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 quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.

雙瓣式止回閥具有兩個半圓形，彈簧加載閥瓣安裝在中央垂直樞軸上。當閥門打開時，流體和彈簧的力作用于閥瓣的中心，使其首先從底座打開。這種設計最大限度地減少了密封在開啟過程中的磨損，提高了其耐用性。當流量減少時，由于彈簧的力量，閥瓣緩慢地向閥座移動，確保逐漸關閉。在回流過程中，閥瓣上的作用力增加，關閉速度更快，有效降低了水錘和液壓沖擊的風險。彈簧的力量首先關閉閥瓣的頂端，防止閥瓣底部的損壞，延長密封的使用壽命。
