- The spot drilling jig has been designed to drill a 13 mm hole through a ½" ball valve into pressurized compressed air pipes, air ducts and funnels.
By means of a special drilling device a measuring site with 1/2" ball valve can be easily set up within a few minutes.
As an alternative to the welding of the 1/2” fitting also a spot drilling collar can be used.
Pressure range: up to 16 bar
Drill diameter: 13mm
Spot drilling collars
- For the later setting up of a measuring point for different measuring devices
- For steel pipes or pipes with diameters of DN 40 up to
- DN 200
If there is no measuring site with 1/2" ball valve present it can be set up by means of spot drilling collars. The spot drilling collar is imposed onto the pipe and tightened via thread rods. The enveloping rubber gasket is pressure-tight up to 16 bar. By means of the drilling jig it is possible to drill through the 1/2" ball valve into the existing pipe.
Important: Please indicate the exact outer diameter of the existing pipe when placing the order resp. please select the suitable spot drilling collar from the adjoining list.
