Safety Notes

Prior to assembly and commissioning

to avoid injury of persons and damages

of the devices, it is absolutely necessary

to carefully read and observe these

instructions.

Necessary assembly, start-up, and

maintenance work must be performed

only by qualied, trained and authorized

personnel.

Prior to assembly and maintenance work

on the controller, the system must be:

- depressurized,

- cooled down,

- emptied and

- cleaned.

Please comply with the instructions of the

system manufacturer or system operator.

Denition of Application

The controller is in combination with

electrical actuators (AMV(E) 1_,2_, 3_, 150)

used for:

- ow and temperature control (AHQM) or

- di. pressure and temperature control

with ow limitation (AHPBM-F)

in water and water glycol mixtures for

heating, district heating and cooling

systems.

The technical parameters on the product

labels determine the use.

Assembly

Admissible Temperatures

Admissible Installation Positions

The controllers can be installed in

horizontal or vertical pipes with

(connection neck for) electrical

actuator oriented upwards.

Electrical actuator

Installation positions for electrical

actuator AMV(E) have to be observed as

well. Please see relevant Instructions.

Installation Location and

Installation Scheme

AHQM return mounting

AHQM ow mounting

AHPBM-F ow mounting

AHPBM-F controller can only be installed in

ow pipeline in direct-connected heating

system with mixing loop.

Valve Installation

1. Clean pipeline system prior to assembly.

2. The installation of a strainer

 in

front of the controller is strongly

recommended.

3. Install valve

• The ow direction indicated on the

product label or on the valve  must

be observed.

• The valve with mounted weld-on

tailpieces may only be spot welded to

the pipeline .

The weld-on tailpieces may be welded

only without the valve and seals! 

If these instructions are not observed,

high welding temperatures may

destroy the seals.

• Flanges

 in the pipeline must be in

parallel position and sealing surfaces

must be clean and without any

damage.

Tighten screws in anges crosswise

in 3 steps up to the maximum torque

(50 Nm).

4. Caution:

Mechanical loads of the valve body by the

pipelines are not permitted.

Mounting of electrical actuator

Place electrical actuator AMV(E) on the

valve and tighten union nut with wrench

SW 32.

Torque 25 Nm.

Other details:

See instructions for electrical actuator

AMV(E).

Impulse tube mounting

• Which impulse tubes to use?

Use impulse tube set AH



• Connection of impulse tube  in the

system

• Connection to the pipeline

It is strongly recommended to install

the impulse tube to the pipeline

horizontally  or upwards .

This prevents dirt accumulation in the

impulse tube and possible malfunction

of the controller.

Connection downwards is not

recommended

.

Insulation

The controller  may also be insulated.

Insulation of electrical actuator 

AMV(E) is not allowed.

Dimensions, Weights

(See page 2)

Conical ext. thread acc. to EN 10226-1

Flanges PN 25, acc. to EN 1092-2

Start-up

Filling the system, rst start-up

1. Slowly open shut-o valves that are

possibly available on the impulse tube

(AHPBM-F).

2. Open valves in the system.

3. Slowly open shut-o devices

 in the

ow pipeline.

4. Slowly open shut-o devices

 in the

return pipeline.

Leak and Pressure Tests

Pressure tests should be carried out prior

to the installation of the electrical actuator.

This guarantees that the valve is opened.

Before pressure test, open the adjustable

ow restrictor  by turning it to the left 

(counter clockwise).

Adjustable ow restrictor  has to be

moved by hand not by tool.

Pressure must be gradually increased at

the (+/-) connection .

Non-compliance may cause damages at

the actuator or the valve.

A pressure test of the entire system

must be carried out in accordance with

manufacturer’s instructions.

The maximum test pressure is: 1.5 × PN

PN - see product label!

Putting out of operation

1. Slowly close shut-o devices  in the

ow pipeline.

2. Slowly close shut-o devices

 in the

return pipeline.

Settings

Dierential Pressure Setting (AHPBM-F)

AHPBM-F is controller with xed ∆p setting.

Therefore setting of ∆p is not required.

If the required dierential pressure is not

attained, a cause may be a too small

pressure loss in the system.

Flow Rate Setting (AHQM)

The ow rate is adjusted by means of

limitation of control valve stroke .

There are two possibilities:

1. Adjustment with the ow adjusting

curves,

2. Adjustment with heat meter.

Pre-condition

(Min. di. pressure over the valve)

To achieve maximum ow rate the pressure

dierence Δp

 across the control valve

must be at least:

p

min

= 0.5 bar

Adjustment with ow adjusting

curves

The system don’t need to be active for

being adjusted.

1. Close control valve

 by turning the

adjustable ow restrictor  to the right

 (clockwise) to its stop.

Adjustable ow restrictor  has to be

moved by hand not by tool.

2. Select ow adjusting curve in the

diagram (see page 4).

Necessary

ow rate

Revolutions of

adjusting throttle

3. Open the adjustable ow restrictor



by determined number of revolutions to

the left  (counter clockwise):

Adjustable ow restrictor  has to be

moved by hand not by tool.

4. The setting of the valve stroke is

completed, continue with step 2 in

section Adjustment with Heat Meter.

Note:

The setting may be veried with help of a

heat meter if the system is in operation,

see next section.

Flow Adjusting Curves

Adjustment with Heat Meter

Pre-condition:

The setting can be carried out when the

electrical actuator AMV(E) is dismounted.

The system must be in operation. All units

in the system  or a bypass must be

completely open.

1. Observe heat meter indicator:

- turning to the left (counter

clockwise)

 increases the ow rate

- turning to the right (clockwise)



decreases the ow rate

Adjustable ow restrictor  has to be

moved by hand not by tool.

After the adjustment has been completed

2. Install the electrical actuator

, see

section Mounting of electrical actuator.

3. Shortly throttle the system and then

re-open it (e.g. by means of the

electrical actuator).

4. Verify ow rate.

The control valve setting is completed.

5. Electrical actuator

 may now be

sealed

.
