Flow coefficient Kv or Cv = Q/√ΔP, Cv = 1.168Kv 
Kv: Flow rate per hour Q (㎥/hr) at differential pressure 1 (kgf/㎠)
Cv: Flow per minute Q (Gal/min) at differential pressure 1 (PSI)
ΔP : pressure difference between both ends of the valve (kgf/cm2 or PSI)
epoxy coating
By applying NSF/ANSI Standard 61 epoxy powder coating to all valves as a basic specification, it has excellent chemical resistance to seawater, certain acids, bases, chemicals and solvents, and provides hygienic water supply to users.
Notes on product selection 
One. Check the flow performance of the product and select a diameter suitable for the required flow rate. If you select too small a bore, the supply flow will be insufficient, and if you select too large a bore, chattering may occur.
2. Our products are segmented by function. If you want additional features, please contact us.
