Characteristics Curve (at 20 mm2/s, 50°C) (typical examples)
■ Pressure Drop CharacteristicsOverall valve pressure loss is the sum of the 4 curves of the applicable graph.
▲: Select K, M, N curve in Fig. 3 according to cracking pressure.△: One of the curves shown in Fig. 4—the K1, M1 or N1 curve—is
selected depending on the cracking pressure. (Example: K1 with cracking pressure K)
▽: One of the curves shown in Fig. 4—the K2, M2 or N2 curve—is selected depending on the cracking pressure. (Example: K2 with cracking pressure K)
