Type P650 Cables are the primary cable control for remote operation of all 1-1/4, 2, and 3-inch Fisher internal valves. Assembly includes two fusible links, a return spring, a 20-foot / 6,1 m cable, two-cable clamps, a connector and a machine screw. The cable systems can also be used on stationary storage tanks at bulk plants and on in-line applications to increase safety during transfer operations.
