Material and coating
Blue epoxy 250 microns
Stainless Steel 304
3 and 14
4 and 5
Stainless Steel X20Cr13
Different operating types
Lever operated: lever made from ductile iron, blue epoxy coated (thickness 250 microns mini).
Handwheel operated: manual worm gear protected IP67 reinforced to IP68, painted basic red + blue epoxy (RAL 5005).
The headloss ∆P is expressed by the flow coefficient Kv that is the flow at a temperature of 20°C crossing the valve by triggering a headloss of 1 bar.
Those figures are tied by the simple following relation:
Kv = Q ∆P
with Q in m³/h and Kv in m³/h, ∆P in bar.
Kv values depending on the degree of the valve opening:
|DN||Degree of valve opening|
