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
operating manual.
Descriptions and data given herein are subject to
technical changes.
2. Safety Instructions
DANGER!
- The technical safety symbol draws your attention to important
directions of operating safety. You will find it wherever the activities
described are bearing risks of personal injury.
- 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.
- In case of damage of the diaphragm, fluids will leak from the
leakage bore in the yoke area.
- Attention: 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
reassembled by persons who have been trained in APV valves or
by SPX FLOW service team members. If necessary, contact your
local SPX FLOW representative.

3. 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.

4.1. General Information
- Aseptic modulating valves RGMS4 can be used for the continuous
regulation of flows in the beverage and food industries and in
chemical and pharmaceutical applications.
- The modulating valves are suited for the flow and pressure regulation
of fluids 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 flexible diaphragm.
- In its basic shape, the Delta RGM4 is designed as a corner valve.
Therefore, the valve proves favourable flow deviation characteristics.
The flow direction is from Ato B (fig. 1).
- The housing which is free of dead spaces has optimum cleaning
features. Crevice-free sealing of the individual housing parts by
profile seals - no source of infection.
- Leakages at the membrane are indicated in the yoke area via a
leakage drain (L).
- The interdependence between flow and cone stroke is defined by
the characteristics.
- Different kvs values (flow) with a certain valve dimension can be
reached by different inserts (valve seat / valve cone). (fig. 1)
- The table in Item 12. shows the parts to be changed in case
of modification of the kvs value.
- The connections (C) or the electric and pneumatic supply are
located laterally at the positioner (G).
- An optical position indication (stroke indication) is located in the
yoke area (E).

4. Mode of Operation
4.2. 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 defines the pneumatic actuating pressure as
output signal.
- Depending on the specific 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 various applications, the diaphragm actuators are
supplied with different actuating pressures.
- In its standard design, the valve positioner is an electro-pneumatic
transformer. A pneumatic valve positioner 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 is integrated in the diphragm actuator;
The feedback of the valve position is effected as mechanical tap
at the valve shaft within the integrated positioner (fig. 2).
2) valve positioner according to NAMUR;
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 (fig. 3).
- Valve position indication can also be in the positioner; either by
indication of the valve final position or by an analog feedback for
the whole stroke range.

- 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!
5.1 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 flanges from the valve housing and remove
the flange seals. Just tacking or adjustment of the mating flanges
should be undertaken with fixed 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 flanges 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.

9. Maintenance
Maintenance intervals depend on the application and must be
decided by the operator himself carrying out regular checks.
- The valve must not be cleaned with products containing abrasive
or polishing material. Especially the valve shaft must not, under any
circumstances, be cleaned with such agents.
Damage of the valve shaft can lead to leakages.
- The customer is recommended to hold spare seals and diaphragm
on stock. For valve maintenance SPX FLOW supplies complete
seal kits (pl. see spare parts lists)
- Required tools:
1 x spanner SW13
1 x spanner SW17
1 x spanner SW19
1 x spanner SW24
1 x spanner SW30 (1.5")
1 x screw driver small and medium
- If damaged seals are dismantled, generally all seals and the
diaphragm should be replaced.
- Assembly and disassembly as well as replacement of
seals / diaphragm, see Service Instructions.
- Provide all seals with a thin layer of grease before their
installation.
Recommendation:
APV assembly grease for EPDM, HNBR and FPM
(0.75 kg /tin - ref.-No. 000 70-01-019/93; H147382)
(60 g /tube - ref.-No. 000 70-01-018/93; H147381)
or
APV assembly grease for VMQ
(0.6 kg /tin - ref.-No. 000 70-01-017/93; H147380)
(60 g /tube - ref.-No. 000 70-01-016/93; H147379)
! Do not use grease on mineral oil basis for EPDM seals.
! Do not use Silicone-based grease for VMQ seals.
!No matter what type of application, use only those greases
being suited for the respective seal material.
Recommendation for screw retention
Type: Loctite 243 semi-solid
(50 ml - ref.-No. 00070-01-111/93; H206336)
