InstallatIon and MaIntenance InstructIons

4.1.1 Sampling valve for sampling into bottles

1a. SAPRO sampling valve wafer type face-to-face dimension (Din/AnSi).

1b. SAPRO sampling valve flanged face-to-face dimension (Din or AnSi).

2. Dead man's lever.

3. Safety pin.

4. grub screw for flow control.

5. lock nut for fixing the grub screw.

6. bottle adaptor, standard thread to iSO gl32 or gl45, customized threads are possible.

7. Claw for fixing the bottle adaptor.

8. tapped vent hole of the bottle adaptor, standard g ¼".

9. Sampling bottle, borosilicate glass or PfA.

10. Padlock*, to prevent unauthorized opening of the valve.

* Padlock is not included in the delivery package

4.1.2 Bottle adaptor and sample bottle

- the Ptfe bottle adaptor (item 6) is screwed into the valve body and seals directly on the valve

seat with a Perfluor O-ring.

- the claw (item 7) secures the bottle adaptor against turning.

- the sample bottle (item 9) consists mostly of borosilicate glass with a round thread iSO gl45 or

iSO gl32 (Din168); bottles made of PfA are also available. bottle sizes: 50 - 1000 ml.

4.2 installation position

4.2.1 Installing sampling valve for sampling into bottles

the sampling valve for sampling into bottles can only be installed in such a way that the bottle

stands vertically.

for installation in a pipeline running vertically, an angle adaptor must be used (available as an

accessory).

4.3 sealing

the sealing of the sampling valve at the bottle adaptor is assured by the soft seat seal; at the

operating element (dead man's lever), a Ptfe sealing ring or a metal bellows is used.

the soft seat seal can be removed with a special tool and replaced (the pipeline must be

depressurized and drained!); in the event that the Ptfe sealing ring or the bellows start to leak,

the valve must be removed from the pipeline and sent in to the manufacturer. leakage past the

sealing ring or the bellows can be safely inspected via the leakage test hole on the upper neck of

the valve, and therefore it is recommended that the yellow plastic screwed plug fitted for shipping

is removed, and replaced, if possible, by screwing in a sensor. never seal the tapped hole with a

steel screwed plug!
