One of the core products- stainless steel bellows globe valve, has been applied to various types of nuclear power plant system, filling the domestic blank, and our technical level has reached the leading domestic level. It can meet the external leakage requirements of nuclear power, thermal power, petroleum, chemical, pharmaceutical and other high areas. Features are as follows:
1.Simple structure, beautiful appearance, could using different connections:flange, welding, etc., easy installation and maintenance
2.Metal seal, high temperature resistance
3.Stem using the double seal structure of the packing and bellowssolve Valve leakage problem under high temperature and high pressure and corrosion and other extreme circumstances.
4.using no gasket rigidity seal structure for anti-leakage of the seals of valve flange
Operative standard
We could produce as customers’ requirements, using ASME, RCC-M,EJ,GB standard.
