Remarks:
- Designstandard: This valve is designed in accordance with DIN3352 F4, with face-to-face dimensions per DIN 3202 F4 / EN 558 Series 14, suitable for water supply, sewage treatment, and general industrial applications .
- Bronze Seat Advantage: Bronze-to-Bronze seat trim design offers excellent corrosion resistance, wear resistance, and anti-galling properties. Compared to resilient seated valves, bronze metal seating provides higher temperature resistance and better wear resistance for demanding applications.
- OS&Y Feature: Outside Screw and Yoke (OS&Y) design allows visual indication of valve position and facilitates in-line maintenance and lubrication .
- Vorbaudesign: Stainless steel stem with rolled threads for high strength. Adjustable stuffing box ensures long-term leak-free performance .
- Coating Protection: Internal and external surfaces are epoxy coated per DIN 30677, providing excellent corrosion resistance .
- Applicable Standards: This datasheet is based on DIN3352 and relevant DIN EN standards. Please confirm specific standard revisions, pressure ratings, and project special requirements before procurement.
