NAMUR

The used of turbine oil at temperatures lower than 0C leads to increased viscosity and may cause the valve to malfunction. d n i n i W g c e t i r o i d n e p a t e p i P Leakage Voltage It must be noted that when connecting C-R element parallel to switching element, leakage current flows through C-R element and the leak voltage increases. 2 thread to be left exposed Clamping Torque Switching
