Marine Cast Steel Flanged Stop Valve (GB/T584-2008)
GB/T 584-2008
DN20-300 1.0 / 1.6 / 2.5 / 4.0 / 6.4 MPa
Isolation and throttling duties for shipboard fluid systems. Review standard, DN, pressure rating, body material and connection before inquiry.
Combined stop and non-return functions where backflow prevention is required. Confirm pressure, material and sealing requirements by model.
J-type globe valves for specifications commonly referenced in Japanese shipbuilding projects. Match standard, size, pressure and material to the drawing.
J-type stop-check valves for combined isolation and backflow prevention. Confirm connection dimensions and service conditions before quotation.
This category covers globe and stop-check series in flanged, threaded and J-type arrangements. Cast steel, cast iron, bronze and forged-steel options are grouped by standard and function, then checked against size, pressure, flow direction and certificate scope before quotation.
Before RFQ, confirm standard scope, IMPA-code data, certificate requirements, and valve-function boundaries.
Not automatically. A stop-check valve controls flow direction as well as closure, so substitution must follow the pipeline function, governing standard, installation orientation, pressure loss and certificate scope.
Send the standard or model, nominal size, pressure rating, body and trim materials, end connection, flow direction, service medium and maximum temperature, quantity, destination or delivery term, certificate requirement and target schedule.
No. Classification-society certificates, MTC, PMI, NDT and third-party inspection are applied for and confirmed by product standard and order scope.
