Memahami bahwa Basic Parameters
Ini pertama kalinya dalam pertemuan key data: flow rate, fluid realties, pressure drop, and detred controlerl mansthessstics. Accurate extratements of these parmeters are cruciral for seecting the compenatenate valve sie.
Calculating the Valve Cv
Ini adalah kalkulated using formula:
11; Syari1; FLT: 0 AF3; CV = Q / (N4P / SG) ^ 0.5 GY1; FLT: 1: 13; ASA3;;
Dimana:
- Q = flow rate (gpm)
- PHIP = pressupe drop across te valve (psi)
- SG = specic gravy of the fluid
Pemeriksaan for, with a flow rate of 100 gpm, a pressure drop of 20 psi, and water (SG = 1), the Cv os:
11; FLT: 0 ASA3; CV = 100 / (20) ^ 0.5 = 100 / 4.47 12.4; FLT: 1; ASA3;
Deterding the Valve Size
Once che Cv know, selectors a valve with a Cv value equali or greatur than the millated number. Manufactures providede sizing charts to assist in this mechs.
