Globe Valve
Explore our comprehensive range of high-performance industrial valves, engineered for reliability and precision in every application.
Product Overview
Globe valve are used to cut or connect the pipe media under nominal pressure between PN1.6 ~ 16.0MPa (Class150 ~ 2500), working temperatures ≤ 600℃ in oil industry, chemical industry, pharmaceuticals, fertilizer, and power industry.
Product Features
-
Rational structure, reliable sealing, excellent performance, pretty appearance.
-
Co-radix alloy welded sealing surface, erosion-proof, abrasion-proof and longer use life.
-
The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistant.
-
PN ≥ 25.0MPa (Class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure sealing performance.
-
There is no backward sealing structure in the valve, so the sealing is reliable.
-
The material of the filling and the flange size can be chosen and matched according to the applications and the requirements of the users. That can satisfy all kinds of working requirements.
