RAYS C-type ball valve adopts a double eccentric design: the rotational center (axis) of the C-ball is offset from both the geometric center (sphere) of the C-ball sealing surface and the sealing center of the seat. This double eccentric design results in a dual-vector cam motion involving both rotation and translation of the C-ball, facilitated by the stem being offset in two planes. When the valve is closed, the C-ball and the seat interact to create a cam-action wedge tightness, achieving a torque seal. The torque required for sealing is provided by a handle, gear, or actuator, ensuring a tight shut-off that is mechanically independent of springs or process pressure
RAYS bellows sealed globe valve adopts international advanced technology and double sealing design. It has the characteristics of high-performance elastic metal bellows and extremely long expansion fatigue life. Pipe shut-off valves: improve the use of energy efficiency, increase the safety of production equipment, reduce maintenance costs & frequent maintenance, and also provide a clean & safe work environment. Bellows sealed globe valve are suitable for class 150~2500, working temperature -46°C~538°C pipeline. Using carbon steel, stainless steel and other different main materials can be suitable for various media. The optional drive devices are: hand wheel, electric, pneumatic, etc. Bellows sealed globe valves are suitable for pipelines under various working conditions in petroleum, chemical, pharmaceutical, fertilizer, electric power, and other industries.
The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
