Saf-T-Vise STV-XH1 7
Installation
Prior to installing the STV-XH1, ensure that the sealing surfaces are cleaned and free of debris . Then, place the
appropriate seal or ring joint on the mating flange .
With the coupon holder rod inserted through the body, place the STV-XH1 up against the mating flange . Install the
flange bolts, tightening them down in a star pattern .
For the Aceco flange version (STV-XH1-TF44), it is recommended to use the indicated 12-Point flange head cap screws
as these are the only standard screws with a head diameter small enough to not interfere with the lower body .
The API flange version (STV-XH1-TF3KH44) can accommodate hex bolts without interference issues . Insertion and
retraction of the rod under pressure requires use of the retractor tool, the STV-T4-XH1 . Information on initial setup can
be found in the Saf-T-Vise STV-T Series Insertion Tools manual .
Operation
This tool is designed to work with the STV-T4-XH1 retraction tool . Details on the insertion and retraction operation of
this product can be found in the IOM for the STV-T series .
