Gauge Hatch with flange

Función y Descripción

PROTEGO® gauge hatches types PF/K, PF/TK, and PS/KF are used as lockable gauge nozzles which are only opened for gauging or sampling. Otherwise, they are tightly closed.

The gauge hatches PROTEGO® PF/K, PF/TK, and PS/KF mainly consist of housing, cover, and bracket. The housing is equipped with stainless steel gauge marks as standard.

In the pedal-operated version PROTEGO® PF/TK, the gauging nozzle pedal is connected to both the housing and the bracket.
