structure valve core meets the Class VI leakage standard.
3. The valve body is designed according to the principle of fluid mechanics as a low flow resistance flow path with equal surface, the adjustable range is large, the inherent adjustable ratio is 50:1, and the rated flow coefficient is increased by 30%.
4. The actuator adopts a multi-spring structure with a height reduction of 307%. Weight reduction of 30%.
5. ZJHMW type bellows seal regulating valve forms a complete seal on the moving valve stem to block the leakage of fluid.
