_
CCW. This manual ball valve is functionally designated
as V22.
b.
Visually inspect position of ball valve by looking through valve body (5) to ensure that the valve is open.
Ensure valve is open with valve handle (1) in the open position as shown in the top portion of
Figure 3--38.
c.
Remove hex head allen screw (2), attaching handle (1) to ball valve, BVHP--O8--SSS--1NG, body (5). Do
not adjust or remove tension screw (4) when removing handle (1) from valve body (5).
d.
Remove handle (1) and spacer (3) from ball valve body (5) to expose cam plate (6) and stop pin (7). As
supplied, and with handle removed, cam plate (6) is configured as shown in middle portion of
Figure 3--38 (right hand operation configuration).
e.
Lift cam plate (6) from ball valve body (5) and rotate cam plate (6) 90
_
CCW so pin (7) on ball valve body
(5), with respect to cam plate, is positioned as shown on lower portion of Figure 3--38 for left hand
operation.
f.
Install spacer (3) and handle (1) on ball valve (now configured for left--hand operation).
g.
Install hex head allen screw (2) and tighten to secure handle (1) on valve body (5).
