GFB DV+ TMS Diverter Valve (part T9301) - Manual (Page 3)

Spring Pre-Load - continued
The dv+ comes with two different methods of spring pre-load adjustment, depending on your
preference and how much space you have above the valve:
•
Grub screw/locknut – quick and easy
adjustment on applications where there is
enough room above the valve to
accommodate it
•
Fixed length screw with low-profile head for limited space applications – the dv+ comes with an
assortment of screws to achieve different spring pre-loads. The screws are:
o 6mm (installed as standard – this is the
softest spring pre-load)
o 8mm
o 10mm
o 12mm
The softest spring pre-load is achieved using the
6mm screw length (the dv+ is supplied with this
screw installed). To increase the spring pre-load,
remove the existing screw, taking care not to
drop the o-ring (spare o-rings are supplied just in
case). Install a longer screw with the o-ring on
the thread as shown.
