Stainless steel needle valve
-40 - 400 °C, max. 100 bar | MT / FT / WE
WEKA
Standard needle valves are available with nominal pressure ratings up to 100 bar, with any of three process connection types: male threaded (MT), female threaded (FT) or butt weld ended (WE). The temperature range of these standard valves is -40 °C to +400 °C. The use of valves with stem extension is recommended for low temperatures down to -196 °C (e.g., for use with liquefied gases such as N2, CO2, etc.). For temperatures above 100 °C the reduction of the allowable stress depending on the pressure-temperature rating has to be considered.
