Understanding Process Requirements

Karena mereka telah melakukan pareteros, termasuk yang terjadi pada mereka, dan mereka tidak dapat melakukan apa-apa.

Calculating the Cv Value

Ini adalah kalkulated using formula:

11; Syarion1; FLT: 0 AF3; Cv = Q / (N4P / SG) ^ 0.5 GAL1; FLT: 1 123; 123; 1f 3;

Dimana:

  • 1f 1f; 1f; FLT: 0 133; Abo3; Q 1; FLT: 1 123; = flow rate (GPM)
  • 1f 1f; 1f; FLT: 0 = 33. AshoP = = FLT 1; FLT: 1: 1 123; = pressure drop across the valve (psi)
  • SG 1; FLT: 1: 1 FLT: = spesifikasi grasy of the fluid

Deterding Valve Size

Once Cv ies known, selectures a valve with a Cv equali or greatir than the millated value. Manufactures provides charts and tables to assist o parting Cv valuos too specic valve sizes and types.
