This instruction manual should be read carefully by the
competent operating and maintenance personnel.
We point out that we will not accept any liability for damage or
malfunctions resulting from the non-compliance with this
manual.
Descriptions and data are subject to technical changes.
2. Safety Instructions
DANGER!
- The technical safety symbol draws your attention to important
directions for operating safety. You will find it wherever the
activities described are bearing riks of personal injury.
- Do not reach into the yoke area or into the actuating area
(valve positioner) when the valve is installed. Risk of injury by
sudden valve actuation.
- Electric or pneumatic lines must be disconnected before assembly
or disassembly of the valve (e.g. for seal exchange purposes).
- Do not reach into the valve body when the valve is dismantled.
Otherwise, observe the instructions given for the installed
valve state.
3. Mode of Operation
- ygienic modulating valves DELTA RG4 are used for the
continuous control of liquid flows in beverage and food
technology as well as in the chemical and pharmaceutical
industry. Modulating valves are suited for the flow and
pressure control of liquids and gases.
- In its basic construction, the DELTA RG4 valve is designed as
corner valve and, thus, ensures a good diversion of liquid flows.
The flow direction is from Ato B(see fig. 1).
- The body being free from dead spaces proves optimum cleaning
conditions. The crevice-free sealing of the individual parts of the
body is effected by profile seals, thus eliminating any source of
infection.
- The relation between flow and cone stroke is defined by the
characteristics.
- Different kvs values (flow) at certain nominal dimensions can be
reached by different inserts (valve seat / valve cone).

- The table (item 11) shows the parts which have to be replaced
if flow rates are changed. The design of the valves with regard
to the actuating pressure range or flow rate is made by the
manufacturer.
- The connections for the electric and pneumatic supply lines are
located at the valve positioner (E).
The pneumatic actuator (D) provides the path and the force to
open or to close the control element. The diaphragm actuator
is suited for longer actuating distances at minimum self-friction.
The valve positioner (C) guarantees the preset coordination
between valve position and control signal. It compares the control
signal (4-20 mA) given by the control device with the stroke of
the control element and defines the pneumatic actuating pressure
as output signal.
Depending on the specific requirement, the modulating
valve can be operated either with spring opening or with spring
closing function.
MFS - diaphragm actuator, spring closing
The actuator opens by actuating pressure and closes by spring
pressure.
MFH - diaphragm actuator, spring opening
The actuator closes by actuating pressure and opens by
spring pressure.
For the various applications, the diaphragm actuators are supplied
with different diaphragm surfaces and different actuating pressures.
In its standard design, the valve positioner is a electro-pneumatic
transformer. A pneumatic valve positioner (control signal 0.2-1.0
bar) is also available for specific operations.
The direction of flows transferred can be
rising (directional equality >>) or falling (directional reverse <>).
The valve positioner can be installed in two different ways:
1) valve positioner integrated in the diaphragm actuator;
the feedback of the valve position is effected as mechanical tap
at the valve shaft within the integrated positioner (fig. 1).
2) valve positioner according to NAMUR (fig. 2);
the positioner is installed at the valve yoke by means of a rib.
The feedback of the valve position is effected via the operating
cam with fastening plate installed at the valve shaft.
Valve position indication can also be effected in the positioner -
either by indication of the valve end position or by an analog
feedback for the whole stroke range (4-20 mA).

The intended use as field of application of the DELTA RG4
modulating valve is the continuous control of liquid flows in beverage
and food technology as well as in the chemical and pharmaceutical
industry.
Arbitrary, constructive changes at the valve will influence safety as
well as the intended functionality of the valve and are not permissible.

5. Installation
- The DELTA RG4 must be installed in such a manner that the
product or the cleaning liquid can drain off the valve housing.
Priority should be given to a vertical installation.
- Attention ! Observe Welding Instructions.
5.1 Welding Instructions
- Before welding, the flanges must be dismantled from the valve
housing, just tacking or adjustment of the valves should be carried
out with fixed flanges.
- Welding may only be carried out by certified welders (DIN EN ISO
9606-1). (Seam quality DIN EN ISO 5817).
- The welding of the valve housings must be undertaken in such a
way that deformation strain cannot be transfered to the valve body.
- The preparation of the weld seam up to 3 mm thickness must be
carried out in butt manner as an square butt joint without air.
(Consider shrinkage!)
- TIG orbital welding is best!
- After welding of the valve housing or of the mating flanges and
after work at the pipelines, the corresponding parts of the
installation or pipelines must be cleaned from welding residues
and soiling. If these cleaning instructions are not observed,
welding residues and dirt particles can settle in the valve and
cause damage.
- Any damage resulting from the nonobservance of these welding
instructions is not subject to our guarantee.
- Welding directives for aseptic applications shall be drawn from the
AWS/ANSI Directives and E EDG Guidelines.

valve shaft (26) out of the housing cover (9).
5. Release hexagon screw (13) and take housing cover from the
valve yoke (12).
6. Remove seat seals (27) from valve shaft (cone).
Loosen head of coupling (33) and counternut (23) from
valve shaft (26).
Note: Observe adjusting dimensions between counternut
and valve shaft!
7. Remove housing seals (8) from valve seat (28) and from
housing cover (9).
8. Remove shaft seal (10) from housing cover (9), remove
bushing (11) from yoke (12).
9. Remove flange seals (3) from housing (1) and dismantle
housing flange (5).
10.3. Disassembly of the valve for change of flow rate and
characteristics
1. See chapter 9.2. items 1. - 4.
2. If, in case of change of flow rates, the diaphragm actuator
(32 / 35) must also be exchanged, remove air hose (19),
loosen nut by means of hammer and chisel and take off actuator.
3. Loosen head of coupling (33) and counternut (23) from the
valve shaft (26).
(Note: Observe adjusting dimensions of counternut and valve
shaft!).

10.4. Assembly of the valve and installation of new parts
CAUTION!
To ensure a trouble-free assembly and a high service life of all wear
parts (seals, guides, etc.), all parts must be slightly greased.
Sharp-edged tools (screwdrivers or similar tools) must not be used
for the installation to avoid damage to the parts and provide their
faultless function.
1. Place housing seal (8) onto the valve seat (28) and insert
seat into housing (1).
2. Insert flange seals (3) into the housing flange (to 1) and into
the flange (5) and install the housing (1) in the line system by
means of screws and nuts (4, 6, 7).
CAUTION!
Provide for proper alignment of housing and line flanges!
3. Insert seat seal (27) into valve shaft (26).
CAUTION!
To prevent air from being trapped in the groove, use suitable tool
to vent the groove.
4. Insert shaft seal (10) into the housing cover (9).
Insert bushing (11) into the yoke (12).
Tighten cover (9) with the valve yoke (2) by hand.
5. Place housing seal (8) on the housing cover (9).
6. Insert valve shaft into the valve yoke. Screw counternut (23) and
coupling (33) on the thread of the valve shaft (26). Connect the
valve shaft and actuator rod of the diaphragm actuator by means
of the coupling. (For NAMUR installation, slide the carrier pin of the
positioner (21) into the fastening plate.)
CAUTION! (FOR NAMUR INSTALLATION)
In case of different operating modes of the diaphragm actuator
(MFS or MF ), the position of the valve positioner as against the
fastening plate is also different.
7. Push valve insert into the housing and fasten it at the housing
flange by means of the hexagon nuts (14).
8. Firmly tighten coupling and hexagon nuts (13).
9. Connect electric and pneumatic supply lines.
