INSTALLATION - MAINTENANCE MANUAL
RF15 and RF30 Series
150 and 300 Lb. Flanged One piece Ball Valves
DESIGN
Thedesignfeaturesofthisvalveincludea onepiececonstruction
body which results in simplified maintenance and trouble free
operation. These valves feature a “free floating” ball. The ball
is not fixed, but is free to move with the line pressure. As a
result of this feature, these valves are capable of tight shut-off
with flow in either direction or dead-ended, regardless of the
position of the valve in the line.
Thedownstreamseat,oppositethepressurizedsideofaclosed
valve, must carry the load exerted by the line pressure on the
ball, while the upstream seat is subject to little load or wear.
For this reason, it is sometimes possible to increase useful seat
life by turning the valve end-for-end in the pipeline.
1. USE
The valve should be maintained as part of a preventative
maintenance program and in accordance with Flow-Tek’s
recommended pressure, temperature and corrosion limits to
insure a long service life. During shipment, storage, and in
operation,thevalveshouldbefullyopenorfullyclosed (“open”
is preferred for shipping and storage). Do not use in throttling
service without investigating flow and pressure conditions.
WARNING: Beforeinstallingthisequipment,confirm
that it is suitable for the intended service.
The identifications tags describe the maximum allowable
service conditions for this product.
Besurethattheinstallationisprotectedbyappropriatepressure
control and safety devices to insure that acceptable limits are
not exceeded.
2. OPERATION:
Operation of the valve is done by turning the handle a 1/4
turn (90 degree turn). Clockwise to close, counter clockwise
to open.
A. VALVE OPEN POSITlON
The handle is parallel with the pipeline.
B. VALVE IN CLOSED POSITION
The handle is perpendicular to the pipeline.
Valves with actuators should be checked for actuator -valve
alignment. Misalignment will result in high operational torque
and damage to stem and seals.
3. STEM SEAL ADJUSTMENT
1. For 1”- 2”, if slight leakage is noted at stem, straighten
lock washer tab, tighten stem nut to flatten Bellville
Washers, back stem nut off 1/4 turn, secure lock washer
tab.
2. For sizes larger than 2”, simply tighten gland bolts
evenly until leak stops. Do not over tighten.
4. GENERAL INFORMATION FOR ON-SITE
INSTALLATION
The valve may be fitted in any position on the pipeline.
Before installing the valves, the pipes must be flushed clean of
dirt, burrs, and welding residues, or the seats and ball surface
will be damaged.
5. DISASSEMBLY AND CLEANING PROCEDURE
CAUTION: Line must be depressurized before
disassembly. Valve should be cycled to assure there
is no pressure is trapped in valve cavity. Ball valves
can trap pressurized media when closed. Flush line
with valve 1/2 open to remove hazardous media.
Valve should be cycled to assure there is no pressure
in the valve body cavity.
Warning:DONOTremovepacking glandoranyother
valve parts while line is under pressure!
1. If the valve has been used to control hazardous media,
it must be decontaminated before disassembly. It is
recommended that the following steps are taken for safe
removal and reassembly.

2. As shipped from the factory, valves contain a Silicone
based lubricant. This is for break-in and may be removed,
if it is objectionable for a particular application, by
disassembling and solvent washing.
Stem seal leakage may be corrected without disassembly
by tightening the packing gland nut until such leakage stops.
If the leakage continues or valve operating torque becomes
excessive, the seals are worn and replacement will be
necessary.

6. DISASSEMBLY
Stem seal leakage may be corrected without disassembly.
Tighten the packing gland nuts until leakage stops. If leakage
continues or valves operating torque becomes excessive, the
seals are worn and replacement will be necessary.
Warning: DO NOT remove packing gland or any
other valve parts while line is under pressure! Under
no circumstance! Line must be depressurized before
disassembly.
A. Remove valve from line and clamp in vise with handle
and removable body insert in an accessible position.
B. Put ball in the OPEN position. Insert spanner wrench
into slot in the retainer and rotate the counter-clockwise.
C. Remove body seal from body. Use caution to prevent
damage to metal parts; discard seal.
D. Turn handle to CLOSED position so that the stem tang
and ball slot are in line with the port opening. Lift or roll
ball out of insert end.
E. If stem seals are to be replaced, remove handle retainer
nut, stop plate and packing gland. Push stem into valve
cavity and remove from retainer end.
F. Remove seats from insert and body cavity, remove stem
seals.
7. VISUAL INSPECTION:
Clean and inspect metal parts. It is not necessary to replace
the hall and stem unless the seating surfaces have been
damaged by abrasion or corrosion. Replacement of all soft
parts whenever the valve is disassembled for reconditioning
is strongly recommended. This is the surest protection against
subsequent leakage after valve assembly. The replacement
parts can he ordered in kit form.
NOTE: The valve may be assembled and operated
dry where no lubricants are allowed in the system;
however, a light lubrication of mating parts will aid
in assembly and reduce initial operating torque.
Lubricantused must becompatible with theintended
line fluid.
8. ASSEMBLY:
1. Install one seat in the body cavity with the spherical
curvature facing the ball.
2. Install thrust washer on stem and slide the stem up
through the body. Install packing and packing gland
with packing gland bolt.
3. Install stop plate, handle and handle nut.
4. Turn the handle to the CLOSED position. Line up the ball
slot with the stem tang and slide the ball into position.
Open the valve to hold the ball in place.
5. Install the remaining seat in the insert with the spherical
curvature facing the ball. Install body gasket.
6. Carefully center the insert and press down until the
threads are engaged. Start the threads clockwise by
hand tightening with the tool used for removal. The end
cap should be tightened until the end cap is flush with the
flange face. The insert bottoms out in a metal to metal fit.
7. Cycle the valve slowly, with a gentle back and forth
motion, to build gradually to the full quarter turn. By
cycling slowly, the seat lips will assure a permanent seal
shape against the ball. A fast turning motion, at this point,
may cut the seats before they have a chance to form the
proper seal.
8. If a tester is available, pressure test valve prior to
reinstallation.

9. TEST AS FOLLOWS:
Test valve, if possible, prior to placing valve back into
line position. WARNING: If not properly secured,
the valve can separate from the pressure source,
resulting in possible injury. Always join the valve
to companion flanges of same pressure rating as
valve and secure with a full set of flange bolts.
1. Secure valve to a test future by means of a mating flange
with full bolting and a suitable gasket. Orient valve so
seat to be tested is facing up.
2. Introduce 50 to 100 psig air. Partially cycle the valve,
under pressure, and then slowly close to make sure
the cavity is pressurized (use hearing protection). Pour
water into the upper port to cover the ball and visually
check for bubbles. If bubbles appear, pour the water
out, cycle the valve several times and recheck. To check
for leakage in the other port, reverse the valve and
introduce air pressure to the port just checked.
3. Check the stem seal at this time by coating the gland
area with a soapy water solution. If leakage occurs,
tighten stem seal just until leakage stops.

protect the ball and seats.
3. Ball valves should remain in the original shipping
container and be placed on pallets of wood or other
suitable materials. End protectors should remain on the
valve ends to prevent the entrance of dirt, and removed
only at time of installation.
Long-Term Storage
Long-term storage is defined as storage of products and/
or equipment for periods longer than 3 months. Long-term
storage must be carried out in a controlled manner as
follows:
1. Valves must be stored in a closed, clean, and dry
environment.
2. Ball valves should be stored in the fully open position to
protect the ball and seats.
3. Ball valves should remain in the original shipping
container and be placed on pallets of wood or other
suitable materials. End protectors should remain on the
valve ends to prevent the entrance of dirt, and removed
only at time of installation.
4. Periodically, the valves should be checked to ensure the
above conditions are maintained.
