Hawle valve saddles are to be used for lateral installation on DCI, steel, and AC pipes DN 65 - DN 500. Adaptation to the main pipe is effected via holding strap and saddle gasket (model no. 309-00, 310-00 or model no. 311-00, 311-01, 311-02, 311-03) of the appropriate nominal width.
In combination with a drilling device (e.g. Hawle drilling device HAWLOMAT, model no. 830-00) the shut-off system permits the easy under pressure drilling of the main line.
In combination with fittings, the lateral female thread outlet is used to connect service lines after drilling.
