NOTICE
2. PRODUCT INFORMATION
The ADCA RP45 series pressure reducing valves are single seated, bellows sealed
proportional controllers that operate without auxiliary energy. These are used in industrial
applications to maintain the pressure downstream of the valve within acceptable limits
of the adjusted set point.
These valves are specially designed for use with steam, compressed air and other gases
compatible with the construction and have limited use with liquids.
The regulator is used in conjunction with a diaphragm (45) or piston actuator (connected
to each other through a sensing pipe) which is either supplied pre-assembled onto the
valve or delivered separately. If delivered separately, the actuator should be assembled
according to these Installation and Maintenance Instructions (IMI).

IMI RP45.015 E 00.23
The valve is supplied with the adjustment spring (18) slightly pre-compressed.
The sensing pipe (40) can be supplied separately or pre-assembled from the factory, in
which case it is connected directly onto the valve outlet port. When supplied separately,
it is meant for connection onto the pipeline downstrean and should be installed at a
minimum of 1 meter or 15 pipe diameters away from the valve outlet.
A seal pot (46) is tted on the sensing pipe when operating with steam or liquids at
temperatures above 90 ºC, protecting the actuator diaphragm and/or seals against
overheating. The sensing pipe and seal pot are lled with the process medium in such
case (in steam application, water is used).
The process medium enters the valve body in the direction indicated by the arrow and
while there is no backpressure, the valve is kept open and the medium ows between
seat (2) and plug (4). The downstream pressure starts to rise and is transmitted through
the sensing pipe (40) into the actuator (45).
The pressure force in the actuator chamber pushes the stem (3) and valve plug toward
the seat, closing the valve. The adjustment spring compression is adjustable and its
force acts against the actuator. Compression of the adjustment spring causes increase
in downstream pressure and vice versa.
Under stable conditions the actuator force and spring force are balanced against each
other.
When downstream pressure changes due to ow demand, so does the pressure inside
the actuator and unbalancing of forces occurs causing the valve to respond by opening
or closing. The valve closes when downstream pressure rises and vice versa, regulating
ow to keep downstream reduced pressure stable.
Sealing of the valve stem is made via bellows (10) which serves the additional purpose
of balancing the forces on the valve plug.
The valve has limited use with liquids because the plug closes in the direction of the uid
ow, which can produce vibrations and hammers. To avoid this, the valve can be installed
with the uid direction against the plug under certain conditions. However, it is suggested
to consult VALSTEAM ADCA before installing the valve with liquids. Alternative models
are also available for reducing service in liquid applications.

4.1. Preparation for installation
Before installation, make sure the following conditions are met:
• The installation area has easy access and the device is to be installed in a position
where operation and maintenance work can be performed safely.
• The product will be installed with proper support and free of any stresses that can
be induced by the system due to e.g. pipe expansions. The necessary precautions
are recommended during system design.
• The pipeline where the product will be installed is designed in such a way that it
takes into account the weight of the product. The pipeline may require support on
both sides next to the product, particularly if its size and weight are considerable
and especially if vibrations are to be expected in the system.
• The product is not damaged.
• Make sure all the necessary materials and tools are readily available during
installation work.
• Referring to these Installation and Maintenance Instructions (IMI), Information Sheet
(IS) and nameplate, check that the product is suitable for the intended installation:
temperature, medium, pressure, temperature, etc. – see section 1.2 – Intended
use.
• Check that there are no foreign bodies inside the pipelines and ancillaries, ushing
may be necessary. These should be thoroughly cleaned.
• An ADCA pipeline strainer or lter should be installed upstream of the pressure
regulator, preventing solid particles from the process medium from damaging the
product.
• It is recommended that a suitable safety valve is tted on the downstream side
of the pressure regulator in order to protect downstream equipment from over
pressure. The valve should be set at a pressure below the safe working pressure
of the downstream equipment and sized according to the maximum capacity of the
pressure regulator should it fail in the fully open position. Ensure the safety valve
outlet pipe is connected to a safe place.
• There are pressure gauges installed both upstream and downstream of the
regulator. These will be used for monitorization, downstream set point adjustment
and, if necessary, troubleshooting. Check that these devices function properly.
• In steam service applications, the pressure reducing valve should be positioned
where condensation is unable to collect or that, alternatively, a humidity separator
with accompanying steam trap station is tted so that the pipeline drains correctly.
Slope the pipeline upstream and downstream of the regulator if necessary.
• A bypass line can be tted to prevent system shutdown during maintenance
procedures. In that case a globe valve with regulating plug should be tted in the
bypass line to allow manual adjustment of downstream pressure.
• If the sensing pipe is not tted onto the valve body, it must be installed downstream
at a minimum of 1 meter or 15 pipe diameters away from the valve outlet. The

ADCA
14
VA L STEAM
ADCA
IMI RP45.015 E 00.23
sensing pipe should be 10mm diameter copper or stainless steel. Weld a 3/8”
threaded coupling at the side in the middle of the pipeline. In case of steam or
gases service the sensing pipe may also be welded on the top of the pipeline. An
ADCA seal pot must be installed in the sensing pipe when operating with steam or
liquids at temperatures above 90 ºC.
For reference on the conguration of a typical pressure reducing station, consult
the assembly drawing ADCR.04.3055.
NOTE
4.2. Mounting the actuator onto the valve
Pressure regulators are typically delivered as an assembled unit, with the actuator
already mounted. When delivered separately these must be assembled together either
before installing the regulator in the pipeline or before starting up.
Proceed as follows for valves DN 15 to DN 100 or NPS ½" to 4":
1. Screw the lock nut (24) on the bonnet until reaching the end stop.
2. Position the actuator on top of the bonnet assembly (15, 15A).
3. Fix the actuator onto the valve bonnet by screwing it (clockwise). As the actuator
housing touches the lock nut, unscrew the actuator by no more than a full turn until
the compression tting (60) is square with the valve outlet connection.
4. Screw the lock nut (24) tightly against the actuator housing, tightening with the
recommended torque – see section 9.6 – Tightening torques.
Proceed as follows for valves above DN 100 or NPS 4’’:
1. Insert the guide (54A) of the actuator through the central hole of the pillar ange
(29).
2. Align the compression tting (60) with the valve outlet connection.
3. Secure the actuator in place by screwing the lock nut (31) onto the guide (54A),
tightening with the recommended torque – see section 8.6 – Tightening torques.
4.3. Installation procedure
1. Remove plastic lm and other packaging, as well as the protective covers which
are placed on anges or connection ends. Make sure the pressure regulator is free
from foreign matter.
2. The recommended installation position is horizontal, with the actuator vertically,
pointing downwards. Installation with the actuator pointing upwards (above the
pipeline) is possible only when the medium temperature is below 90 ºC.
3. The pressure regulator has an arrow or inlet/outlet designation, be sure that it is
installed in the appropriate direction according to uid ow.

IMI RP45.015 E 00.23
4. If the sensing pipe is not tted onto the valve body, it must be installed downstream
of the valve at a minimum of 1 meter away or 15 pipe diameters. The connection on
the downstream pipeline must be at the top or at the side. Do not remove the ow
restrictor (58) from the actuator.
5. The seal pot must be installed in the sensing pipe when operating with steam or
liquids at temperatures above 90 ºC. The installation position of the seal pot is with
the inlet and outlet connections in the vertical plane and the eccentric plugged port
on the top.
6. Take care with jointing materials and sealing compounds to ensure that none may
be permitted to block or enter the pressure regulator, causing malfunction. In case
of anged connections use appropriate ange gaskets.
7. If the valve is to be thermally insulated, only insulate the valve body itself. Do not
insulate the adjustment spring, actuator, sensing pipe and seal pot, if tted.
5. START-UP
Before performing the start-up procedure, refer to section 1 – Safety information.
The start-up procedure must be followed every time the product is put back into service.
