EF Threaded Air Saddles

Black EF Saddle VAM RG TL / PN16 / SDR11

This Friatec valve tapping saddle includes an integrated Gunmetal threaded adaptor, typically used for attaching DN50 air valves via a threaded ball valve for isolation. Installation can be either during construction or post-construction when the pipeline is under normal operating pressure.  If operational, the connection can be made 'live' using under pressure tapping equipment.  This prevents the main having to be shut down during the installation process.

The VAM RG must be installed using a top-loading clamping unit, to apply and maintain force on the saddle during the fusing and cooling period.  The Top Loading unit is available for rental.

Pressure test of the saddle after fusion is recommended, before drilling the tapping hole into the main pipe.

Saddle fittings allow for very compact Air Valve connections where space above the crown of the pipe is limited, they also allow the air valves to be installed at a later date after the high points in the pipeline have been established.  Click here for an example of its post-construction installation at Hong Kong International Airport. The VAM RG TL can fit onto a wide range of pipe sizes from dn250 to dn560.

NOTE: The pipe surface must be prepared in accordance with the general installation instructions using a mechanical saddle peeler, 90% Isopropyl alcohol wipes and we recommend using the Friamat fusion control unit to achieve correct preheating and logging the full range of weld data available.
