The Combi valves VPF43.. 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.

Functional principle

5 / 14
Siemens Combi valves PN 16 with flanged connections CE1N4315en
Building Technologies 2017-10-25
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 VPF43.. 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 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.

ALE10
ALE10
Electronic manometer excluding measuring lines and measuring tips.
Measuring range 0 .. 700 kPa. A differential pressure of more then
1000 kPa will destroy the pressure sensor.
For measuring the differential pressure between P+ and P- of the
Combi valves (refer to diagram under "Functional principle" on page 4).
Functions of the manometer:
Start/stop
Automatic zero position
Backlit display
Display: Out outside the measuring range
Holding function

Hint: You can also determine the volumetric flow using the valve slide rule.
4. Select Combi valve VPF43..
Ideally, Combi valves should be selected such that they operate at about 80%
of their maximum flow, enabling them to deliver spare capacity, if required.
Selection: VPF43.65F24 ∆pmin = 35 kPa
VPF43.65F35 ∆pmin = 70 kPa

The direction of flow indicated (arrow on the valve body) is mandatory!
The valves should preferably be mounted in the return pipe where temperatures
are lower and where the sealing gland is less affected by strain.
Symbol used in catalogs and application descriptions
Symbol used in diagrams
There are no standard symbols
for Combi valves in diagrams.
A strainer or dirt trap should be fitted upstream of the valve to enhance reliability
and service life.
Remove dirt, welding beads etc. from valves and pipes.
Do not insulate the actuator bracket, as air circulation must be ensured!
Mounting notes
Combi valve and actuator can be easily assembled on site. Neither special tools
nor adjustments, besides the presetting, are required. Prior to mounting the
actuator, the required volumetric flow must be set. The valve is supplied with
Mounting Instructions (74 319 0711 0).

Installation notes
It is recommended to mount the actuator before the presetting is made.
1. Mount actuator and fix valve neck coupling
2. Mount valve stem coupling and tighten slightly
3. Make presetting according to table under "Volumetric flow/dial presetting" on
page 6. Do NOT adjust presetting to a dial reading lower than “0.6”.
4. Tighten stem coupling
8 mm
Using an open-end
wrench and turn the
stem with dial to the
desired presetting
position.

Commissioning notes
The valves must be commissioned with the actuator correctly fitted. Strong
pressure impacts can damage closed Combi valves.
The Combi valves have to be open when flushing or pressure testing the
system. Strong pressure impacts can damage closed Combi valves.
Differential pressure Δpmax across the valve’s control path is not allowed to
exceed 600 kPa.
Only possible with mounted actuator.
Maintenance notes
The VPF43.. Combi valves are maintenance-free.
When performing service work on thevalve or actuator:
Switch off the pump and disconnect power supply.
Close the shut-off valves in the piping network.
Fully reduce pressure in the piping network and allow the pipes to cool down
completely.
Remove the electrical connections only if necessary.
The stem sealing gland cannot be exchanged. In case of leakage the whole valve
must be replaced.
Do not dispose of the device as household waste.
Special handling of individual components may be mandated by law or
make ecological sense.
Observe all local and currently applicable laws and regulations.
Warranty
Application-related technical data are guaranteed only when the valves are used in
connection with the Siemens actuators listed under "Equipment combinations" on
page 3.
Siemens warranty is void, if used with non-Siemens actuators.
