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 [gpm]:

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 maximum 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.
Pipe threads NPT according to ANSI/ASME B1.20.1-1983. Complete thread according to ANSI B16.15-1985.
