4.4 Nominal size selection chart (External sensing)
* Please contact us on internal sensing method.
For example, take a pressure reducing valve whose inlet pressure (P
1
) is 0.6 MPa, reduced
pressure (P
2
) 0.4 MPa, flow rate 600 kg/h. When determining the nominal size, find the
point of intersection (A) of inlet pressure 0.6 MPa and reduced pressure 0.4 MPa. Vertically
proceed from point (A) to come across the flow rate 600 kg/h, and regard this point as (B).
Point (B) is between nominal sizes 20A and 25A. Select the larger nominal size (in this
example, nominal size 25A)
