TA-Nano
Pressure independent balancing and control valve (PIBCV)
The pressure-independent balancing and control valve TA-Nano ensures optimum performance over a long life. Adjustable maximum flow enables design flow and eliminates overflows for accurate hydronic control. The TA-Nano Plus together with our balancing instruments enables advanced measuring and diagnostics.

Exact flow measuring and unique diagnostic functions for ultimate energy savings and highly reliable system.
Precise setting and ease of commissioning
Valve position visible when actuator is mounted, easy valve identification with colour coding.
High reliability
High resistance to corrosion using AMETAL®, strong resistance to dirt and completely tight valve.
Applications
Heating and cooling systems.
Functions
Control
Differential pressure control
Isolation (for use during system maintenance – see "Leakage rate")
Pre-setting (max. flow)
Dimensions
DN 10-25
Pressure class [PN]
PN 25
Differential pressure (ΔpV)
Max. differential pressure (ΔpVmax): 600 kPa = 6 bar
Min. differential pressure (ΔpVmin):
DN 10 NF/15 LF/15 NF: 15 kPa = 0.15 bar
DN 15 HF: 20 kPa = 0.20 bar
DN 20 NF: 18 kPa = 0.18 bar
DN 20 HF: 30 kPa = 0.30 bar
DN 25 NF: 25 kPa = 0.25 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.
Flow range
The flow (qmax) can be set within the range:
DN 10 NF: 18 - 180 l/h
DN 15 LF: 28 - 280 l/h
DN 15 NF: 54 - 540 l/h
DN 15 HF: 95 - 950 l/h
DN 20 NF: 120 - 1200 l/h
DN 20 HF: 160 - 1600 l/h
DN 25 NF: 220 - 2200 l/h
qmax = l/h at each setting and fully open valve plug.
LF = Low flow
NF = Normal flow
HF = High flow
