  1. LHQ Series Quiet Operation Solenoid Valve

    LHQ Series Quiet Operation Solenoid Valve
    The Lee Company's new LHQ Series Quiet Operation HDI is a miniature 3-port solenoid valve designed to achieve patient comfort by reducing actuation noise by 50%. A typical solenoid valve has an inherent clicking sound when energized, which is caused by the metal-to-metal contact of the moving armature and stationary core. This new quiet operation design uses whisper technology to provide a sound level measurement of less than 37 dBA when measured at a distance of 12 inches and a valve cycle frequency of 10 Hz.
  2. Lohm Calculator App

    Lohm Calculator App
    The Lee Company is a leading supplier of miniature, precision fluid control products to a wide range of industries. Our product range includes Lohm Calculator App.
  3. Lohm Definition

    Lohm Definition
    A Simplified System of Defining Fluid Resistance Over the years, The Lee Company has developed the Lohm system for defining and measuring resistance to fluid flow. Just as the "ohm" defines electrical resistance, the "Lohm" or "liquid ohm" can be used as a measure of fluid resistance. The Lohm is defined such that 1 Lohm will flow 100 gallons per minute of water with a pressure drop of 25 psi at a temperature of 80°F. Since resistance is inversely proportional to flow, by definition: By using Lohms, one can specify performance without concern for coefficients for discharge, passageway geometrics, physical dimensions or tolerances. The resistance of any flow can be expressed in Lohms and confirmed by actual flow tests. Lohm Laws generalize the Lohm definition and allow the system designer to specify Lohm requirements for particular application based on the desired pressures and flow rates. See below for a graph relating Lohms to hole diameter and flow coefficient, Cv.
  4. Lo-Lohm High Density Interface (HDI) Solenoid Valve

    Lo-Lohm High Density Interface (HDI) Solenoid Valve
    The Lee Company is a leading supplier of miniature, precision fluid control products to a wide range of industries. Our product range includes Lo-Lohm High Density Interface (HDI) Solenoid Valve.
  5. Lo-Lohm Latching 3-Port HDI Solenoid Valve

    Lo-Lohm Latching 3-Port HDI Solenoid Valve
    The Lee Company continues to expand its High Density Interface (HDI) solenoid valve platform by combining the high flow capabilities of the Lo-Lohm design with the power savings of our Latching design, all within a compact footprint. After supplying only a momentary (10 ms minimum) voltage pulse, this magnetically-latched solenoid valve will hold its flow state until a follow-on momentary voltage pulse (with reverse polarity) is applied to switch its flow direction. Aside from the momentary pulse, no power is consumed while maintaining each flow state.
