  • Page 27: Air Quality

    5.3.1 Lubrication The 4KA3、 4KB3 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.
