Product Description

The Yueda BS pattern gate valve is designed and manufactured in accordance with British Standards BS 5163 and BS 5150 for waterworks applications. The non-rising stem (NRS) construction keeps the overall height compact, making it ideal for underground chambers and buried installations. A fully encapsulated gate and bull-nosed wedge profile guides smoothly into the seat even in sand-laden water, while the replaceable stem nut and rolled threads guarantee easy maintenance and long life.
