    5.3.1 Lubrication The MN4KB2 Series solenoid valve systems use pre-lubricated valves that usually do not require lubrication from the outside. If you have to lubricate a valve, use Type 1 turbine oil (ISO-VG32) without additives. Excessive lubrication and extremely low pressure may cause a longer re- sponse time.
