If supplied, remove the pneumatic valve head in the same way. 0 mm (M) 00 mm (W6, W8) Position vertically! Welding on a tank:. Weld the valve body horisontally on the tank.. Maintain the minimum clearance so that the valve head can be removed. Rotate clockwise! "/NW5 Position vertically! Welding on a tube:. Weld the valve body horisontally on the tube.. Maintain the minimum clearance so that the valve head can be removed.. Fit valve head (5) in valve body () and tighten firmly.. If supplied, fit the pneumatic valve head in the same way. 5 Open/close! 6 Air, max. bar Open/close! Pre-use check - Manual valve: Open and close the valve a few times to ensure that it operates smoothly. Pre-use check - Automatic valve:. Supply compressed air to the valve.. Open and close the valve a few times to ensure that it operates smoothly. Pay special attention to the warning!

8 Operation Study the instructions carefully and pay special attention to the warnings! The valve operation is either adjustable or nonadjustable and is carried out by means of different valve heads.. General operation - Always read the technical data thoroughly (see page ). - Always release compressed air after use (automatic valve). 7 CAUTION! We cannot be held responsible for incorrect operation. Burning danger! Never touch the valve body or the tank/ pipelines when sampling or sterilizing. Rotate! Burning danger! Pressurised! 5 Never touch the liquids from sampling or sterilization when they are discharged from the valve. Adjustable manual operation:. Release the key, if fitted.. Rotate the finger grip clockwise to carry out sampling. 6 Air, max. bar Activate! Non-adjustable on/off operation: Activate the lever to carry out sampling. Non-adjustable pneumatic operation: Supply compressed air to the valve to carry out sampling. Pay special attention to the warnings!

9 Operation Study the instructions carefully. Sterilize the valve with alcohol or steam after sampling. Alcohol: 70% alcohol.. Sampling/sterilization with alcohol 8. Close the lower hose connection of the valve.. Fill the valve with alcohol.. The valve is now ready for sampling.. Remove the rubber cap.. Let the valve drain. NOTE! If using a Steam Generator, the interior of the valve should be sterilized for approx. 0 seconds. Activate! Close the upper hose connection with the rubber cap. Open the valve to carry out sampling: - Rotate the finger grip on the adjustable valve clockwise. - Activate the lever on the on/off valve. - Supply compressed air to the pneumatic valve. 5 6 Activate! Carry out the sampling (see sampling accessories on page 0). Close the valve after sampling: - Rotate the finger grip on the adjustable valve anticlockwise. - Deactivate the lever on the on/off valve. - Release the air pressure on the pneumatic valve.

10 Operation Study the instructions carefully. Alcohol: 70% alcohol. Sampling and sterilization can be carried out by means of various accessories (see page 0).. Sampling/Sterilization with alcohol 7 Use a syringe! 8 Use a syringe! 9. Remove the cap.. Rinse with water or alcohol by using a syringe.. Sampling/sterilization with Steam Generator.
