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..
– Self acting valves
– Generally used at horizontal lines but they can be used in vertical lines also provided the flow direction is upwards
– The vertical and horizontal mounting is possible through the line.
– It is design to provide rapid shutdown to prevent reverse flow
– Low pressure drop and turbulence
– Long service life, when used under the right conditions
