Adding Kv or Cv values

[Esam]

[h=Control Valves in Parallel]3[/h]

The resulting K_v or C_v if two valves are installed in parallel can be calculated as

K_vt = K_v1 + K_v2 (1)

where

K_vt = resulting K_v

K_v1 = K_v valve 1

K_v2 = K_v valve 2

[h=Control Valves in Series]3[/h]

The resulting K_v or C_v if two valves are installed in series can be calculated as

1 / (K_vt)² = 1 / (K_v1)² + 1 / (K_v2)² (2)
