What valve is the regulator? What does each model and specification stand for?
Control valve is also known as the control valve. In the whole process of industrial automation control industry, according to the control data signal to accept the adjustment of the control unit output, according to the actual operation of the driving force to change the total flow of material, working pressure, temperature, liquid level instrument and other technical parameters of the ultimate control components, today we take you to understand what the valve is? What does each model and specification stand for?

A, what is the valve regulating valve?
In the automatic control of intelligent processing plant, the regulating valve plays a very key role. The production and manufacturing of this kind of processing plant lies in the proper distribution and control of liquid substances. This control whether the exchange of kinetic energy, the reduction of working pressure or simple vessel feeding, must be some final control components to carry out.
Control valve alias control valve, according to the acceptance adjustment control unit output control data signal, rely on the driving force of the actual operation to change the total flow of liquid. Regulating valve is generally composed of actuators and valves. If according to its actuator application of the driving force, the valve can be divided into pneumatic control valve, electric control valve, liquid control valve control valve three, in addition, according to its functional and characteristic points, linear characteristics, such as percentage characteristics and hyperbolic characteristics of three.
Two, what does each model specification of regulating valve mean?
Globe valve Z, globe valve J, one-way throttle valve L, valve Q, disc valve D, pneumatic butterfly valve G, plug valve X, check valve and pump bottom valve H, valve A, pressure regulating valve Y, steam trap S, float ball valve F.
Valve model specification: “Z961Y-100I DN150″ this is also a detailed gate valve model, valve “DN150″ this is the valve specification for 150mm meaning, the front part: “Z961Y-100I” according to the above sequence diagram to sit, as shown below:
“Z” is unit 1; “9″ is 2 units; “6″ is 3 units; “1″ is 4 units; “Y” is 5 units; “100″ is 6 units; “I” is unit 7.
Valve specification consists of seven units, e.g. Z961y-100i DN150. *** units, indicating the type of valve, such as Z for globe valve, A for valve, D for disc valve. Unit 2, indicating driveline methods, e.g. 9 indicates electric, 6 indicates pneumatic, and 7 indicates hydraulic-controlled valves. The third unit, indicating the connection mode, such as 6 indicates electric welding, 4 indicates flange. The fourth unit, indicating the structural form, such as 1 for single gate valve. Unit 5, indicate the raw material number of the protruding and lining, for example, Y indicates carbide cutting tools, X indicates plastics.
