Stop Check Valve, A multi-purpose valve that functions as both a stop valve and a check valve. Its structure is similar to that of a globe valve, but the stem and disc are not fixed. When the stem is lowered and the disc is pressed tightly on the seat, it acts as a stop valve; After the stem rises, the check valve acts. On lines that require both a stop valve (or gate valve) and a check valve (such as the outlet of a water pump), using a stop check valve can save installation costs and space. In the opening and closing process, because the friction between the valve disc and the sealing surface of the valve body is smaller than that of the gate valve, it is more wear-resistant.
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 Lifting Plug Valve adopts a unique dual-action design of lifting and rotation. When opening, it first lifts and then rotates to achieve zero-friction operation. It is particularly suitable for high-pressure difference, easily crystallizing and media containing solid particles. The valve body and the plug are both precisely ground, and the self-cleaning sealing surface design ensures reliable sealing performance under harsh conditions. It is widely used in high-parameter working conditions in the petroleum, chemical and power industries.
