Technical description
Application:
Heating (not steam) and cooling systems.
Functions:
Control
Pre-setting (max. flow)
Differential pressure control
Measuring (ΔH, T, q)
Isolation (for use during system maintenance – see also Leakage rate)
Dimensions:
3/8" – 1 1/4"
Pressure class:
230 psi
Differential pressure (ΔpV):
Max. differential pressure (ΔpVmax): 58 psi
Min. differential pressure (ΔpVmin):
Size 3/8" - 3/4": 2.2 psi
Size 1" - 1 1/4": 3.3 psi
(Valid for position 10, fully open. Other positions will require lower differential pressure, check with the software HySelect.)
ΔpVmax = The maximum allowed pressure drop over the valve to fulfill all stated performances.
ΔpVmin = The minimum recommended pressure drop over the valve, for proper differential pressure control.
Flow range:
The flow (qmax) can be set within the range:
3/8": 0.095 - 0.53 gpm
1/2" LF: 0.19 - 1.08 gpm
1/2": 0.39 - 2.07 gpm
3/4": 0.92 - 5.06 gpm
1": 1.63 - 9.46 gpm
1 1/4": 3.52 - 16.3 gpm
qmax = gpm at each setting and fully open valve plug.
LF = Low flow
Temperature:
Max. working temperature: 194°F
Min. working temperature: 14°F
Media:
Water or neutral fluids, water-glycol mixtures (0-57%).
Lift:
0.157 in
Leakage rate:
Leakage flow ≤ 0,01% of max. qmax (setting 10) and correct flow direction. (Class IV according to EN 60534-4).
