Duplex strainerworking principle

Once installed, the valve can be inspected easily without removing it from the line and internals can be removed through the top cover. The closing mechanism can also be inspected easily without removing it from the valve by taking off the cyliner to expose the piston.

Positive Closing Check valves are designed to effectively prevent reverse flow and are ideally suited for high pressure feedwater and steam applications. The design uses a one-piece disc and relatively few moving parts to minimize operating difficulties and simplify maintenance.
