LHD Series Solenoid Valves

Spike and Hold Driver Accessory

Spike Hold Driver Accessory

As a new accessory to the Lo-Lohm LHD Series High Density Interface (HDI) solenoid valves, the Spike and Hold Driver provides added value by allowing quick and easy prototype setup. The driver requires only a single input voltage to operate; everything else is pre-programmed and no user adjustments are required. Each driver is also equipped with an LED indicator.

  • Compact size
  • Simplifies the testing process
  • Single voltage source
  • LED indicator for operational feedback
    • Steady LED indicates correct installation and sufficient supply current to the driver.
    • Flashing LED indicates improper installation or insufficient current supply.

The Spike and Hold Drivers were tailored for use with specific 2-Port and 3-Port Lo-Lohm LHD Series valve part numbers. Select the appropriate driver part number from the table below to match your Lo-Lohm LHD Series solenoid valve part number. The drivers are polarity specific, which means the required input voltage must be applied to the positive (+) terminal. Refer to the table below for additional information and contact your local Lee Company Sales Engineer for technical assistance.

Spike Hold Driver Accessory Line Drawing

The Spike and Hold Driver Accessory uses a current-driven PWM electrical drive to achieve the required spike and hold power levels. The required control signal (input voltage) and effective solenoid operating current (output) are shown in the signal graphs above. Refer to the individual Spike and Hold Accessory inspection drawings and the LFIX1002300B reference drawing for details. To ensure proper operation, reference parameters “A” through “E” as shown in the table, below.

(1) The Lo-Lohm HDI solenoid valves are available with either a silicone (1) or FKM (2) internal elastomer seal. Refer to the individual valve drawings for a complete list of wetted materials.
(2) Due to integrated circuit requirements, the required input voltage to the driver is higher than the rated spike voltage of the valve. Refer to the individual valve drawings for specific performance requirements.
(3) The maximum cycling frequency and duty limits only apply when using the referenced LEDX driver part numbers together with the solenoid valve. Refer to the individual valve drawings for specific performance requirements related to using the valve without the referenced LEDX driver part numbers.
