Choosing an Automated Valve
Application Criteria
Evaluate the role played by the valve in the system, i.e., determining whether it is flow regulation, closing or opening, number of turns or more. Ensure that the correct type of valve matches the operational functions of the system.
Material Type
Check that the material used in making the valve is suitable for the fluid (i.e, liquid or gaseous) that will be in contact, while avoiding corrosion by these elements.
Operational Condition
Incorporate pressure, temperature, and velocity factors in selecting a valve that can perform its function in such an environment.
Type of Management
Evaluate whether an electrical, hydraulic, or pneumatic actuator is precise for the system in relation to the power availability and the control preference.

Choose valves that are long-lasting and require minimal maintenance so as to minimize cases of downtime and overcome the high costs incurred when a system breaks down.
These aspects will enable you to select an automation valve suitable for your system, guaranteeing efficient performance.
Factors to Consider in Valve Selection
When selecting a valve for a specific automatic system, it is essential to be aware of current trends as well as existing codes and standards. The list below helps you to refine your analysis and make the most out of the remaining factors:
1
Properties of the Working Medium
The classification of the fluid (whether it is composed of liquid, gas, or slurry) plays a vital role in determining the type of valves to use. For example, abrasive and corrosive fluids require more resistant, standard components, such as stainless steel valves or alloys like Hastelloy. Current industry statistics indicate that up to 70% of the time, corrosive fluids are handled with stainless steel valves due to their high corrosion resistance. Further dimensions that influence this factor are the viscosity and temperature of the liquid. For fluids with high viscosity, larger valve openings and special valve designs may be necessary.
2
Valve Sizes and Flow Rates
Verification of the valve size is essential to avoid any possible pressure drop or flow restriction. The flow coefficient, Cv, is one of the primary coefficients that reflect the valve’s capacity to pass flow. These days, even a high-performance valve design software from a simple valve manufacturer enjoys a set of quite accurate means by which it is possible to calculate the most efficient coefficient for the necessary application. According to research, oversizing can lead to an increase in energy consumption of up to 15%.
3
Material Retention
It has also been facilitated by the development of composite materials that substituted conventional materials in most types of valves more recently. Titanium-based, purpose-built valves are gaining popularity in offshore installations and chemical processes due to their superior corrosion resistance. Nevertheless, the cost analysis shows that the use of non-metallic recommended materials in this chapter involves at least a 20-30% increase compared to structures made of ordinary materials; however, possible savings may be achieved in the future for these facilities.
4
Valve Energy Efficiency and Actuation
These days, one of the significant improvements achieved in automation valves is the usage of the new generation of electric actuators, which require about 30 percent less energy than traditional pneumatic actuators. Due to the introduction of the mentioned intelligent technologies, these actuators provide real-time control and monitoring capabilities, improving the system’s efficiency and reducing the amount of energy used. According to industry surveys, businesses that employ efficient valve systems typically save at least $10,000 per year in their production processes.
5
Regulatory Compliance and Guidelines
In certain areas, regulations such as ISO 9001, API (American Petroleum Institute) standards, or ASME (American Society of Mechanical Engineers) standards assure the quality and fidelity of products. Adopting valving, which meets these standards, can help address the issue of non-compliance in industries such as oil and gas or pharmaceuticals, where performance and safety are of grave concern.
By utilizing such information and focusing on current market dynamics and trends, one can implement well-founded plans to enhance the effectiveness and profitability of automated systems. Never forget to seek advice from valve manufacturers or authorities in the field regarding the matters highlighted above to fine-tune your use of automation valves.
Common Types of Automated Valves
Each type of automation valve used is unique, as it is primarily designed for specific applications within an industrial setup. The following outlines the five types of automation valves that are used most frequently.
Ball Valves
A ball valve consists of a ball in a passage through which a fluid or gas is allowed to pass, and a valve body. When it comes to tight shut off uses they are efficient. These valves are tough and withstand high pressures and temperatures.
Butterfly Valves
The essential butterfly valves have a lightweight design and use a rotating metallic disc to control the flow of fluids. This is because they are inexpensive in mass production and large in diameter. They are useful for applications with limited space due to their compact size.
Globe Valves
Globe valves are primarily used for throttle control. A plug is moved inside the valve near the stationary seat. These types of valves are generally used for control of applications where precise flow restriction is needed.
Gate Valves
Flow control through gate valves is achieved by moving a gate up or down to either initiate or halt the flow of fluid. They are mainly used where there is very little head loss; therefore, they are best used for isolation purposes.
Diaphragm Valves
The diaphragm valves consist of a diaphragm and a seat that control the flow. These valves are very efficient for liquids or gases that are either corrosive or viscous. This is because their mechanism allows the liquid or gas not to contaminate the mechanical parts of the valve.
All of these valves do have merits, and their use is motivated by tolerance to shear, viscosity of the material, and whether the material is active at high or low temperatures and pressure, and other factors.
Understanding Valve Size and Specifications
As you need to understand the pipe closer sizing, you must first take into consideration the few factors, such as the diameter of the pipe, the pressure that the valve is rated for, as well as the flow characteristics of the system that entails such an automation valve use. The desired flow rate and whether the fitting size as the valve intended for will not result in any dope necking or flow disturbance are also considered. Moreover, I always check the material out of which the valve is made. I also evaluate whether the medium and environmental conditions, such as temperature and pressure, to which the valve shall be subjected, can be dealt with, without compromising the functionality of the valve or causing its premature failure.
