Rigorous Quality Control at Every Step

From raw material sourcing to final shipment, KR enforces a multi-stage quality control protocol that ensures every valve performs to specification in the field.

01

Raw Material Inspection

All incoming materials including ductile iron GGG40/GGG50, stainless steel CF8/CF8M, and WCB carbon steel are certified and inspected against material certificates before entering production.

02

Dimensional & Appearance Check

All machined components undergo dimensional verification using calibrated measuring tools. Surface finish, thread accuracy, and bore concentricity are checked against engineering drawings.

03

Pressure & Leakage Testing

100% of valves undergo hydrostatic body and seat pressure tests per EN12266 / API598 standards. Zero leakage is our absolute requirement — no valve ships without passing this test.

04

Final Inspection & Certification

A comprehensive final inspection report is issued for every batch, covering material certifications, dimensional reports, and pressure test results — all compliant with international standards.
