2 actuators and Terminology of components

2.1 Basic terms 2.1.1 Actuator [terminal control element] finalcontrolingelement Control system forward path directly change the manipulated variable instrument, the actuator and control agencies. 2.1.2 Control valve [valve] controlvalve Process control system with the power to change the operating fluid flow means, by the implementing agencies and valves, actuators in accordance with a control signal Changing the position of the valve closure member. 2.1.3 Solenoid solenoidvalve Energizing the coil excitation generated electromagnetic force to drive the spool valve switch. 2.1.4 Self-regulating valve self-operatedregulator [self-actuatedregulator] No external power source, relying on controlled fluid energy operations and to achieve self-regulating valve controlled variable. 2.1.5 Adjustment mechanism correctingelement Driven by the implementing agency, directly changing mechanism manipulated variables. 2.1.6 Valve valve Embedded control fluid flow with a pressure closure member seal housing assembly. 2.1.7 Actuator actuator The switching control signal to the corresponding action to control the position of the valve means within the closure member or other regulatory agencies. Signal or power source can be Pneumatic, any combination of electric, hydraulic, or the three. 2.1.8 Pneumatic actuator pneumaticactuator The use of pressurized gas as a power source of the actuator. 2.1.9 Electric actuator electricactuator The use of electric power source as the executing agency.
