Remarks:

  1. Drukclassificatie: PN25 per EN 1092-2 standard. Maximum allowable working pressure is 25 barat ambient temperature for water, oil, gas, and saturated steam (subject to temperature limits).
  2. Stoelontwerp: Bronze seat faces are achieved by overlaying (welding) or inserting bronze rings on both body and wedge, ensuring corrosion resistance and long service life.
  3. Stamontwerp: Outside Screw and Yoke (OS&Y) design isolates the stem threads from the media, allowing in-line maintenance and providing visual indication of valve position.
  4. Applicable Standards: This datasheet is based on EN standards. Please confirm specific standard revisions and project special requirements before procurement.
