High Pressure and High Temperature Gate Valve in Malaysia

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…

Wear-Resistant Ball Valve

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

forged steel ball valve

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…

Pig Valve dispatched by RAYS

  Recently, RAYS successfully delivered a new C-type PIG VALVE for a foreign end-user, which will be used in an important pipeline project in the Arctic, contributing to the global energy strategy.   The PIG VALVE is a new type of valve that serves as a transmitting and receiving device for pipe cleaners, and it also functions as a universal ball valve.   With the use of pig valve and the corresponding pipe cleaners, pipe cleaning, emptying, isolation and sequential…

Fully Welded Ball Valve (soft and metal seated)

Full Welding Ball Valve

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…

RAYS Supercritical Power Plant Valves – PHASE Ⅱ

Supercritical Power Plant Valves 1

The power plant valves supplied by RAYS to a supercritical power plant phase Ⅱ in Thailand have been successfully delivered. Prior to this project, the Thailand power plant owners all used European imported power plant valves for the key position of supercritical high temperature and high pressure. However, after many technical exchanges/product design ideas and quality tracking control norms, and the high quality valves supply in the last two years at the phase Ⅰ, a power plant owner has full…
