With regard to V..P47..
Locking the sliding sleeve, bayonet-ring, triggers the mechanical adaption of the
close- dimension. This affects a pre-tensioning for NC types (STA..) on the valve
stem resulting in a sealed valve. For NO types (STP..), the actuator stem will be
positioned above the valve spindle without pre-tension.
Lies in the range between 8.5…13.5 mm
