The drain plug is used to drain remaining media from the ball valve.

De-pressurize the ball valve by turning the ball at 90° before removing drain and ventilation plug.
Danger!
Care must be taken when hazardous materials are involved!
Risk of explosion, fire and acid burn!
Place an appropriate vessel underneath the ball valve before opening the valve. The drain and ventilation
plug can easily be loosened and removed.
Damage can occur if it is not treated correctly (Figure 0105-00-001).
Drain and Ventilation Safety Plug
The safety plug is a special-purpose design to prevent the drain and ventilation plug from accidentally being
lost. In addition, it allows the drain and ventilation plugs to be closed immediately if the ball valve is still
accidentally pressurized (Figure 0105-00-002).
Installation
The complete safety plug is screwed into position using a chemical agent, such as Loctite.
Warning!
The plug may only be opened but not unscrewed by force (Figure 0105-00-003).
Warning!
Keep away from the outlet! Risk of injury!
Warning!
The medium is ejected sideways (Figure 0105-00-003)!
