US manufacturer of API valves, CORTEC, has introduced its new CX-RV2.6 Pneumatic Pressure Relief System, which is API 6A PSL 3 monogrammable and comprised of SIL 3 rated components.
The system is designed to provide rapid pressure relief within high-pressure systems, including mud pumps, managed pressure drilling manifolds and frac relief systems. Intended as a replacement to purely mechanical devices that are significantly less reliable, the CX-RV2.6 is a strong, all-pneumatic system that requires only 80 PSI minimum air supply to function.
Mike Chauvin, manager of controls and automation, CORTEC, said: “This new, simple design offers precise control and repeatability over hundreds or even thousands of pressure tripping events. We have proven this design through extensive validation over thousands of pressure cycles, with consistent tripping results within 1% or less of the pressure set point.
Users have the ability to set an auto and manual reset mode along with the reassurance that the relief valve will function efficiently when needed, protecting personnel and preserving operational safety on site.”
