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.

Functional principle

5 / 14

Siemens Combi valves PN 25 with flanged connections CE1N4316en

Building Technologies 2018-04-18

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 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.

Engineering notes

Valve Symbols / Direction of flow Flow in control mode Valve stem

VPF53.. retracts extends

Combi valve variable closes opens

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

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

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 VPF53.. Combi valves are maintenance-free.

When performing service work on the valve or actuator:

∂Switch off the pump and disconnect power supply.

∂Close the shut-off valves in the piping network.
