The traditional dyeing process is described as a black box, in which the amount of dye on the fabric is not known until the dyeing is completed. Advances in spectrophotometer and computation have enabled an indirect determination of the amount of dye on fabric during the dyeing process based on Beer’s law. The principles of a dye bath monitoring technology that allow the analysis and control of the dyeing process are introduced. This measurement technology can aid in troubleshooting root causes in shade reproducibility that can occur from variability in dye strength, the fabric, or the dyeing process.
A Digital flow Control Valve allows an increase in the output flow or pressure in the same proportion as the change in input. For instance, if the information is doubled, the output will increase by the same amount. This article will discuss the advantages and the applications of these valves.
What Are The Most Important Aspects of Using Digital Flow Control Valve?
Proportional flow control needle valves are suited to applications where the output pressure is expected to change – whether in steps or continuous. Stepped output pressure is maintained at a specific level until the pressure increases to another level. Constant output pressure occurs when pressure is constantly incremented at a certain amount. Pneumatic needle valves can be interconnected; for instance, the output can be utilized as an input for another. Many of them are programmable and come with onboard diagnostics, which makes them ideal for Industries 4.0 designs for systems. They’re reliable and economical (mainly controlled by air pilots) and provide quick responses and consistent control.
Use of Digital flow Control Valve in Dying System:
Many dyeing processes consist of the repetition of certain procedures or sequences of events that can be modeled and thus controlled. The mathematical methods of controlling different dyeing parameters are then explained. Specifically, pH measurement, the effect of various parameters on pH, and the development of pH control strategies are examined. The performance of different electric hydraulic flow control valves on the outcome of dyeing, using a pilot package dyeing machine, is also briefly investigated. The control of the dyeing process according to pre-set exhaustion and other profiles is also described. The precise control of temperature via steam is carried electronic flow control valve like Schubert & Salver’s sliding gate control valve. Often the Digital flow Control Valve is also used to control water for cooling after the dyeing process.
System Modeling: The Valvistor valve is classified as a two-stage Digital flow Control Valve. The poppet valve is the main stage, while the solenoid-operated proportional spool valve acts as the stage pilot. The poppet’s channel and the slots on the sides of the electric needle valve close the hydraulic feedback loop that controls the poppet’s displacement. The poppet’s displacement corresponds to the size of the orifice created by the slot and valve body. The valve body has an underlay inside the place so that the oil will be pumped into the upper chamber in the stage after the central orifice shuts.

Digital control flow value is the most important device in the mechanical industry of medicine & in other industries also. There are many types of Digital flow control valves. Like pinch valve, proportional flow control valve. Every valve has its own importance. But we have described a digital flow control valve in this article.
The main purpose of a digital flow control valve is to adjust and control the volume flow of ait within a pneumatic system. They are often used to adjust the speed of operation of an actuator. Might be, They should not be confused with pressure controllers or regulators.
What is a smart positioner in the control valve?
Smart valve positioners are digital valve controllers, microprocessor-based, current to pneumatic instruments with internal logic capability. They are specially designed to convert current signals to a pressure signals to operate a valve.

Reduce the water flow:
The digital flow control valve is also used to reduce the flow of water to reduce the rate of flow in a section of a pneumatic circuit, resulting in a slower actuator speed. Dissimilarly Needle Valve, this is the main point to known as Flow Control Valve regulates airflow in only one direction, which is allowing free flow in the opposite direction
