American Taylor TYLER imported high temperature and high pressure welding globe valves
Product description -
American wessing TYLER imported high temperature and high pressure welding cut-off valve disc and seat sealing surface using department too vertical cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, resistance to abrasion, open/close the valve stroke is small, opening and closing time is short, lumen self-tightening seal structure is adopted, and the sealing performance is better.
Performance characteristics -
The valve stem has good corrosion and abrasion resistance after adjustment and surface nitrification.
The sealing surface of disc and seat is made of stack-cobalt hard alloy. It is durable and high temperature resistant and good abrasion resistance.
The lubricating oil is not easy to lose, the friction is small, the valve is open and easy, the movement is sensitive.
The valve disc has a short stroke, short time and good process performance.
The upper sealing structure ensures that the valve opens and runs without the stem leakage;
Application scope -
Welding of high temperature and high pressure cut-off valve is suitable for the ANSI Class150 ~ 2500 lb, working temperature - 20 ~ 570 ℃ in the petroleum, chemical, thermal power plant under various working conditions such as the pipeline, cut off or connect medium, applicable medium: water, oil, steam, etc.
Technical parameters -
Size: 3/8 ~ 4.
Nominal pressure: PN16-PN320BAR;
Working temperature: - 20 ℃ to 570 ℃;
Stem material: chromium nickel steel;
Body material: A105, F304, F316, F316L, F321, WC6, WC9;
