Technical description
Application:
Heating and cooling systems.
Functions:
Control (EQM)
Differential pressure control
Pre-setting (max. flow)
Measuring (ΔH, T, q)
Shut-off (for isolation during system maintenance)
Flushing (of the system)
Dimension:
Size 1 1/4" - 2"
(Size 2 1/2" - 6": See TA-Modulator)
Pressure class:
232 psi
Differential pressure (ΔpV):
Max. differential pressure (ΔpVmax):
116 psi
Min. differential pressure (ΔpVmin):
2.18 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.
Recommended flow range:
The flow (qmax) can be set within the range [gpm]:
1 1/4": 3.87 - 18.54
1 1/2": 4.45 - 27.3
2": 11.93 - 48.9
qmax = gpm at each setting and fully open valve plug.
Lift:
0.787 in
Rangeability:
>100 (for all recommended settings)
Leakage rate:
Tight sealing
Characteristics:
Independent EQM.
Temperature:
Max. working temperature: 248 °F
Min. working temperature: -4 °F
Media:
Water or neutral fluids, water-glycol mixtures (0-57%).
