1. General Terms
This instruction manual has to be read carefully and observed by
the competent operating and service personnel.
We have to point out that we will not accept any liability for
damage or malfunctions resulting from the non-compliance with
this instruction 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 for operating safety. You will nd it wherever the activities
described are bearing risks of personal injury.
- Depressurize the line and cleaning system before any maintenance
work.
- Risk of injury by sudden valve operation
- Observe Service Instructions to ensure safe maintenance ofthe
valve.
- Do not remove the lead seal (malfunction of valve and loss of
guarantee).
3. Intended Use / Mode of Operation
The component-tested SI2 safety valve is used in those plant
sections which have to be protected against excessive pressure.
In the beverage and food industry as well as in pharmaceutical
applications, the valve protects tanks and other containers against
inadmissible excess pressure.
The SI2 safety valve prevents exceeding of the allowed operating
pressure by more than 10 %.
If the adjusted response pressure after opening falls below max.
10% with gases and max. 20 % with liquids, the valve closes.
The ow direction is always from AB.
Arbitrary, constructive changes at the valve will inuence safety
as well as the intended functionality of the valve and are not
permissible.

4. Auxiliary Equipment
The valve can optionally be equipped with manual seat lift or seat lift
actuator.
Reconstruction can be undertaken during operation without greater
efforts.
-Seat lift actuator
The SI2 valve can be equipped with a seat lift actuator if necessary
for reasons of cleanability and / or remote function control.
(see chapter 5)
-Valve feedback
A proximity switch to signal the closed or open position of the
valve seat (ON/OFF) can be mounted on the seat lift actuator (C) if
required.
We recommend using one of our APV standard types.
Operating distance: 5 mm / diameter: 1 mm / length: 30 mm.
If the customer decides to use a valve feedback other than APV
type, we cannot take over any liability for a faultless function.
-Cleaning device
An adapter with an integrated cleaning nozzle (D) can be anged
below the valve.
5. Cleaning
Lifting of the valve seat during the cleaning process
Rinsing of the contact surface between seat seal and seat and
of the housing with the valve outlet port by the cleaning liquid is
possible.
Cleaning device below the valve seat
Through an adapter with spraying device the product-wetted part of
the valve to the valve seat can be cleaned

6. Installation
-Installation must be in vertical position.
For this tting position the valve has a component mark of the
Technical Supervisory Board and is tested and adjusted
accordingly.
- The standard housing is equipped with groove anges (FN1B - with
inspection certicate APZ 3.1). The appropriate mating anges
FG1B are available.
- The response pressure adjusted in our factory must not be changed
(lead seal protection).
- The free discharge at the outlet side must always be ensured. For a
possible discharge of the liquid, bends and short pipes of the same
dimensions may be tted.
