WDL Valve Monel valves are specified for selected seawater, marine, chemical and hydrofluoric-acid services where resistance to particular reducing environments and chloride stress-corrosion cracking is required. Available designs include ball, butterfly, gate, globe, check, plug and special-purpose valves using Monel 400 or project-specified nickel-copper alloys.

Material guidance: Monel 400 offers useful resistance in many flowing seawater and reducing-media applications, but it is not universally suitable. Aeration, stagnant seawater, galvanic coupling, oxidizing contaminants, acid concentration, temperature and velocity can materially change corrosion behavior. The body, trim, fasteners, seats, packing and welding consumables must therefore be reviewed as one pressure-containing assembly.

Standards and RFQ data: Products can be supplied to applicable ASTM, ASME, API, ISO, NACE and marine project requirements. Send valve type, size, pressure rating, exact medium composition, concentration, impurities, temperature, pressure, flow condition, connection, seat, actuator, inspection, PMI, NDE and material-certificate requirements.
