Pressure curve

График характеристик давления Yoshitake GD-6

This graph shows the change in reduced pressure when the pressure of 0.3 MPa at the valve inlet begins to fluctuate between 0.3 MPa and 1.0 MPa, while the reduced pressure is set at 0.2 MPa.

  1. Highly accurate underpressure control even at low flow rates
  2. Simple design, less prone to failure, easy maintenance.
  3. Compact and lightweight.
