Actual flow path area and flow coefficient of the safety valve

2018-07-30View Original

Thread Content

According to API526, standard flow area and letter codes: Flow channel code, Effective flow area (in2): D 0.110, E 0.196, F 0.307, G 0.503, H 0.785, J 1.287, K 1.838, L 2.853, M 3.60, N 4.34, P 6.38, Q 11.05, R 16.0, T 26.0. Choosing type K results in a flow area of 1186 mm2, with a flow coefficient of 0.975. The safety valve manufacturers explain that each company has its own specific flow channel area and flow coefficient; for some manufacturers, the flow channel area corresponding to a K value of 1 is 1352.7, with a rated flow coefficient for gases of 0.872. It doesn’t conform to the standard; is this explanation correct?
