Product Description

Key Features

● BS5163 type, resilient wedge design: Fully encapsulated EPDM wedge provides bubble-tight shut-off and low operating torque, making this a reliable resilient wedge gate valve for buried or above-ground service.

● Top brass stem nut for direct key operation: The gate valve with brass nut enables simple operation via T-key or extension spindle—ideal for chambers and underground installations.

● Ductile iron body & bonnet with FBE coating: Rugged construction resists impact; internal & external fusion-bonded epoxy improves corrosion resistance and hygiene in potable water valve applications.

● Flanged PN10/PN16, DN40–DN300: A compact flanged resilient seat valve footprint fits new builds and retrofits across common PN16 gate valve and PN10 systems.

● Maintenance-friendly sealing system: Multi-O-ring stem sealing and a non-rising stem layout reduce leakage risk and simplify service intervals for waterworks valves.

● Project-ready documentation: Dimensional drawings, drilling tables and pressure/temperature guidelines are available to support consultants and EPC tenders.
