The OS&Y resilient-seated gate valve (DN40–DN600, GB / BS5163 / DIN F4 / AWWA) gives a clear visual open/closed indication through its rising stem, making it the standard for fire-protection mains. A fusion-bonded epoxy body and EPDM-encapsulated wedge provide long-term corrosion resistance and reliable sealing. Suitable for above-ground fire lines, plant water systems and industrial pipelines.
