directionsforoperatingsafety.Youwillnditwhereverthe 
activities described are bearing health hazards or risks for
persons or material assets.
-Do not reach into the open valve or yoke!
Risk of injury by suddenly operating valve. In dismantled state
there is the risk of bruising at movable parts of the valve.
Attention!
Valve design NC (normally closed): Control the actuator with
air before releasing the housing screws.
- Before any maintenance work, the line and cleaning system must
be depressurized and discharged if possible.
- If the diaphragm is damaged, leakges will emerge from the leakage
bore in the yoke area.
- Electric and pneumatic connections must be separated.

4. Mode of Operation
4.1. General terms
DELTA MS4 diaphragm valves have been designed for
use in the brewing and beverage industries, in the dairy and food
industries as well as for chemical and pharmaceutical applications.
TheeldofapplicationoftheDELTAMS4valvecomprisesthesafe
shut-off of pipeline sections.
Diaphragm valves offer optimum product protection in hygienic and
aseptic applications. Product safety is provided by the hermetic
separation of the product chamber to the exterior (atmosphere) by
means of a diaphragm with fan support.
The standard MS4 valve series is equipped with a valve
position indication.
As an option, a control unit can be installed on the actuator.
- Operation by pneumatic actuator with air connection, reset by spring
force. iThe actuator is generally mounted in normally closed (NC)
manner.
- Through different assembly of the actuator, the following designs
are possible:
NC: actuator normally closed (NC); air-to-raise, spring-to-lower
NO: actuator normally open (NO); air-to-lower, spring-to-rais
- The inner parts of the actuator are maintenance-free.
- In order to prevent pressure hammers, the valve should be closed
againsttheowdirectionofthemedium.
- Leakages at the diaphragm are indicated in the yoke area through a
leakage drain.
- Different valve designs are available:
Single seat valves: DELTA MS4
DELTA MSP4
(with diaphragm shaft made of PTFE)
DELTA MSR4
(with regulating cone)
Tank outlet valves: DELTA MST4
DELTA MSTP4
(with diaphragm shaft made of PTFE)

5. Auxiliary Equipment
5.1. Valve position indication (fig. 5.1.)
For the valve position indication a proximity switch support can be
installed direct at 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 one of our APV standard types:
operating distance : 5mm / diameter: 11mm.
Operating voltage: 10 - 30 VDC
Output: operating current pnp - positive switching
Connection: moulded cable 5 m long
Protective type: IP 67
Reference number: 08 - 60 - 011/93; H16223
If the customer decides to use a valve position indicator other than
APV type, we cannot take over any liability for any malfunctions.
5.2. Control Unit (fig. 5.2.)
The installation of a control unit on the MS4 valve is possible.
The following different designs are available:

6. Cleaning
6.1. Cleaning recommendation
Flow areas
The passages of the valve are cleaned by the cleaning liquid
during cleaning of the connected pipelines.
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
Installationhastobeundertakeninsuchawaythatuidscandrain
off the valve housing and should preferably be done in vertical
position.
- The valve housing can be welded direct into the pipeline
(completely dismantable valve insert).
Attention! Observe welding instructions.
7.1. Welding Instructions
MS4
- Before welding of the valve, the valve insert 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
ISO9606-1). (seam quality DIN EN ISO 5817)
- The 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 in butt manner 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 or
pipeline 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.
- Welding directives for aseptic application areas of the AWS/ANSI
regulations and EHEDG guidelines must be observed.

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).
