Overflow valves (418, 618/619, 617/417, 608/609, 610) can be installed in any
position. The function of the valves is guaranteed in every position.
During assembly always make sure not to apply any force when fastening the
connecting thread and not to screw it in too far, as this could otherwise damage the
seat of the valve. Do not allow sealing material such as hemp or Teflon to penetrate
into the valve.

The valves can be delivered with a set pressure and sealed by the factory or without set
pressure with the desired range of adjustment. Valves which have been set and sealed
by the factory are marked with the set pressure. Before changing the set pressure the
seal has to be removed.
If valves are unsealed, the desired pressure can be set within the pressure range of the
spring.
Types 418, 604/605:
1. Unscrew capstan headed screw (1) and remove cap (2).
2. Release locknut (3).
3. Turn pressure screw (4). (In type 418 medium does not discharge via the spring
chamber even under operating conditions or with available counterpressure.)
Turn in clockwise direction to increase pressure, turn in counterclockwise direction
to reduce pressure.
4. Tighten locknut (3).
5. Mount cap (2) and fasten capstan headed screw (1).
Types 615/616:
1. Remove locking pin (1) and take off lever (2).
2. Unscrew cap nut (3).
3. Disengage bushing (4).
4. Loosen locking nut (7).
5. Turn pressure screw (6): Clockwise = increases pressure,
Anticlockwise = decreases pressure.
6. Tighten locking nut (7).
7. Engage bushing 4 in spindle (5).
8. Refit and tighten cap nut (3).
9. Fit locking pin in lever (2) and bushing (4).
Types 618/619:
1. Unscrew cap nut (7) and remove copper gasket (8).
2. Release locknut (3).
3. Turn pressure screw (4): Turn in clockwise direction to increase pressure, turn in
counterclockwise direction to reduce pressure.
4. Tighten locknut (3) again and mount copper gasket (8).
5. Screw on cap nut (7) and tighten.
