Lo-Lohm High Density Interface (HDI)
3-Way Solenoid Valve


    The Lee Company 's High Density Interface (HDI) solenoid valve just got better by offering more flow capacity without sacrificing size and weight. Imagine the features of a large valve coupled with the superior performance of a miniature valve in one compact design.

    A spike and hold voltage drive is used to achieve an extended flow and pressure range. Refer to the table below for spike actuation voltage requirements at 50 psid.

  • Compact Size
  • Light Weight: Less than 4.5 grams
  • Operating Pressure Range: Vac - 50 psig (0-50 psid)
  • Spike and Hold Voltage Drive Required
  • Electrical Connection: 0.025" Sq. Pin
  • Wetted Materials: PPA, PBT, 316SS, 430F SS, FKM, Epoxy
  • Operating Temperature Range: 40°F to 120°F

    General Specifications

  • Operating Pressure Range: Vac - 50 psig (0-50 psid)
  • Flow Capacity (air):
    • Plug-In, 2-Way NC (Common Inlet): 450 Lohms (39 SLPM @ 50 psid; CV = 0.044)
    • Plug-In, 2-Way NO (NO Inlet): 650 Lohms (27 SLPM @ 50 psid; CV = 0.031)
    • Face Mount, 2-Way NC (Common Inlet): 900 Lohms (19 SLPM @ 50 psid; CV = 0.022)
  • Cycle life based on testing using clean dry air is 250 000 000 cycles or more. The actual cycle life may be affected by specific application parameters.
  • Ambient Operating Temperature Range: 40°F-120°F (4°C-49°C). Increasing operating temperature range can limit the coil performance. Valve duty cycle must be evaluated for specific applications.
  • Spike and hold voltage drive required
  • Recommended Filtration: 35 microns or better
