AREAS OF USE
Macon Balancing PVM is used to distribute the flow within
different areas in heating and cooling systems.
DESCRIPTION
PVM is a dynamic valve unit developed to regulate
pressure drop. A fully open STV mounted on the
intake, and a PV differential pressure valve on the
return. The pressure-compensating mains control
valve ensures problem-free setting of the various
mains. The PVM valve is equipped with a signaling
circuit, cut-off valve, drain valve and measurement
socket as standard.
The PVM valve guarantees 100% differential pressure
regulation under all conditions, regardless of whether
changes are made in the system.
The valve regulates the system and removes noise
problems due to high pressure drop. After setting the valve
no further adjustment to the valves is necessary.
