mounted and tested, fully ready for field installation. Two valves are
mounted on a 125 lb. cast iron tee; one valve complete with power
actuator, the second valve controlled through connecting slave
linkage. The valves are linked so that as one valve opens, the other
valve closes. The tee arrangement desired should be specified by
indicating the appropriate tee position (1 through 7 below), and the
placement of both the power valve and slave valve respectively as
