Kofloc Model 3000 Small Proportional Solenoid Valve

Kofloc Model 3000 Small Proportional Solenoid Valve maintains flow control characteristics with a hysteresis of 15% or less (full-scale current). This ultra-compact proportional solenoid valve is perfect for automatic gas flow control of gas chromatographs and various other analyzers. With its high resolution, the Model 3000 is also suitable for precision pressure control.

KOFLOC strives for thorough quality control at domestic factories.
In recent years, we have also been focusing on product development for liquid measurement and control equipment, and we will deliver products that can be trusted as “Fluid Kofloc” to the world.

Features

  • Ultra-compact, lightweight, and high-performance proportional valve for a single power source
    Low power consumption (max. 2 W)
  • The annealed magnetic materials and specially designed flat springs completely prevent current fluctuations caused by vibrations due to plunger runout or friction.
  • The magnetic yoke is shaped by cutting, not bending, and annealed to eliminate interference in the magnetic flux passage and increase magnetic force.
  • Hysteresis not exceeding 15%, the lowest in the industry
  • Compliance with RoHS
