2. Safety Instructions
Danger!
Welded actuators are preloaded by spring force.
Opening of the actuators is strictly forbidden.
Danger to life!
Actuators which are no longer used or defective must be disposed
in professional manner.
Defective actuators must be returned to your SPX FLOW
representative for their professional disposal and free of charge for
you.
3. Intended Use

4.1. General terms
Single seat and change-over valves DELTA SW4 have been
developed for use in the brewing and beverage, dairy and food
industries as well as for chemical and pharmaceutical applications.
The valves are designed for universal applications and stand out
for their increased mechanical reliability and absolute ease of
service.
The field of application of the DELTA SW4 valve is to shut off
and to change over line sections.
-Operation by pneumatic actuator with air connection, reset by spring
force.
-By different assembly of the actuator, the following designs are
possible:
-The inner parts of the actuator need not be serviced.
-As standard design, the SW4 valve is equipped with a control unit
CU41 Direct Connect.

fig. 5.2.
Proximity swith holders (PSH) for the valve position indication can
be mounted direct on the actuator. Proximity switches to signal
the limit position of the valve seat can be installed at the proximity
switch holder.
We recommend to use our APV standard types:
Operating distance: 5 mm / Diameter: 11 mm.
Operating voltage: 10 - 30 VDC
Outlet: operating voltage pnp positive switching
Connection: moulded cable 5 m length
Protective type: IP 67
Reference number: 08 - 60 - 011/93; H16223
Using a valve position idicator other than APV, we cannot accept
any liability for a faultless function.

5.3. Stroke limitation SW4 / M4 (fig. 5.3.)
The pneumatic stroke limitation provides for the continuous
adjustment of the total valve stroke of 0 - 100%.
The pneumatic stroke limitation is installed on the actuator.
The valve disc can be in the three different positions:
open, throttled and closed.
The stroke limitation can only be applied with valve design
NC (FS) = normally closed.
To operate the pneumatic stroke limitation a separate control is
required.
The control unit CU43-S-2 Hall sensors-Direct Connect
can be used for this purpose.

5.4. Oil dampening cylinder (fig. 5.4.)
The oil dampening cylinder provides for a slow opening and closing
of the valve (to prevent pressure hammers in the line system). The
oil dampener is installed between the actuator and the control unit.
Function:
During valve switching, a throttling valve presses the oil from one
chamber of the dampening cylinder into the second chamber of the
cylinder. By adjustment of the throttling screw, the required delay
can be variably adjusted.
5.5. SW4 variants
The SW4 range contains the following designs:
-DELTA SW4 - DN125-150
-DELTA SW4 with manual actuation
-DELTA SWT4 - tank outlet valve

6. Cleaning
6.1. Cleaning recommendation
-Flow passages
The passages of the valve are cleaned by the cleaning liquid during
cleaning of the connected pipelines.
Depending on the degree and substances of soiling, cleaning
liquids, times and processes must be scheduled for the individual
application.
The compatibility of the individually selected cleaning processes
and liquids with the respective seal material must be veried.
7. Installation
fig. 7.
change-over valve
separate connection
7.1. General terms
-Installation must be undertaken in such a way that liquids can drain
off and should preferably be carried out in vertical position.
-Single seat valve:
The valve housing can be welded direct into the pipeline system
(completely dismantable valve insert).
-Change-over valve:
The upper housing is connected with the pipeline via a ange or
clamp connection in detachable manner (see g. 7.).
Attention! Observe Welding Instructions 7.3.
7.2. Connections
Besides the basic version with weld ends, the valve housing are
also available with threaded, flange and clamp connection.

7. Installation
7.3. Welding Instructions
Shut-off valve
-Before welding of the valve, the valve insert must be dismantled
from the housing. Careful handling to avoid damage to the parts
is necessary.
Change-over valve:
-Before welding of the valves, the valve insert must be dismantled
from the housing. The lower housing seal must be removed.
Careful handling to avoid damage to the parts is necessary.
-Welding should 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 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 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 non-observance of these welding
instructions is not subject to our guarantee.
-Welding directives for aseptic applications shall be drawn from the
AWS/ANSI Directives and EHEDG Guidelines.

10. Maintenance
Scan for SW4 Valve
Maintenance Video
The maintenance intervals depend on the corresponding
application and are to be determined by the operator 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.
-Required tools:
- 1x wrench SW13
- 1x wrench SW17
- 1x wrench SW19
- 1x wrench SW30
- assembly tool for seat seal (see chapter 14.)
- Exchange of seals is done according to Service Instructions.
Customer stock keeping of spare seals is recommended.
For valve service actions we supply complete seal kits including seal grease (see spare parts lists).
Assembly of the valve and change of the valve design NC or NO according to Service Instructions.
Attention!Use food-grade grease and special greases being suited for the respective seal material, only!
! Do not use grease containing mineral oil for EPDM seals.
! Do not use Silicone-based grease for VMQ seals.
Less suited grease types can influence function and service life.

Control the valve with air.
5. Slide the protective tube over the thread of the guide rod.
Slide the shaft through the upper housing, yoke and actuator.
Place the centering washer and tighten the safety nut.
Hold up the safety nut during this process.
Tightening torque 40 Nm.

6.Attention: Valve design NO:
Shut off compressed air.
7. Install the adapter for the control unit on the actuator.
Apply a drop of a screw locker (e.g. type: Loctite semi-solid)
in the area of the threaded bore of the actuator screw.
Fasten actuator screw on the guide rod.
13.4. Installation of valve

- thrust ring
- ring with venting nose
- housing
- threaded bolt

1. Insert the valve shaft into the housing in such a way that
the seal groove is in the housing.
2. Clamp the shaft into the housing by means of the threaded bolt.
Clamp the housing in a vice.
3. Slightly grease the seat seal with APV assembly grease.
Then install the seal on the ring with the venting nose until it stops.
4. Introduce the ring with the installed seat seal into the housing and
press it down until it stops sensibly.
5. Insert the thrust ring into the housing. Screw on the nut and tighten
it with a hook spanner until it stops.
6. Release the nut. Take ring and thrust ring off the housing.
7. Take housing out of the vice, take off the threaded bolt.
Detach the valve shaft from the housing
Check the even fit of the seat seal.
To simplify the installation of the seat seal, the following assembly tools are available:

15. Reconstruction of Actuator
With SW4 valves, the size of the actuator can be changed.
Observe the respective line pressure, see table 9.6,
to increase or decrease the actuator sizes
(Ø 74 mm, Ø 110 mm, Ø 165 mm).
15.1. Reconstruction of actuator
Disassembly
Disassembly is carried out as described in chapter 11.
for single seat valves and in chapter 13. for change-over valves.
To change the actuator size, the respective guide rod (4)
must be replaced.
Attention!
Clamp the valve disc in a vice.
The valve disc must not be damaged (use protective cheeks or
cleaning rags). Even inferior damage at the shaft rod can lead to
leakages.
Turn the guide rod out of the shaft by means of the centering
washer and a wrench SW17.
15.2. Assembly of actuator
1. Turn the respective guide rod into the shaft to the actuator.
Tightening torque 40 Nm
2. Further assembly is undertaken in reverse order.
