Project-focused water supply gate valve with rising stem and EPDM fully wrapped wedge for zero-leakage isolation.
Product Summary
The BS5163 rising stem gate valve is designed to BS5163 standard, featuring an OS&Y (outside screw and yoke) structure with a rising stem. The valve is manufactured from QT500-7 or GGG50 ductile iron, ensuring high strength and durability. The wedge is fully wrapped with EPDM rubber, providing excellent sealing performance and corrosion resistance. Available in sizes from DN50 to DN800, with pressure ratings PN10 and PN16. This valve is suitable for municipal water supply, water treatment, and various water pipeline applications, particularly in UK, Commonwealth, and European markets.
Key Selling Points
Advanced OS&Y Design: The outside screw and yoke structure allows easy visual confirmation of valve position and smooth operation even in confined spaces.
Full Encapsulated EPDM Wedge: Provides zero-leakage shut-off and excellent resistance to corrosion and abrasion, reducing maintenance requirements.
Ductile Iron Construction: Made from QT500-7 or GGG50 ductile iron, offering high strength and impact resistance compared to grey iron.
Pressure Rating PN16: Suitable for medium-pressure water supply systems, ensuring reliable performance in demanding conditions.
Wide Size Range DN50-DN800: Meets various pipeline requirements, from residential to large municipal projects.
