Product Overview
Safety needs to be a fully integrated part in the design and production philosophy of nuclear check valves.Neway has integrated this key factor by starting and ending with 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 intermuption, seismic and end loading. This qualifies Neway to be your preferred supplier for nuclear check valves which are certified to safety class 2&3, standard class 2&3 and seismic I for nuclear industries.
Design Features
Check valves are critical equipment which contain advantages as following.To ensure sealing location repeatable, built-in disc design reduces external leakage. Bonnet joint double sealed.Disc anti-rotation structure. Especially, valve’s passageway was optimized by CFD software to minimum the flow resistance, Low pressure differential open and low pressure differential seal, Lift check valve’s online sealing performance detection function were designed and implemented in these equipments.
