Instrument valve is a pipeline attachment, is now widely used to control the transport of fluids such as water, oil and gas fluid, much market users attention. So how does the instrument valve work and what is the working principle?
Instrument valve working principle
Instrument valve regulator with analog signals, also known as analog meter valve. It determines the controlled object parameters of the analog form of the measured value and the deviation of the given value, and according to a certain regulation law to produce analog output signal to promote the actuator to eliminate bias, the controlled parameters remain in the vicinity of a given value or change in accordance with a predetermined law. In automation instrumentation, instrumentation valves are often used to integrate instrumentation output signals in order to control the manufacturing process. The adjusted parameters include temperature, pressure, flow, level, composition and so on.
