What pressure classes are available?
Class 150, 300, 600, 900, 1500, and 2500 in sizes 1/2" (15 mm) to 24" (600 mm) and above on request.
Is API 600 certification available?
Our WCB gate valves are designed and tested per API 600 with API 598 hydrostatic test reports and EN 10204 3.1 material certificates.
