*1. The product adopts the external impulse tube method due to better process control. An internal impulse tube option is available, however the Cv value is different.

* 2. If the set pressure is between 0.02 and 0.1 MPa, there must be no back pressure.

(Example)
When selecting the nominal size of the primary pressure control valve at inlet pressure (P1), outlet pressure (P2) and flow rates of 0.6 MPa, 0.4 MPa and 600 kg / h, respectively, first find the intersection point (a) of the pressure lines inlet 0.6 MPa and outlet pressure 0.4 MPa. From this point, draw a line down to the intersection with the 600 kg / h line - the point of intersection (b). Since the intersection point (b) is between the 20A and 25A dimensions, select the larger of the two, 25A.
