Check Valves

This is a non-return type valve for preventing back flow. Upon request, the manual closing speed option can be obtained through dash-pot. It can be manufactured from special material according to NACE corrosion standards and/or temperature class.

Vastas API 6D Check Valves are used at various onshore and offshore projects, 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.
