Swing Check Valves - E400

Swing check valves are produced within a wide range of sizes, which controls the flow direction. They have an obturator, which automatically blocks the flowing in one direction. Flow direction is marked on the body, for correct assembly. The vertical and horizontal mounting is possible through the line.

It is a full bore valve, suitable for the pig transition. It is used as line valve in natural gas and crude oil pipelines and also used in Pig Stations, Compressor & Metering Stations, Regulating & Metering Stations, Pumping and Filling Stations. Special sizes are available as tailor made.
