These innovative control and balancing valves for heating and cooling systems combine the key hydronic functions of control and balancing in one valve. Adjustable Cvmax 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.
