The Combi valves VPF53.. combine three functions:
∂ a control valve (5) for controlling the volumetric flow,
∂ an adjusting mechanism (1, 4) with a dial for a presettable maximum volumetric
flow,
∂ a differential pressure controller (3) for balancing pressure fluctuations in the
hydraulic system respectively across the control valve.
The mechanical series-connected differential pressure controller keeps the
differential pressure (p1 – p2) constant across the control valve and thus the set
volumetric flow too. The desired maximum volumetric flow can be preset with the
adjusting mechanism. The controller (not shown) and the actuator regulate the
volumetric flow and consequently the desired temperature in buildings, rooms or
zones.

p1= pressure at inlet port A of Combi valve
p2 = pressure at outlet port of control valve (5)
p3 = pressure at outlet port B of Combi valve

Medium flow
Pressure test points
The medium entering the Combi valve (inlet port A) first passes through the control
valve (5) with a linear characteristic and a stroke of 20 mm (DN 50…80)
respectively 40 mm (DN 100…150). The actuator (not shown here) opens and
accurately positions the control valve. Then, the medium flows through the variable
presetting opening (4) which is connected to the ring with dial (1) for presetting the
desired maximum volumetric flow.
Before leaving the Combi valve (outlet port B), the medium passes through a built-
in mechanical differential pressure controller (3). This differential pressure
controller is the heart of the Combi valve and ensures that the selected volumetric
flow is maintained across the whole working range and independent of the inlet
pressure p1.
The Combi valve VPF53.. is equipped with two pressure test points (P+, P-) for
measuring and monitoring the differential pressure across the valve during
commissioning. For that purpose, the electronic manometer ALE10 can be used.
Manual control
Advantages
Accessories
Manual control is only possible with mounted actuator.
The advantages of Combi valves are that:
∂ once the flow limiter is set to design flow, the hydraulic circuit self balances,
even when changes to the system are made, such as additions.
∂ for any heat demand the Combi valve with mounted actuator can be set to the
desired volumetric flow and will be relatively constant regardless of pressure
fluctuations in the system.
Constant flow regardless of pressure changes in the system reduces hydraulic
interdependence and leads to a more stable control.
