7�3 Installation of accessories for manual pressurization of the pilot pressure
Installation of the pneumatic coupling (Pos� 4) and control - / bleeding valve (Pos� 3)
Î
Screw the pilot pressure port 'P2' of the control - / bleeding valve (Pos. 3) pres-
sure-tight to the pilot pressure port 'P1' of the WEH
®
Connector.
For the tightening torque please refer to the table on Page 16.
Î
Screw the pilot pressure port ‘P1’ of the pneumatic coupling (Pos. 4) pressure-tight
onto the connection port of the pilot pressure line.
For the tightening torque please refer to the table on Page 16.
Installation of the hand slide valve (Pos� 6) and, if necessary, the thread extension (Pos� 5)
Î
Screw the pilot pressure port 'P2' of the hand slide valve (Pos. 6) pressure-tight to
the pilot pressure port 'P1' of the WEH
®
Connector.
For the tightening torque please refer to the table on Page 16.
Note: For small body sizes where, for reasons of space, the hand slide valve can not
be screwed directly into the pilot pressure port 'P1' of the WEH
®
Connector, a thread
extension (Pos. 5) can be screwed in between. First screw the thread extension to
the hand slide valve, then screw the extension into the connector.
Î
Screw the pilot pressure port ‘P1’ of the hand slide valve (Pos. 6) pressure-tight onto
the connection port of the pilot pressure line.
For the tightening torque please refer to the table on Page 16.
Installation of the Elbow 90°
Î
Screw the pilot pressure port 'P2' of the elbow pressure-tight to the pilot pressure
port 'P1' of the WEH
®
Connector.
For the tightening torque, please refer to the table on Page 16.
Î
Screw the pilot pressure port ‘P1’ of the elbow pressure-tight onto the connection
port of the pilot pressure line, the hand slide valve (Pos. 6) or the control - / bleeding
valve (Pos. 3). For the tightening torque please refer to the table on Page16.
7�4 Checking the connection for leak tightness
Î
Connect the connector to a closed test piece.
Î
Slowly apply the operating pressure to the connector and media line.
Caution: The test piece must be closed.
Î
Check the connector, the connection to the media line, the connection to the pilot
pressure ports and the connection to the test piece for leak tightness.
Attention: Do not use a leak detection spray that contains ammonia, since this could
cause corrosion of the connector.
