Lift Check Valve

For process lines where controlled non-return action and reliable seating are required, a lift check valve uses a guided disc or piston that rises from the seat under forward pressure and returns when flow falls or reverses. Lift Check Valve Suppliers in Morocco can provide these valves for applications where the fluid, pressure, temperature and installation conditions call for a guided check-valve design.

Applications in Morocco

Lift check valves can be applied in phosphate and fertiliser processing, chemical plants, industrial water systems, pumping stations and power-generation utilities. They are also suitable for selected steam, condensate and hot-water lines, where the guided disc arrangement provides controlled non-return action.

Standards

Depending on construction and service, applicable standards may include BS 1868, API 6D, ASME B16.34 and EN 12516. Dimensional requirements may follow ASME B16.10 for face-to-face dimensions and ASME B16.5 for applicable flanged connections, while pressure testing can follow API 598 or the specified project standard.
