Pay special attention to the instructions below so that severe personal injury and/or damagetothevalveareavoided.
2.3 Safety precautions
Installation:
Always read the technical data thoroughly (see chapter 6.1 Technical data) !
Always release compressed air after use
Never touch the clip assembly or the actuator piston rod if the actuator is supplied with compressed air
(see warning label)
Never stick your fingers through the valve ports if the actuator is supplied with compressed air
Operation:
Always read the technical data thoroughly (see chapter 6.1 Technical data)
Never touch the clip assembly or the actuator piston rod when the actuator is supplied with compressed
air (see warning label) !
Never pressurise air connections (AC1, AC3) simultaneously as both valve plugs can be lifted (can cause mixing)
Never touch the valve or the pipelines when processing hot liquids or when sterilizing.
Never throttle the leakage outlet
Never throttle the CIP outlet, if supplied
Always handle lye and acid with great care
Maintenance:
Always read the technical data thoroughly (see chapter 6.1 Technical data) !
Always fit the seals correctly
Always release compressed air after use
Always remove the CIP connections, if supplied, before service.
Never service the valve when it is hot
Never pressurise the valve/actuator when the valve is serviced
Never stick your fingers through the valve ports if the actuator is supplied with compressed air
Never touch the clip assembly or the actuator piston rod if the actuator is supplied with compressed air
(see warning label)
Always use Alfa Laval genuine spare parts. The warranty of Alfa Laval products is dependent on the use of
Alfa Laval genuine spare parts.
Transportation:
Always ensure that compressed air are released
Always ensure that all connections is disconnected before attempting to remove the valve from the installation
Always drain liquid out of valves before transportation
Always used predesigned lifting points if defined
Always ensure sufficient fixing of the valve during transportation - if specially designed packaging material is available, it
must be used

3.2 General information
Step 1
Always read the technical data carefully.
See section 6.1 Technical data
Always release compressed air after use.
Never touch the clip assembly or the actuator piston rod if the actuator is supplied with compressed air (see the warning label).
CAUTION
Fit the supplied warning label on the valve so that it is normally visible.
Alfa Laval cannot be held responsible for incorrect installation.
NOTE
Always install the valve vertically.
The leakage outlet must be turned downwards!
Step 2
Avoid stressing the valve as this can result in deformation of
the sealing area and misfunction of the valve (leakage or faulty
indication).
Pay special attention to:
-Vibrations.
- Thermal expansion of the tubes.
- Excessive welding.
- Overloading of the pipelines.
Risk of damage!

4Operation
The valve is designed for cleaning in place (CIP). CIP = Cleaning In Place.
Study the instructions carefully and pay special attention to the warnings!
NaOH = Caustic Soda. HNO3= Nitric acid.
Internal leakage in the valve is externally visible by means of the leakage outlet.
4.3 Recommended cleaning
Step 1
Never touch the valve or the pipelines when sterilising.
Caustic danger!
Always use rubber gloves! Always use protective
goggles!
Step 2
Never touch the valve or the pipelines when sterilising.
Burning danger!
TD 449-326
Step 3
Never throttle the leakage outlet.
Never throttle the CIP outlet, if supplied.
(Risk of mixing due to overpressure).

Step 4
Examples of cleaning agents:
Use clean water, free from chlorides.

Step 5
1. Avoid excessive concentration of the cleaning agent
=> Dose gradually!
2. Adjust the cleaning flow to the process.
Milk sterilization/viscous liquids
=> Increase the cleaning flow!
