- Options & Notes
- Stem Upgrade: Stainless Steel AISI 316
- Wedge Material: Full Stainless Steel (CF8/CF8M) or Nylon Coated Ductile Iron
- Werking: Gear Operator / Position Indicator
- Flange Facing: Flat Face (FF) or Raised Face (RF) to match counter flange
- Coating: Epoxy Coated (Blue RAL 5005 or Black), min. thickness 250μm
Remarks:
- Seat Finish: Bronze seat faces are achieved by overlaying (welding) or inserting bronze rings on body and wedge, ensuring corrosion and wear resistance.
- Stamontwerp: Rising stem design isolates stem from media, allowing easy in-line maintenance and visual indication of valve position.
- Applicable Standards: This datasheet is based on current British Standards. Please confirm specific standard revisions and project requirements before procurement.
