API 600 Trim Number Chart & Service Coverage
Dalmine Flanges is a well-known Check Valve, Gate Valve & Globe Valve Manufacturer and Supplier in India. The API600 trim chart specifications are primarily designed for API600 Gate valves. The same trim numbers are more loosely applied for API603 gate valves as well as globe and check valves. In large parts of the world globe valves and check valves are ordered as BS1873 & BS1868 not API (BS spec is now converted to ISO specification). Check valves are also manufactured to API6D specifications. Once again, for globe and check valves traditionally the BS specification (now ISO specification) has been adopted by many manufacturers.
