1.3 ELECTRONIC CONTROL VALVE CXT-E
Each Control Valve is comprised of three major sections; the Valve Body, Linkage Assembly
and the Valve Actuator. The Control Valves are available in sizes ranging from 1 inch to 4
inches. An identical Actuator Assembly is used with each size Valve Body. The Linkage
Assembly used with each size Valve Body is identical, except for minor differences in the Shaft
Adapter stroke of the mechanical linkage. Figure 1-4 shows the basic dimensions for each size
AERCO Control Valve CXT-E.
It should be noted that the Control Valves used for steam flow are identical to those used for hot
(boiler) water flow.
