from DN15 to DN200 - from PN16 (class 150) to PN630 (class 2500) - from -30°C to +120°C
Description
Globe valve with outside screw and yoke. The flanged body and the bolted bonnet are made of copper alloy (#CuSn). The stem and the throttling plug are made of nickel alloy (#Monel™). The plug is designed so as to avoid fire ignition while opening the valve. The integrated seat and a very neat lapping ensure bubble-tight shut-off.
Applications
This range of valves has been specially designed for gaseous oxygen service. These valves can also be installed behind a barrier, with or without gear box. They are extensively used in industry, especially in steel plants.
