Influence of PRV Geometry on Accuracy Rev - 1.0 / Page 17 / 10/10/2012... - Page 18 Influence of PRV Geometry on Accuracy The point of contact between the disc and the seat determines the effective seat area of the PRV. As indicated in Fig. 2, the effective area is somewhere between the inner and outer diameter of the seat. In order to accurately measure set pressure, it is extremely important that this data be accurately determined using proven engineering methods.
