1. Close removed valve.

2. Unscrew machine screw (part 11) with holding disc (part 12) from lower fixture of rubber lining of hose diaphragm valve..

3. Then divide valve into two halves by loosening bolts and nuts (part 10). Remove lower part of
body (part 2) from upper part of body (part 1) to expose the rubber lining (part 3).

4. Unscrew rubber lining (part 3, 3 a and 3b) from pressure part (part 4) mounted to stem (part 7). To do this, bend the rubber lining back slightly in order to expose the pressure part (part 4) and make unscrewing/screwing possible.

5. The new rubber lining can now be inserted into valve in inverse sequence. Make sure the threads on the pressure part and on the stem are not worn!

6. Attention:
It is essential to apply the holding disc (part 12) when mounting the lower fixture of rubber lining!!

Observe the following points when mounting hose diaphragm valve into piping:

The lateral rubber packings must lay flush with the body flanges. Valve must therefore be almost closed prior to mounting.
Use pipe flanges as per PN 10 DIN/EN 1092-1 with sealing strip Form B, e.g. type 11. Do not fit smooth flanges!

Observe the maximum admissible working pressure:

DN 15 - DN 80 = 6 bar
DN 100= 5 bar
DN 125 - DN 200      = 3 bar

Refer to our mounting and operating instructions for valves (type sheet 1300.1300 and supplements) when installing the complete valve.
