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.
