The program controlled globe valve is the most common vale for PSA devices. The kind of valves are widely used in both domestic and foreign PSA units owing to its simple and reliable structure, tight seal with no wearing, short acting duration and long service life of sealing. This high-performance program controlled globe valve designed and developed by CTYC has today developed into its 5th generation. This type of valve is continuously being developed and consummated during its application and has reached very high level whether in structure, material or completeness of valve. In recent years, it has been used in many large-scale units in the fields for petrochemical, chemical, steel, etc. As well as
The replacement of the similar imported products.
