2�0 Installation
2�1 General
2�1�1 Unpack valve carefully to avoid damage to valve,
accessories, or tubing.
2�1�2 Record all valve and accessory serial plate data
for future reference. Always provide serial and model
numbers when ordering spare parts.
2�2 Pipeline Mounting
Do not remove button head screw (9) and
washer (10) during installation� The function
of these parts is to hold the retainer (3) and
seal ring (8) in place and should be removed
only when the valve is to be disassembled for
maintenance (Figure 2)�
A. Before installing the valve in the line, clean pipe and
valve of all foreign materials such as welding chips,
scale, oil, grease or dirt. Gasket surfaces must be
thoroughly cleaned to ensure leak free joints.
B. Install valve in a horizontal or vertical line with the flow
tending to push the seal ring (8) against the ball (2) as
indicated by the flow arrow cast into the body. It is
recommended that if adjacent walls and piping permit,
the valve be oriented such that the ball opens upward.
This is especially important when handling slurries. See
Figure 1 for actuator mounting positions and for flow
direction and Table 5 for line flange bolting lengths.
Note: Flange bolt lengths are non-standard on inlet and
standard on outlet side.
C. Tighten bolting evenly and in crisscross fashion so that
the retainer (3) held in place by the line flange will bear
evenly against the seal ring (8).
D. The linkage of the 36005 V-Max valve has been
properly adjusted at the factory and requires no further
adjustment.
E. Where insulation of the valve body is required, do not
insulate the valve bonnet. See Figure 17.
2�3 Air Piping
2�3�1 Air piping must be adequately sized to provide the
regulated supply pressure specified on the nameplate. As
a general guideline, use 1/4" O.D. tubing or equivalent for
all air lines. If supply air line exceeds 25 feet in length, use
3/8" O.D. tubing.
2�3�2 The actuator is furnished with a 1/4" NPT instrument
air port on the upper case.
Before proceeding with changing actuator
position, air action or valve maintenance,
isolate valve, vent process pressure and shut
off air supply and signal air lines or electrical
lines to unit� It is recommended that the
valve be removed from the pipeline prior to
maintenance work� Keep hands and tools away
from the segmental ball, particularly when
disconnecting the actuator stem from shaft
arm as ball may rotate freely to its lowest
position
For each valve action (air to open/air to close) the
actuator may be positioned to either side of the pipe.
Actuator position is usually determined by adjacent
piping, obstacles of various types or air piping
arrangements. To reposition the actuator and/or bracket
follow the disassembly and reassembly instructions
below.
Note: Actuator positioning should be performed
prior to installing the valve in the pipeline. To change
actuator position and/or valve action refer to Figure 1
for desired position.
A. Remove valve from process line after closing isolating
valves and disconnecting all pneumatic tubing and
electrical wiring.
B. If valve is equipped with a handwheel (Figure 4)
disengage handwheel and remove retaining clips (63),
clevis pin (66) and pivot pins (72); remove entire hand-
wheel assembly from bracket (62).
C. Remove pivot pin retaining clips (40), pivot pin (39) and
spacer rings (69). Remove actuator hex nuts (75) and
washers (76). Remove actuator.
Note: Spacer rings apply only on handwheel option.
D. Remove shaft cover (42) and screw (43). Loosen lever
cap screw (33). Remove packing flange stud nuts (24),
bracket mounting stud nuts (24) and washers (18).
Loosen ball plug indicator arm (35).
E. If necessary, scribe a witness line on the lever (32)
in relation to the slot on the end of the shaft (5).
Note: Standard lever has arrows stamped into it for
alignment. For handwheel lever use slot for alignment.
F. Slide bracket (31) away from body until it clears bracket
and packing flange studs (26 and 25), allowing lever
(32) lever arm (64) and indicator arm (35) to be removed
from shaft. Total removal of the bracket is not required.
