Product Overview
Safety needs to be a fully integrated part in the design and production philosophy of nuclear gate valves.Neway has integrated this key factor by starting and ending with a full awareness of safety during each step that needs to be taken during designing and production of nuclear valves. The valves are exposed to, for example a lifecycle test including 2000 cycles with high temperatures, fluid interruption, seismic and end loading. This qualifies Neway to be your preferred supplier for nuclear gate valves which are certified to safety class 2&3, standard class 2&3 and seismic I for nuclear industries.
Design Features
Gate valves are critical equipment which contain advantages as following.Wedge precisely guided during whole trip design, No-cobalt (or cobabt free) alloy hardfacing for sealing surface, Double sealed design for body-bonnet jointing, dynamic loading device for packing seals, packing on-line replace function were designed and implemented in these equipments.
