Leakageproof Shut-off
In mixproof valve M/2.0, the upper and the lower valve housing are each fitted with a
valve seat.The chamber between the valve disks is connected to the open environment
by an isolation outlet integrated into the lower valve spindle. Should seal damage occur,
leaking fluid flows safely into the open. Defective seals can thus easily be detected. The
penetration of leaking fluids from one pipe into the other is excluded under normal oper-
ating conditions.
Actuator Function
Actuator with spring closing function (Z). The valve is closed in the non-actuated posi-
tion.
Distinguishing feature with control top T.VIS on completed installation (SET-UP):
•
