3. Line Bolting Material must comply with ANSI B16.34
and be compatible with the in tend ed service.
4. Tighten the line bolting evenly and in small in cre-
ments to avoid uneven load ing of the seal retainer
(3) and seal retainer gas ket (9). See Ta ble 3 for
minimum and max i mum line bolt ing torques.
CAUTION
Do not allow the body to “cock” between the fl anges.
Valve must be centered on the fl anges.
D. Body Installation:
The Ranger QCT body can be installed be tween
ANSI Class 150, 300 or 600 lb. RF or FF fl anges
or their ISO equivalent of PN20, 50 or 100. Socket
weld, weld neck or slip on companion fl anges
can be used. Face-to-face di men sions are per
ISA 75.08.02.
1. Install valve so the fl ow direction matches the
arrow on the valve body.
2. For fl angeless design alignment, special
boss es cast on the valve body contact the
line bolting and help center the valve in the
pipe line. See Table 2 for Line Bolting Di men-
sions.
CAUTION
DO NOT USE THE RANGER BODY ASSEMBLY AND
LINE BOLTING TO PULL FLANGE PIPE ENDS INTO
ALIGNMENT. Seal retainer may shift, dam ag ing the
seal retainer gasket allowing leakage between body
and seal retainer. Movement of seal retainer may
compromise the valve's ability to meet stated shut-off
leakage rates. Could also allow leak age between body
and fl ange pipe ends.
WARNING
Do not adjust temporary air supply pressure after cover
plate (20) has been removed. Valve contains parts which
could move during maintenance exposing hand and/or
fi ngers to a hazardous condition.
b. Pressurize the actuator to a level 2-3 psig
(0.1–0.2 Barg) above the upper pressure
lev el of the bench setting as stated on the
name plate (21); i.e. 5–15 psig (.34–1.03
Barg) range, set pressure at 17–18 psig
(1.17–1.24 Barg).
c. Remove machine screws (36) and cov er
plate (20).
d. Locate “C” washer and remove. Re tight en
upper jam nut (43) to lower jam nut (43).
Re place cov er plate (20) and ma chine
screws (36).
e. De pres sur ize the actuator and check
trav el indicator (16) for full plug travel.
Disconnect temporary air supply.
NOTE: Save slotted “C” washer for reuse
when reinstalling the valve back into the
pip ing.
