Description

Resilient-seated gate valve with non-rising stem and brass nut type design, intended for isolation service in water, waste water, and sewage pipelines. Full bore construction permits bi-directional flow and self-cleaning of the sealing surface on each opening cycle. Hydraulic testing is performed to EN-12266-1 Class A (zero leakage); design conforms to EN-1074 with flanges to EN-1092-2 / BS4504.
