2. Safety Instructions
Danger!
Depressurize and, if possible, discharge the line and cleaning
system before any maintenance work.
Do not touch the yoke area or actuating area (positioner) when the
valve is installed. Risk of injury through sudden valve operation.
Electric and pneumatic lines must be disconnected before assembly
or disassembly of the valve (e.g. for seal replacement).
Do not reach into the valve body when the valve is dismantled.
Observe instructions given for valve in installed state.
Regular maintenance including replacement of all seals,
diaphragms and guide bushings must be scheduled in order to
prevent leakages.
Incaseofdamageofthediaphragm,uidswillleakfromthe
leakage bore in the yoke area. Leakages must be drained safely.
Riskofburn
Topreventpersonalinjury,thevalvesmustnotbetouched
duringCIPcleaningorsterilizationwithhotwaterorsteam.
Observe Service Instructions to ensure safe maintenance of the
valve. The valve must only be assembled, disassembled and

4. Intended Use
The intended use as field of application of the APV DELTA RGMS4
asepticmodulatingvalveistheflowandpressurecontrolofliquids
and gases.
Arbitrary, constructive changes at the valve will influence safety
as well as the intended functionality of the valve and are not
permissible.
Its use is permissible only within the admissible pressure and
temperature margins and under consideration of chemical and
corrosive influences.
Any use exceeding the margins and specifications set forth,
is considered to be not intended.
Any damage resulting therefrom is not within the responsibility
of the manufacturer.
The user will bear the full risk.
Attention!
Improper use of the valve leads to:
- damage

5. ModeofOperation
5.1. Generalterms
- Aseptic modulating valves RGMS4 can be used for the continuous
regulationofmaterialowsinthebeverageandfoodindustriesand
in chemical and pharmaceutical applications.
- Themodulatingvalvesaresuitedfortheowandpressure
regulationofuidsandgases.
- An optimum protection of the product in hygienic and aseptic areas
is guaranteed.
- At the shaft passages product safety is reached by the hermetic
separation of the product chamber from the outside (atmosphere)
byaexiblediaphragm.
- In its basic shape, the Delta RGMS4 is designed as a corner
valve.Therefore,thevalveprovesfavourableowdeviation
characteristics.TheowdirectionisfromAtoB(g.1).
- The housing which is free of dead spaces has optimum cleaning
features. Crevice-free sealing of the individual housing parts by
proleseals-nosourceofinfection.
- Leakages at the diaphragm are indicated in the yoke area via a
leakage drain (L).
- Theinterdependencebetweenowandconestrokeisdenedby
the characteristics.
- Differentkvsvalues(ow)withacertainvalvedimensioncanbe
reachedbydifferentinserts(valveseat/valvecone).(g.1)
- The table in Item 12. shows the parts to be changed in case of
modicationofthekvsvalue.
- The connections (G) or the electric and pneumatic supply are
located laterally at the positioner (C).
- An optical position indication (stroke indication) is located in the
yoke area (E).

5. ModeofOperation
5.2. Actuator
- 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denesthepneumaticactuatingpressureasoutputsignal.
- Dependingonthespecicrequirement,themodulatingvalvecanbe
operated either in normally open or in normally closed design.
MFS - diaphragm actuator normally closed
The actuator opens with actuating pressure and closes by spring
pressure.
MFH - diaphragm actuator normally open
The actuator closes with actuating pressure and opens by spring
pressure.
- For the different applications, the diaphragm actuators are supplied
with different actuating pressures.
The positioner is an electro-pneumatic transformer. The direction
ofowstransferredcanberising(directionalequality>>)orfalling
(directionalreverse<>).

6. Cleaning
6.1. Theflowchambers
Thepassagesofthevalvearecleanedbythecleaningliquidduring
cleaning of the connected pipelines.
The compatibility of the individually selected cleaning processes
andliquidswiththerespectivelyappliedsealmaterialmustbe
veried.
7. Installation
- The Delta RGMS4 valve must be installed in such a way that
productsandcleaningliquidscandrainoffthevalvehousing.
Priority should be given to a vertical installation.
Attention! Observe welding instructions!
Conductive connection to the pipeline must be provided.
Theintegrationintotheoperationalpotentialequalizationmustbe
guaranteed!
7.1. WeldingInstructions
RGMS4
- Before welding of the valve, the complete valve insert must be
dismantled from the housing. Careful handling to avoid damage to
the parts is necessary.
- Dismantlethematingangesfromthevalvehousingandremove
theangeseals.Justtackingoradjustmentofthematinganges
shouldbeundertakenwithxedvalvehousing.
- Welding should only be carried out by certified welders (DIN EN ISO
9606-1)(seamqualityDINENISO5817).
- The preparation of the weld seam up to 3 mm thickness shall be
carriedoutasasquarebuttjointwithoutair.(Considershrinkage!)
- TIG orbital welding is best!
- Afterweldingofthevalvehousingorofthematingangesandafter
work at the pipelines, the corresponding parts of the installation
and 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 non-obeservance of these welding
instructions is not subject of our guarantee.

11. Maintenance
- The maintenance intervals depend on the corresponding application
and are to be determined by the operator himself carrying out
temporary checks.
- Before start of maintenance and assembly the operator must make
sure that an explosive atmohsphere does not exist (detection/
measurement of potential concentration of hazardous substances).
Alternatively, use spark-resistant tools!
The valve must not be cleaned with products containing abrasive
or polishing material. Especially the valve shaft must not, under any
