40mm
20mm
32mm
50mm

The SIV self inserting valve is designed for small volume under-pressure tapping.
It is screwed into a tapping saddle making sure that the feed nut is completely unscrewed from the gland bonnet allowing the cutter to be in its fully retracted position.
  SIV TO POLY FERRULE
Size
15x16mm
25x32mm
40x50mm
20x25mm
32x40mm
50x63mm

The SIV to poly ferrule is the same as above together with an integral PE fitting for direct connection to polyethylene pipe without the use of an adaptor.
It is supplied complete with wedging ring, nut and thimble for this purpose.
Both these ferrules are only available in 20 and 25mm sizes. For other sizes underpressure it is necessary to use the TPFNR range.
Engage a ratchet spanner on the square spindle top and rotate clockwise while screwing down the feed with another spanner. Care must be taken not to feed the cutter too fast otherwise the cutter will be damaged. Immediately the cutter pierces the pipe water her rotating the feed will close the unscrew the feed approx. 10 turns
