Max. differential pressure (ΔpVmax): 800 kPa = 8 barMin. differential pressure (ΔpVmin):DN 32-50: 15 kPa = 0,15 barDN 150: 40 kPa = 0,40 barDN 150 HF: 60 kPa = 0,60 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.
The flow (qmax) can be set within the range [m3/h]:
DN 32: 0,88 - 4,21DN 40: 1,01 - 6,19DN 50: 2,71 - 11,1DN 150: 78,1 - 207DN 150 HF: 98,7 - 261
qmax = m3/h at each setting and fully open valve plug.

Articles – Valves
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.
