LHD Series Solenoid Valves

Lo-Lohm Spike and Hold Reference Information

The Lo-Lohm design offers more flow capacity across an extended pressure range without sacrificing size and weight. A spike and hold voltage drive is required to achieve the extended flow performance with differential pressure ranges up to 50 psid. Please refer to the table below for porting specifications as well as spike actuation and hold voltage requirements at 50 psid. Spike voltage requirements for lower differential pressure operating ranges are shown in the graph below.
