3. Safety instructions
3.1 Field of application
The check valve is suitable for use as a reflux - check valve for gas and fluid in plants in the food and
beverage, in pharmaceutical, biotechnological and chemical industries.
ATTENTION
• To avoid danger and damage, the fitting must be used in accordance with the safety instructions and technical
data contained in the operating instructions.
3.2 General safety instructions
DANGER
• Dismantling the valve or valve assemblies from the plant can cause injuries from fluids or gases flowing out.
Dismantle the valve or valve assembly only when the plant has been rendered pressure-less and
free of liquid and gas.
3.3 General notes
NOTE
All data are in line with the current state of development. Subject to change as a result of technical
progress.
4. Function
4.1 Description of function
The valve open against spring power with flow pressure > X bar in flow direction “A“ (see Tab.).
The valve close added by spring power with flow pressure > 0,1 bar in flow direction “B“.
Flow pressure*
NOTE
A pressure from min 0,8 bar is necessary for a leakproof shut off in flow direction "B".
5. Installation informations
5.1 Installation instructions
Fitting position
Check valve be installed preferably vertically, with the flow direction from bottom to top.
5.2 Welding guidelines
Sealing elements integrated in weld components must generally be removed prior to welding. To prevent
damage, welding should be undertaken by certified personnel (EN287). Use the TIG (tungsten inert gas)
welding process.
NOTE
Impurities can cause damage to the seals.
Clean inside areas prior to assembly.

The maintenance intervals depend on the operating conditions "temperature, temperature-intervals,
medium, cleaning medium, pressure and opening frequency". We recommend replacing the seals every
1 years. The user, however should establish appropriate maintenance intervals according to the con dition
of the seals.
6.2 Cleaning
The cleaning of the valve takes place during the pipe cleaning.
