LHD Series Solenoid Valves

3-Port Plug-In: Conventional and Lo-Lohm Models

3-Port Plug-In Style Solenoid Valve

The 3-Port HDI is a compact, lightweight solenoid valve, offering consistent performance and low power consumption. This valve is ideal for applications where a large number of valves need to be designed into the smallest area possible.

Standard part numbers for the Conventional and Lo-Lohm 3-Port Plug-In style valves are listed below. The valves are offered in a variety of different flow rate ranges, seal and other wetted materials, drive voltage configurations, operating pressure ranges and porting conditions. The Lee Company also offers customized valve performance and manifold solutions to meet specific application requirements. Select the appropriate part number for your application in the table below, or contact your local Lee Sales Engineer for technical assistance.

FEATURES:

  • Compact size: as small as 0.28" (W) x 1.12" (L)
  • Lightweight: less than 4.5 grams
  • Low internal volume: 40 µL
  • Cycle Life: 10 million cycles (silicone), 250 million cycles (FKM). Click here for additional information.
  • Leakage: 50 SµLPM max. at 5 psid air; 70°F (21°C) throughout rated cycle life
  • Flow Capacity: 450, 550, 650 and 1100 Lohm models available
  • Operating temperature range: 40°F to 120°F (4°C to 49°C)
  • Wetted materials: housing (PBT), spring (302 or 316 SS) and epoxy. See table below for seal, plunger head and armature/plunger stop wetted materials. The o-rings on all Plug-In style valves are FKM.
