TA-FUSION-P

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)

Dimensions:

DN 32-50
(DN 65-150: See TA-Modulator)

Pressure class:

PN 16

Differential pressure (ΔpV):

Max. differential pressure (ΔpVmax):
800 kPa = 8 bar
Min. differential pressure (ΔpVmin):
15 kPa = 0,15 bar
(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 [m3/h]:

DN 32: 0,88 - 4,21
DN 40: 1,01 - 6,19
DN 50: 2,71 - 11,1

qmax = m3/h at each setting and fully open valve plug.

Lift:

20 mm

Rangeability:

>100 (for all recommended settings)

Leakage rate:

Tight sealing

Characteristics:

Independent EQM.

Temperature:

Max. working temperature: 120°C
Min. working temperature: -20°C

Media:

Water or neutral fluids, water-glycol mixtures (0-57%).
