Remarks:
-
Design Standard: This valve is designed in accordance with BS5163, suitable for water supply systems and general industrial applications.
-
Pressure Rating: PN16 per BS EN 1092-2 standard. Maximum allowable working pressure is 16 bar at ambient temperature for water, oil, gas, and saturated steam (subject to temperature limits).
-
Seat Design: Bronze seat faces are achieved by overlaying (welding) or inserting bronze rings on both body and wedge, ensuring corrosion resistance and long service life.
-
Stem Design: 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.
-
Applicable Standards: This datasheet is based on BS5163 and relevant EN standards. Please confirm specific standard revisions and project special requirements before procurement.
