4. Intended Use
The intended use as field of application of the DELTA SW4 single
seat and change-over valves is the shut-off of line sections,
especially in beverage and food installations.
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
- leakage
- destruction.
Failures in the production process are possible.
Warning!
The valve is suitable for use in hazardous areas
as identified on the valve according to Directive 2014/34/EU.
Arbitrary, constructive changes at the valve will influence safety
as well as the intended functionality of the valve and are not
permissible.

5. ModeofOperation
5.1. 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:
NC: actuator normally closed / air-to-raise, spring-to-lower
NO: actuator normally open / air-to-lower, spring-to-raise
- The inner parts of the actuator need not be serviced.
- The SW4 valve is equipped with a valve position indicator.
The proximity switches to signal the final position of the valve disc
can be mounted to the proximity switch holder (PSH).
The use of valve position indicators which are approved for the
application in explosive atmosphere is compulsary.
The use and operation of valve position indicators shall be
evaluated by the operator of the installation!
Assembly, see item 13.3.

6. Cleaning
6.1. Cleaningrecommendation
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veried.
7. Installation
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 7.2.
Conductive connection to the pipeline must be provided.
The integration into the operational potential equalization must be
guaranteed!

7. Installation
7.2. 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.
