Dimensions and technical specifikations
Material
AMETAL® is a dezincification resistant alloy.
Media:
Water or neutral fluids, water-glycol
mixtures.
Flow range
:
The flow (q
max
) can be set within the
range:
DN 15 LF: 44-245 l/h
DN 15 NF:88-470 l/h
DN 20: 210-1150 l/h
DN 25: 370-2150 l/h
DN 32: 800 - 3700 l/h
q
max
= l/h at each setting and fully open
valve plug.
Differential pressure (
D
pV):
Max. differential pressure (
D
pV
max
):
400 kPa = 4 bar
Min. differential pressure (
D
pV
min
):
DN15, DN20 = 15 kPa = 0,15 bar
DN25, DN32 = 23 kPa = 0,23 bar
(Valid for position 10, fully open. Other
positions will require lower differential
pressure.)
D
pV
max
= The maximum allowed pressure
drop over the valve, to fulfi ll all stated
performances.
D
pV
min
= The minimum recommended
pressure drop over the valve, for proper
differential pressure control.
