The resilient-seated NRS gate valve (S4/S5, DN40–DN600, BS5163 / EN 1074-2) pairs a ductile-iron body with a fusion-bonded epoxy coating and an EPDM-encapsulated wedge to give bubble-tight, maintenance-free shutoff for clean-water duty. Its non-rising stem suits buried or space-limited installations, and the fully rubber-encapsulated gate prevents corrosion, sticking and electrolytic action. A proven choice for municipal water mains, building fire systems and potable-water networks.
