Piston Valve Flow Measurement & Control

Piston valve flow measurement utilises a piston resting in the valve seat of a housing that moves vertically in the direction of thr flowing medium, the travel of the piston being proportional to the flow rate.

Piston Valve Flow Switch

The GHM Honsberg VD-GR flow switch uses flow volume to raise a piston from a valve seat against a spring force.
The piston actuates a hermetically separated reed switch via a magnetic coupling.
  • Sizes from G1/4 to G3
  • PN16..25
  • 1..600 l/m water
  • Highly reproducible
  • Precise, stepless adjustment of the switching value
  • Insensitive to dirt
  • Short installation length
