4. Mode of Operation
4.1. General terms
Use of high-quality stainless steel and seal materials to the
  speciedrequirements,thedoublesealvalvewithdiaphragm
and “fan support” DELTA SDMS4 is applicable in the food and
beverage industries as well as in the pharmaceutical and
chemical sector.
Double seal valves with diaphragm offer optimum protection
of the product in hygienic and aseptic applications. Product safety
is achieved by the hermetic separation of the product chamber
  totheoutside(atmosphere)bymeansofaexiblediaphragm
with “fan support”.
- Leakage at the diaphragm is shown via a leakage indicator
in the yoke area.
  TheeldofapplicationoftheDELTASDMS4comprisesthe
safe shut-off and separation of line sections being separated
from one another by two seat seals. A leakage chamber is
arranged between the seals, the leakage chamber being forcibly
closed by the two leakage valves or opened to the atmosphere.
- Leakage at the seat seals is discharged via the leakage valves
to the atmosphere and indicated.
- Operation by pneumatic actuator with air connection.
The actuator is generally mounted normally closed (NC).
- The inner parts of the actuator are maitenance-free.
- To avoid pressure hammers, the valve should be closed against
  theowdirectionoftheuid.
- As standard design a control unit DELTA CU41N with NOT
element is installed on top of the actuator for the pneumatic
  controlofthevalve.TheNOTelementfulllsthetasktoincrease
the closing forces of the closed valve.
- The luminous diodes in the control unit indicate the position
of the valve shaft.
- Observe service instructions to ensure safe maintenance of
the valve.

5. Auxiliary Equipment
5.1. Valve position indication (fig. 5.1.)
A proximity switch holder for the valve position feedback can be
installed direct on the actuator.
Proximity switches to signal the limit position of the valve seat
can be installed at the proximity switch holder (PSH) if required.
We recommend to use APV standard proximity switches.
Operating distance : 5 mm / diameter : 11 mm.
Operating voltage: 10 - 30 VDC
Output: operating current pnp positive switching
Connection: moulded cable 5 m length
Protective class: IP 67

If the customer decides to use a different valve position indicator,
we cannot take over any liability for a faultless function.

6. Cleaning
6.1. Cleaning recommendation
For the cleaning of SDMS4 valves distiction is made
between two areas.
- Flow areas
The passages of the valve are cleaned by the cleaning liquid
during cleaning of the connected pipelines.
- Leakage chamber
Cleaning of the leakage chamber is undertaken via the
leakage valves. The cleaning liquid is supplied via
one leakage valve and discharged to the atmosphere via the
second leakage valve.
The restraint passage of the cleaning liquid provides for
perfect cleaning of the whole leakage chamber.
Depending on the degree and constituents of soiling, the cleaning
liquids, times and processes must be scheduled for the individual
application.
The compatibility of the individually selected cleaning processes
  andliquidswiththerespectivelyusedsealsmustbeveried.
Under normal conditions, 15 valves DN 25/1” - 100/4”
can be cleaned via one spray distribution line DN 25.

7. Installation
7.1. General terms
 Installationhastobedoneinsuchawaythatuidscandrain
off the valve housing and is preferably to be realized in vertical
position.
Attention: Observe welding instructions.
7.2. Welding Instructions
- Before welding of the valve, the valve insert and the leakage valves
must be dismantled from the housing. Careful handling to avoid
damage to the parts is necessary.
- Weldingshouldonlybecarriedoutbycertiedwelders (DIN EN ISO
9606-1) (Seam quality DIN EN ISO 5817).
- Welding of the valve housings must be undertaken in such
a way that the valve body is not deformed.
- The preparation of the weld seam up to 3 mm thickness must be
carried out as a square butt joint without air. (Consider shrinkage!)
TIG orbital welding is best!
- Afterweldingofthevalvehousingsorofthematinganges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 non-observance of these welding
instructions is not subject to our guarantee.
- For aseptic applications observe Welding Directives according to
AWS/ANSI and EHEDG.

10. Maintenance
The maintenance intervals depend on the corresponding
application and are to be determined by the user himself carrying
out temporary 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.
Replacement of seals according to Service Instructions.
Customer stock keeping of spare seals is recommended.
For valve service we supply complete seal kits including
seal grease (see spare parts lists)..
Required tools:
1x wrench SW13
1x wrench SW17
1x wrench SW19
1 x wrench SW30
1x hexagon socket wrench 6 mm
cleaning rag as well as a low solution of a suitable cleaning liquid
(observe safety data sheet of cleaning liquid producer).
Installation of seat seal see pages 19-20
- Provide all seals with a thin layer of grease before their installation!
- Provide the diaphragm at the product-averted side with a thin layer
of grease.
Recommendation:
APV assembly grease for EPDM, FPM, HNBR and NBR
(750 g/ tin - ref.-No. 000 70-01-019/93; H147382)
(60 g/ tube - ref.-No. 000 70-01-018/93; H147381)
Attention! Less suited grease types can inuence function
and lifetime.
Recommendation: screw locker
