Hawlinger pipe drilling saddles with lower PE-X fusion ends are to be used for welding into electrofusion saddles +GF+ type ELGEF® Plus .
In combination with fittings, the upper female thread outlets are used to connect service lines.
All Hawle pipe drilling saddles type Hawlinger are provided with a shut-off blade of stainless steel driven via slotted link gear as shut-off device. The shut-off blade is moved in a housing at low wear in horizontal direction against fixed metal stops.
To open or close the outlet area only one half revolution (180°) is required. In combination with a drilling device (e.g. HAWLOMAT, model no. 830-00) the shut-off system permits the easy under pressure drilling of the main line.
