Scope
GB/T 26815-2011 is the English-translated version of 工业自动化仪表术语 执行器术语.
GB/T 26815-2011 fixes the terms and definitions used for the actuators of industrial process control systems.
Clause 1 states that it applies to the terms and definitions of control valves, solenoid valves, self-regulating valves and other actuators that handle process fluid in industrial production process control, and that it is intended for use in developing actuator product standards, preparing documents, compiling teaching materials and books, and translating literature.
The standard has four clauses: Scope; actuators and Terminology of components; Functional and technical specifications of terms; and calculation and application of the term.
Clauses 2 and 3 are divided the same way, into basic terms, valve, pneumatic actuator, actuator, solenoid valve and self-regulating valve, with clause 2 adding a subclause for annex and other items, while clause 4 covers valve sizing, valve noise calculations and application.
The entries printed at the start of 2.1 are the actuator [terminal control element], the control valve [valve], the solenoid, the self-regulating valve, the adjustment mechanism, the valve, the actuator, the pneumatic actuator and the electric actuator.
The foreword states that words placed within square brackets are interchangeable terms. The document ends with an index, a pinyin index and an English equivalents index. It was issued on 2011-07-29 and has applied since 2011-12-01.

Foreword
The standard word square brackets [] within the interchangeable terms. The standard proposed by China Machinery Industry Federation.
1 Scope
This standard specifies the terms and definitions Industrial process control system to perform.
This standard applies to industrial production process control of process fluid control valves, solenoid valves, valves and other actuators term product Self-regulating And definitions.
The main criteria for the development of the implementation of standard products, preparation of documents, preparation of teaching materials and books and translation of documents, etc. to use.
2 Actuators and Terminology of components
2.1 Basic terms
2.1.1 Actuator [terminal control element]
Control system forward path directly change the manipulated variable instrument, the actuator and control agencies.
2.1.2 Control valve [valve]
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
Energizing the coil excitation generated electromagnetic force to drive the spool valve switch.
2.1.4 Self-regulating valve
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
Embedded control fluid flow with a pressure closure member seal housing assembly.
2.1.7 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
The use of pressurized gas as a power source of the actuator.
2.1.9 Electric actuator
The use of electric power source as the executing agency.
