Pressure curve

График характеристик давления Yoshitake GD-26G, 27G

This graph shows the change in reduced pressure when the pressure of 0.6 MPa at the valve inlet begins to fluctuate between 0.15 MPa and 1.0 MPa, while the reduced pressure is set at 0.1 MPa.

Nominal size Pressure range Pressure offset
15-100A (A) 0.05-0.35 MPa no more than 0.05 MPa
(V) 0.3-0.7 MPa no more than 0.10 MPa
  1. Parts of the flow path are made of corrosion-resistant materials.
  2. Low noise level.
  3. The pressure balanced design of the valve allows the reduced pressure to be kept constant without being influenced by the inlet pressure.
  4. The valve top is easily removable for inspection and maintenance.
  5. Compact and lightweight, easy to install on the pipeline.

Nominal sizing diagram

Диаграмма подбора номинального размера Yoshitake GD-26G, 27G

Selection of the nominal size of the pressure reducing valve: inlet pressure (P1) - 0.3 MPa, outlet pressure (P2) - 0.2 MPa, flow rate - 200 m3 / h (standard conditions). First you need to find the intersection point (a) of the inlet pressure graph (P1) for 0.3 MPa with the outlet pressure graph (P2) for 0.2 MPa. From this point a line should be drawn down to the intersection (b) with a flow characteristic of 200 m3 / h (standard conditions). Since the point of intersection (b) lies between the sizes 25A and 32A, the larger of the two, 32A, must be selected.
* The safety factor should be taken equal to 80 - 90%.
