Bray Flow-Tek Triad Series Installation & Maintenance Manual

DESIGN
The design features of this valve include a three piece construction,
allowing ease of maintenance without special tools. 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
regardless of the position of the valve in the line.
The downstream seat, opposite the pressurized side of a closed
valve, must carry the load exerted by the line pressure on the ball,
while the upstream seat is subject to little load or wear. Turning
the valve end-for-end in the pipeline will increase useful seat
life by dividing seat wear between the two seats.
1. USE:
The valve should be maintained as part of a preventative main-
tenance program and in accordance with Flow-Tek's recom-
mended pressure, temperature and corrosion limits to ensure a
long service life. During shipment, storage, and in operation, the
valve should be fully open or fully closed ("open" is preferred
for shipping and storage). Do not use in throttling service without
investigating flow and pressure conditions.
WARNING: Before installing this equipment, confirm
that it is suitable for the intended service. The identifi-
cations tags describe the maximum allowable service
conditions for this product. Be sure that the installa-
tion is protected by appropriate pressure control and
safety devices to ensure that acceptable limits are not
exceeded.
2. OPERATION:
Operation of the valve is done by turning the handle a
(90 degree turn). CW to close, CCW to open.
A. VALVE OPEN POSITION
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 valve stem and seals.

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 & CLEANING PROCEDURES:
CAUTION: Line must be depressurized before disas-
sembly. 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 1 ⁄ open to remove hazardous media.

WARNING: DO NOT remove packing gland or any
other valve parts while line is under pressure!
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.
If the valve has been used to control hazardous media, it must
be decontaminated before disassembly.
It is recommended that the following steps be taken for safe
removal and assembly.
As shipped from the factory, Valves contain silicone based lubri-
cant. This is for break-in and may be removed by disassembly and
solvent washing, if it is objectionable for a particular application.
6. DISASSEMBLY FOR STEM AND SEAL REMOVAL:
1. Remove flange connections and lift valve from line for
servicing.
