●Description: Lift Check Valves are designed to prevent backflow
in the system in case of a power failure or a change in the flow
characteristics. In backflow conditions, the disc, guided by a stem, closes due
to a spring mechanism and achieves sealing. Drip tight sealing is achieved by
metal-metal or metal-resilient sealing mechanisms. Due to the spring driven
mechanism and short travel distance of the disc, valve closes very fast,
providing non-slam closure. In normal flow conditions, disc is opened by the
flow and Y-shaped body provides minimum pressure loss. By the help of the top
flange assembly, all parts of the valve can be dismantled easily from the valve
without removing the valve from the pipeline, causing easy maintenance.
