At the inlet end thereof, the wear pipe (k) carries a counter nut (m).
The wash pipe valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the wash pipe valve.
An upper or jet valve allows switching between the squeeze and circulation positions without risk of closing the wash pipe valve.
The nozzle comprises a wear pipe (k) arranged in a supporting pipe (s) and comprising a nozzle tip (1) which by an external thread is screwed into an insert (e) at the outlet end of the nozzle housing (b).
An upper or jet valve allows switching between the squeeze and circulation positions without risk of closing the wash pipe valve.
