3. Intended Use
The intended use as field of application of the DELTA DELTA UF3
relief valve is to prevent the max. product pressure from being
exceeded or to discharge a certain product quantity.
Attention:
In the sense of the Pressure Equipment Directive 2014/68/EU, the
DELTA UF3/UFR3 relief valve is a "pressure-retaining component"
and is not a "component with safety function", i.e. the valve must
not be used as safety valve.
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.
Arbitrary, constructive changes at the valve will influence safety
as well as the intended functionality of the valve and are not
permissible.

4. Mode of Operation
4.1. General terms
The valve has 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 APV UF3/UFR3 relief valve is used to prevent a desired
product pressure from being exceeded due to process requirements
or to discharge a certain product quantity.
If the preset opening pressure is exceeded, the valve is opened
automatically by the imminent line pressure in the supply line (A)
under the valve seat. The liquid is drained via the discharge line (B).
If the adjusted set value falls short, the valve is closed by spring
force.
The flow direction is always from A B.
Attention:
In the sense of the Pressure Equipment Directive 2014/68/EU, the
DELTA UF3/UFR3 relief valve is a "pressure-retaining component"
and is not a "component with safety function", i.e. the valve must
not be used as safety valve.
Proximity switches to signal the valve position can be installed in the
yoke area (C).

5. Auxiliary Equipment
5.1. Seat lift actuator (fig. 5.1)
The UF3 valve can be equipped with a seat lift cylinder if required
for cleaning technical reasons. (see chapter 6.)
5.2. Valve position indication
For the valve position indication, proximity switches can be installed
in the yoke area.
We recommend to use our APV standard types:
Operating distance: 5mm / Diameter: 11mm.
If the customer decides to use a valve position indication other
than APV type, we cannot take over any guarantee for a faultless
function.
5.3. Valve seat variants (fig. 5.3.)
Valve seat in at and conical design, for special requirements, are
available. Through the use of a valve seat with regulating cone,
the ow behaviour at low ow quantities is improved and a "softer"
valve closing is achieved.
The valve variant is called "UFR3".
5.4. Housing configurations (fig. 5.4.)
Different housing shapes can be applied to reduce dead spaces to a
minimum.
* The spring cylinder is available with scale and hand wheel to allow
for a simple adjustment of the response pressure (g. 5.5.).
* As a special version, the pressure relief valves are available in
aseptic design (with at diaphragm or metal bellow).
- Deviations from the standard spare parts lists result. These special
drawings and spare parts lists will be supplied separately.

6. Cleaning
Optimum cleaning is given if the seat lift actuator (E) drives
the valve seat into the position “on” during the cleaning process
(fig. 6.1).
During this process, the cleaning liquid can flush the seal
surfaces.
After termination of the cleaning step, the seat lift actuator is vented
and the valve seat moves into "closed" position by spring force.
6.1. The flow chambers
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 has to be done in such a way that liquids can drain off
the valve housing. Vertical position is preferred.
Valves can be welded direct into the pipeline (valve insert
completely dismantable).
- After the installation, the set value must be adjusted by a pressure
gauge.
Adjustment: turn right = pressure increase
turn left = pressure reduction
If required, the value can be corrected during production
by turning the adjusting screw at the spring cylinder.
Attention! Observe Welding Instructions 7.2.
7.2. Welding Instructions
- 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 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.
