Pressure independent combined balancing and control valves with independent EQM characteristics
These innovative pressure independent balancing and control valves for heating and cooling systems combine the key hydronic functions of balancing and control in one valve. Adjustable max. flow and inherent independent EQM characteristics allow correct valve sizing and optimum system controllability. The measuring points enable accurate measurement of flow, differential pressure, temperature and available differential pressure.
Key features
Adjustable max. flow
Adjustable Kvs technology allows setting to design flow.
Independent, inherent EQM characteristic
Proper EQM valve characteristic and high authority for all settings.
Self-sealing measuring points
Simple and accurate measurement for balancing, trouble shooting and power measurement.
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)
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
