Linear Motor Proportional Valve

Parker Precision Fluidics LM-Pro Miniature Proportional Valve

 

The Parker LM-Pro miniature proportional valve provides unparalleled flow control capabilities to meet your OEM application needs. The LM-Pro uses a patented linear motor actuation technology that provides exceptional resolution over a longer stroke and lower power consumption than traditional solenoid or voice coil actuation. With a linear controllable flow up to 540 slpm, pressure capability up to 100 PSIG (6.9 Bar), and typical power consumption of less than 2 Watts, the LM-Pro is a true, one-size-fits-all proportional valve. This unrivaled performance capability combined with the simplicity of a face-mounted/ported design make the LM-Pro valve an ideal solution for your dynamic flow control needs.

Features:

  • Unparalleled Controllable Range: LM-Pro enables accurate low and high flow rate control
  • Low Power: Typical operation under 2W
  • Long Life: Tested to 100 million cycles
  • Impressive Package Size: Light weight, highest flow range in its class
  • Simple Integration: Face mount porting and optional filter reduces manifold complexity

  • Basic Control: The Parker LM-Pro valve can be controlled by either voltage or current; however, it is highly recommended that current control be employed to ensure the most repeatable valve flow performance.

  • PWM Control: For PWM control, the signal applied to the valve should have a frequency of 5 kHz or greater. Optimum frequency will be application dependent.
