Solenoid
Solenoid valves are used to control fluid in everyday tasks and extreme operations alike. Solenoid valves consist of a solenoid (a small electromagnetic coil) and a movable plunger that seals and unseals the valve. When an electric current passes through the solenoid, it exerts force on the plunger and opens or closes the valve.
This design allows solenoid valves to be both highly responsive for accurate fluid or gas regulation and a fast response time vital for safety applications as well as operated remotely with a simple electrical switch. Given these advantages, it is easy to understand why solenoid valves are so popular when controlling flow in anything from simple air systems to high volume industrial applications.
Solenoid valves are available in a variety of sizes and types like automated, pneumatic, hydraulic or electric, and can be customized to meet the specific needs of the application.
For decades, ASCO solenoid valves have been the global industry standard for dependable, high performance solenoid valves. Now a part of automation solutions titan Emerson, ASCO produces over 50,000 premium fluid control valves and their solenoid valves are the crown jewels of their inventory.
Affectionately nicknamed ‘red hats’ due to the bright red cap on the top of the valve, ASCO Red Hat solenoid valves are made with sturdy materials and often available in two-way, three-way and even four-way configurations. ASCO solenoid valves are built for longevity and success in a vast array of industrial applications.
Popular fluid control uses for ASCO Red Hat valves include general service, air, hot water and steam, light oil, cryogenic, combustion, navy & marine and even nuclear operations. When success and failure depend on the performance of your valves, you need the best – you need ASCO.
Automated Solenoid Valves
Are a type of valve that uses an electromechanical solenoid to control the flow of fluids in a pipeline or system. These valves are designed to provide remote or automated control over fluid flow, making them well-suited for applications where precise and rapid on/off control is required. Automated solenoid valves consist of a coil of wire (solenoid) wound around a ferromagnetic core. When an electric current flows through the coil, it generates a magnetic field that attracts a movable armature or plunger within the solenoid.
The movement of the armature or plunger within the solenoid is used to control the valve’s opening and closing. When the solenoid is energized (electric current is applied), the armature is drawn into the solenoid, opening the valve. When the solenoid is de-energized (electric current is removed), a spring or other mechanism returns the armature to its original position, closing the valve.
It’s important to properly select the appropriate solenoid valve based on factors such as fluid compatibility, pressure requirements, flow rates, and the specific automation needs of the application. Automated solenoid valves offer reliable, quick, and remote control over fluid flow, contributing to increased efficiency and process automation in various industries.
Process control ball valves offer accurate throttling capabilities, making them suitable for applications where precise regulation of fluid flow is essential.
What makes process control ball valves different? The ball is typically equipped with a flow-controlling trim, such as a V-port or a segmented ball, to achieve more precise throttling.
Pneumatic Solenoid Valves
Are a type of solenoid valve that are specifically designed to control the flow of compressed air in pneumatic systems. Compressed air is a common power source in industrial automation, robotics, and various manufacturing processes, and pneumatic solenoid valves play a crucial role in regulating the flow of this compressed air to achieve precise and automated control. Like other solenoid valves, pneumatic solenoid valves use an electromechanical solenoid to control the valve’s opening and closing.
When the solenoid is energized (electric current is applied), the electromagnetic field generated pulls the valve’s internal components, typically a plunger or spool, to open the valve. When the solenoid is de-energized, a spring or other mechanism returns the internal components to their original position, closing the valve.
Pneumatic solenoid valves come in various configurations, including two-way (2/2) and three-way (3/2 or 5/2) valves. Two-way valves control the flow of air between two ports (open or closed), while three-way valves control the flow between three ports, allowing for more complex control configurations. These valves provide efficient and accurate control over the flow of compressed air, enabling automation and enhancing the functionality of pneumatic applications.
Hydraulic Solenoid Valves
Are a type of solenoid valve designed to control the flow of hydraulic fluid within hydraulic systems. Hydraulic systems use pressurized fluid to transmit power and control various components in industries such as manufacturing, construction, and automotive. Hydraulic solenoid valves play a vital role in regulating the flow of hydraulic fluid to achieve precise control and automation in these applications. They are also designed to withstand the pressures and conditions of hydraulic systems.
Hydraulic solenoid valves are available in various materials, such as steel, stainless steel, and other corrosion-resistant materials, to suit different hydraulic applications. It’s essential to choose and install hydraulic solenoid valves correctly to ensure optimal performance and reliable operation in hydraulic systems. These valves provide efficient and precise control over the flow of hydraulic fluid, enabling automation and enhancing the functionality of hydraulic applications.
Electric Solenoid Valves
Are a type of valve that use an electromechanical solenoid to control the flow of fluids (liquids or gasses) within a pipeline or system. These valves are operated electrically and are commonly used in various applications for automated control, remote operation, and precise flow management. Electric solenoid valves come in various configurations, including normally closed (NC) and normally open (NO) versions.
NC valves are closed by default and open when the solenoid is energized, while NO valves are open by default and close when the solenoid is energized. Proper selection, installation, and maintenance of electric solenoid valves are important to ensure their optimal performance and reliable operation in various applications. These valves provide convenient and precise control over fluid flow, enabling automation and enhancing the efficiency of numerous processes and systems.
