RAYS recently delivered high pressure and high temperature gate valves and check valve for the project based in Malaysia.   The middle cavity of the valve adopts a pressure self-tightening sealing structure. The higher the inner cavity pressure, the better the sealing performance. Both ends of the branch pipe are welded structures, which are suitable for different connection requirements.   The sealing surfaces of the gate and valve seat are made of stellite cobalt-based cemented carbide, which has: good wear…

Relying on the high-tech senior engineering team of RAYS, the wear-resistant ball valve independently developed by RAYS has truly achieved zero leakage and its’ service life has reached the world’s advanced level. Advanced ball and seat hardening technology In order to ensure that the valve can adapt to: high, low temperature, and particle conditions; the ball and seat sealing surface of RAYS wear-resistant ball valve adopts advanced sealing surface hardening technology. This includes: supersonic spraying, metallurgical melting spraying, surface envoy…

Emergency Shutdown Forged Steel ball Valve   Background/work conditions of this project: The Emergency shutdown forged steel ball valve supplied by RAYS FLOW CONTROL to an offshore processing facility in Kazakhstan are ready to ship。 Before this project，the customer of this project has been using an emergency shutdown ball valve imported from Europe and the United States. After a productive discussion with the customer, we have formulated the most suitable product design plan for them. With RAYS’long-term experience in design…

Introduction of Fully Welded Ball Valve Fully welded ball valve (soft and metal seated) base on welded valve suitable for Oil & Gas production, processing, transportation, distribution, chemical and petrochemical refining on the above ground and below ground installations. The world famous design is the Cameron T31 ball valve. Technologies of Fully Welded Ball Valve Trunnion ball valves have the obturator bounded by trunnions which do not allow axial displacements of the ball itself in the flow direction; line pressure…

Introduction In this article, you will learn about the different applications of high pressure ball valve API 6D. Design pressure from 20 bar (g) to 1035 bar (g), in combination with other service conditions in hydrocarbon processes, refining, petro-chemistry, determinates ball valve construction, and material selection. The construction of the valve type includes: Cryogenic Ball Valve, LNG Ball Valve, Refining Ball Valve, Liquid Nitrogen Ball Valve, also include Control Ball Valve with Actuator motor. This application can exist in combination…
