1. General Terms

Relief Valve

DELTA UF 3 (A) / UFR3 (A)

Operating Manual: Rev.5

DELTA UF3-UK5.qxp / 06.2008

This operating manual has to be read carefully and observed by

the competent operating and maintenance personnel.

We have to point out that we will not accept any liability for

damage or malfunctions resulting from the non-compliance

with this operating manual.

Descriptions and data given herein are subject to technical

changes.

2. Safety Instructions

Danger!

- The technical safety symbol draws your attention to important

directions of operating safety. You will find it wherever the activities

described are bearing risks of personal injury.

- Disconnect electrical and pneumatic connections.

- Depressurize the line and cleaning system and discharge the lines,

if possible, before any maintenance work.

-Risk of injury by sudden valve actuation!

- Observe service instructions for a safe maintenance of the valve.

- The valve must only be assembled, disassembled and

reassembled by persons who have been trained in APV valves

or by APV service team members. If necessary, contact your local

APV representative.

- The spring cylinders are preloaded by spring force.

Opening of the actuators is strictly forbidden.

Danger to life!

Actuators which are no longer used and / or defective

must be disposed in professional manner.

Defective actuators must be returned to your

APV Solutions & Services company

for their professional disposal and

free of charge for you.

Please address to your local APV representative.

3. Mode of Operation

3Relief Valve

DELTA UF 3 (A) / UFR3 (A)

Operating Manual: Rev.5

DELTA UF3-UK5.qxp / 06.2008

The valve has been developed for use in the brewing and

beverage industries, in the dairy and food production as well as

in chemical and pharmaceutical applications.

It deals with an universally applicable valve design featuring high

mechanical reliability and simple servicing.

The UF3/UFR3 relief valve is applied to hold a product pressure or

to discharge a product quantity, as the process requires.

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 set value

adjusted falls short, the valve is closed by spring force.

The flow direction is always from A B.

Attention:

As defined by the Pressure Equipment Directive 97/23/EC,

the relief valve DELTA UF3/UFR3 is a "pressure accessory"

and not a "safet accessor ",

i.e. it must not be used as safety valve.

UF 31-A

* Seat lift actuator

The UF3 valve can be equipped with a seat lift actuator if required

for cleaning technical reasons.

(see chapter 5.)

* Valve position indication (fig. 4.1)

To indicate the valve position, proximity switches can be mounted

in the yoke area at (C).

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.

* Valve seat variants

Valve seats in flat and conical design, for special applications,

are available. Through the use of a valve seat with regulating

cone (D), the flow behaviour at low through put quantities is

improved and a “softer” valve closing is achieved.

This valve variant is called “UFR3“ (fig. 4.2).

* Housing shapes

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 (fig. 4.3).

* As a special version, the pressure relief valves are available

in aseptic design (with flat diaphragm or metal bellow).

- Deviations from the standard spare parts lists result. These

special drawings and spare parts lists will be supplied separately.

DELTA UF 3 (A) / UFR3 (A)

Operating Manual: Rev.5

DELTA UF3-UK5.qxp / 06.2008

Optimum cleaning is given if the seat lift actuator (E) drives

the valve seat into the position “on” during the cleaning process.

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 is driven into the position “off” by

spring force.

5. Cleaning

6. Installation

- 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.
