Naishi welded filtering ball valve integrates shut-off and filtration in one compact unit, ideal for fluid pipelines requiring space-saving and easy maintenance. Compared to traditional setups that separately install valves and filters, this self-filtering valve simplifies installation, improves flow cleanliness, and reduces cost.
When open, the valve filters media via its built-in mesh. When closed (rotated 90°), it serves as a reliable shut-off. Drain and middle flanges allow quick manual or automatic cleaning.
All-welded body: zero external leakage
Integrated filter and ball design: one valve, multiple functions
Compact and lightweight: saves space and installation costs
Filter mesh with sloped inlet: blocks particles >4.5mm while maintaining flow
C-PTFE seal (20% carbon): zero leakage under rated pressure and temperature
Built-in pressure relief design: safer operation
Optional motorized/pneumatic flushing
Easy maintenance via flange access
