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.

Beschreibung

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

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”.

Siemens Combi valves PN 16 with flanged connections CE1N4315en

Building Technologies 2017-10-25

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.
