Features

DongsanValve’s Cast steel valve are constructed with design of API 600, ASME B16.34 & API 6D. And It’s built up with BS 1868 additionally for Swing check valve.

Standard trim is API trim 8 for carbon steel valves, API trim 5 for chrome alloy valves, and API trim 10 for CF8M (T316) valves for optimal performance under normal conditions. Other trim materials available on request.

Seat faces lapped for smooth finish and superior sealing. Wall thickness per heavy wall API 600 requirements. Swivel disc for improved seat alignment and longer life. Each valve is shell and seat pressure tested per industry standard API 598. Check valve are suitable for service in horizontal line with cap vertical or in a vertical line with flow upward. Carrier Pin is confined within the body wall and is not accessible from the exterior, thus no side body penetrations, eliminating a common leak path, on classes 150 through 600.

End Flanges have the following raised faces per ASME B16.5: Classes 150-300: 1/16” (2mm) Classes 600-1500: 1/4” (7mm).

Each valve has a unique certification number that is traceable to the valve certification sheet which includes MTR data, pressure test, inspection result and certificate of conformance.

Other available options as follows:

-Alternate valve materials such as chrome and stainless steel alloys
-Bypass, drain and other auxiliary connections
-Gear, motor, and cylinder actuators available
-NACE service
-Special cleaning for applications such as oxygen or chlorine
-Other options available as specified
