Nuclear certification with ASME N-stamp

Anchor/Darling manufactures gate, globe and check valves with ASME Nuclear Component (N-type) certification. Providing tight shutoff under the most severe conditions, Anchor/Darling valve designs resist the effects of extreme temperatures, gross thermal transients, high and low differential pressures, and dual-phase fluids.


For applications that include local leak rate testing (LLRT), Anchor/Darling check valves can be supplied with resilient seating materials such as ethylene propylene rubber (EPR), ethylene propylene diene monomer (EPDM) or a metallic seat with controlled bandwidth.
