Circuit Balancing Valves
(Model T/S-1710)
PRESSURE/TEMPERATURE RATING
The Figure 1710 is suitable for 290 psi pressure rating. It must be installed in a piping system,
where the normal pressure does not exceed this rating. The maximum temperature is restricted
to 250°F.
SITING
Conventionally, valves and commissioning sets are installed in horizontal pipework. This is,
however, not a constraint and they may be mounted in vertical or inclined pipework, inverted or
rotated to clear walls, ceilings and other restrictions.
INSTALLATION
Unpack the valve and check that the bores are clean and free from foreign material. Also check
that the adjoining pipework is clean and free from debris and burrs.
Confirm that the pipe threading length is correct to avoid excessive penetration of the pipe into
the valve which may otherwise cause damage.
Sealing compound may be used but excessive use of hemp type materials should be avoided
which increases the thread interference and may cause overstressing of the body ends.
