Remarks:

Bronze Seat Advantage: Bronze-to-Bronze seat trim design offers excellent corrosion resistance, wear resistance, and anti-galling properties, making it ideal for clean water, seawater, and various industrial media.
Padrão de design: This valve is designed in accordance with DIN3352 F4, suitable for water supply systems and general industrial applications.
Non-Rising Stem Feature: NRS design means the stem does not rise with the wedge; it only rotates. The overall height remains constant regardless of valve position, making it ideal for limited installation spaces or direct burial applications.
Classificação de pressão: PN16 per DIN EN 1092-2 standard. Maximum allowable working pressure is 16 bar at ambient temperature.
Large Size Consideration: DN800 valve is heavy and requires significant operating torque. Gearbox operation is mandatory. Please confirm installation space and lifting arrangement.
Seat Finish: Bronze seat faces are achieved by overlaying (welding) or inserting bronze rings on both body and wedge, ensuring long-term reliable sealing performance.
Applicable Standards: This datasheet is based on DIN3352 and relevant DIN EN standards. Please confirm specific standard revisions and project special requirements before procurement.
