Valves by Design Standard

API 600 Cast Steel Valves

Use this collection when the project specification calls for API 600 cast steel construction. Start with the gate valve family, then narrow the selection by pressure class, body material, end connection, trim and operation.

Buyer Selection Matrix

What Buyers Should Confirm for API 600 Valves

Pressure classClass 150, 300, 600, 900, 1500 or 2500 according to the piping class.
Body materialCommon project options include WCB, WCC, LCB, LCC, CF8M and alloy steel grades.
End connectionRF, RTJ or BW should match the line class and approved piping details.
Valve constructionConfirm wedge, stem, bonnet, seat/trim and any project-specific design requirement.
Testing & documentsState pressure test standard, MTC, PMI/NDE, coating, inspection and document package needs.

Selection Logic

Use the Standard Page First, Then the Class Page

For an early RFQ, this page helps you confirm that API 600 is the correct product family. After that, move to the API 600 cast steel gate valve page and select the required pressure class. This keeps the technical discussion tied to the actual line class instead of a generic valve description.

Project Application

Typical Project Use

API 600 cast steel gate valves are commonly reviewed for on/off isolation in refinery units, petrochemical piping, power systems and industrial pipelines. Final suitability depends on fluid, pressure, temperature, corrosion allowance, trim, operation frequency and the project valve specification.

For final selection, use the project valve specification, piping material class, approved datasheet and service conditions as the controlling documents.

Factory & Quality Evidence

Review Supplier Evidence Before PO

Buyers can review YINKE VALVE factory information, quality certificates, sample inspection records and project references before technical and commercial confirmation.

Buyer Questions

API 600 Cast Steel Valves FAQ

Does this page replace the API 600 cast steel gate valve page?

No. This is the standard-level collection page. The gate valve page contains the product range and pressure-class links used for detailed selection.

What information is most important for an API 600 RFQ?

Send valve size, pressure class, body and trim material, end connection, operation, quantity, service conditions, testing and documentation requirements.

Which end connections are commonly available?

The existing API 600 gate valve range on this site includes RF, RTJ and BW options. Final facing or weld preparation should follow the piping class and approved drawing.
