Introduction
Scope of the Manual
This manual covers instructions for installation and
maintenance of Types P650, P163A, and P164A
cable actuators.
Description
Type P650 – Primary cable control for remote operation
of all NPS 1-1/4, 2, and 3 (DN 32, 50, and 80) size Fisher
internal valves. Assembly includes two fusible links,
a return spring, a 20-foot (6,1-meter) cable, two cable
clamps, a connector, and a machine screw.
Types P163A and P164A – Auxiliary remote release
assemblies that permit closing the internal valve from a
point other than at the primary cable control (Type P650).
Identical except for cable length, the Type P163A is 25 feet
(7,6 meters) and the Type P164A is 50 feet (15 meters).
Both can be installed through mounting brackets up to
3/8-inch (9,5 mm) thick. Also included are casing and
inner cable clamps.

Operation
There are three notches on the Type P650 control to
give a travel of 4, 5, or 6-inches (102, 127, or 152 mm).
All NPS 1-1/4 (DN 32) size Fisher internal valves require
the Type P650 be set in the first notch (4-inch (102 mm)
travel), and all NPS 2 and 3 (DN 50 and 80) size valves
require the Type P650 be set in the third notch (6-inch
(152 mm) travel) to assure adequate valve operating
lever travel. To open the internal valve, pull the
Type P650 handle to the correct notch. To close the
valve, hold the handle and push in on the release knob.
In emergencies, the release knob on the Type P650 can
be pushed to close the valve, but this procedure is not
recommended for everyday usage. The internal valve
can be closed from the auxiliary remote release points
by pulling the Type P163A or P164A tee handle. After
the auxiliary release has been operated and the internal
valve has closed, push the Type P163A or P164A
tee handle to its original position to reset the latching
mechanism of the Type P650.
Fusible elements at the internal valve, primary cable control,
and auxiliary remote release provide thermal release.
