6. Options & Notes
-
Stem Upgrade: Stainless Steel AISI 316
-
Wedge Material: Full Stainless Steel (CF8/CF8M) or Nylon Coated Ductile Iron
-
Operation: 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.
-
Stem Design: 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.
