3.2 Function
Valve is closed and opened pneumatically.
Closing: The valve mechanism moves towards the valve opening until it touches the
mechanical stop (4). Due to continued pressure, valve gate (1) and counter plate (2) spread
apart and effect leaktight closing.
Opening: Valve gate (1) and counter plate (2) are retracted and valve mechanism moves
back into the valve body.
