Product Description:
General Properties
Brand: ASCO, a world-renowned brand in the field of fluid control, known for its high-quality products and advanced technology.
Model: There are various models of ASCO pulse valves, each designed to meet specific application requirements. The model number usually indicates specific features and specifications of the valve.
Working Principle
Electromagnetic Actuation: ASCO pulse valves are typically solenoid-operated. When an electrical signal is applied to the solenoid coil, it generates a magnetic field that attracts a plunger or armature. This movement opens the valve, allowing the fluid (usually compressed air) to flow through. When the electrical signal is removed, the valve closes due to the force of a spring or other mechanical means.
Diaphragm-Type Structure: Many ASCO pulse valves use a diaphragm as the main moving part. The diaphragm separates the valve's internal chamber into two parts. When the solenoid is activated, the pressure difference across the diaphragm causes it to move, opening the valve port and enabling the passage of the medium. This design provides a reliable and efficient way to control the flow of fluid with a quick response.
Technical Specifications
Operating Pressure Range: ASCO pulse valves are designed to operate within a specific pressure range. This range can vary depending on the model, but generally, they can handle pressures from a few psi (pounds per square inch) to several hundred psi. For example, some models may have an operating pressure range of 20-150 psi, ensuring they can adapt to different system requirements.
Flow Rate: The flow rate of ASCO pulse valves is an important property. It is usually measured in terms of cubic feet per minute (CFM) or liters per minute (LPM). The flow rate indicates the amount of fluid that can pass through the valve in a given time. Higher-flow-rate valves are suitable for applications that require a large volume of fluid to be pulsed, such as in large-scale dust collection systems.
Response Time: ASCO pulse valves are known for their fast response times. The response time is the time it takes for the valve to open and close after receiving an electrical signal. Typically, these valves can have response times in the order of milliseconds, allowing for precise control of the fluid flow in applications where rapid pulsing is required.
Voltage and Current Requirements: The solenoid in the ASCO pulse valve requires a specific voltage and current to operate. Common voltage ratings include 12V DC, 24V DC, 110V AC, and 220V AC. The current consumption also varies depending on the valve model and the solenoid's characteristics. It is important to ensure that the power supply meets the valve's requirements to ensure proper operation.
Material and Construction
Body Material: The body of ASCO pulse valves is usually made of high-quality materials such as brass, stainless steel, or plastic. Brass is often used for its excellent corrosion resistance and mechanical strength, making it suitable for a wide range of applications. Stainless steel is preferred in harsh environments or when dealing with corrosive fluids, as it offers enhanced resistance to rust and chemical attack. Plastic-bodied valves are lightweight and cost-effective, and they are suitable for applications where the operating conditions are less demanding.
Diaphragm Material: The diaphragm in ASCO pulse valves is typically made of a flexible and durable material such as rubber or a synthetic elastomer. These materials can withstand repeated flexing and provide good sealing performance. The choice of diaphragm material depends on the application requirements, including the type of fluid being handled, the operating temperature, and the chemical compatibility.

Applications:
In dust collection systems, ASCO pulse valves play a vital role, particularly in bag-house filters. They are essential for periodically pulsing compressed air into the filter bags to dislodge accumulated dust, which then falls into a hopper. This proactive measure helps ensure the dust collection system's efficiency by preventing filter bag clogging.
For industries dealing with powder handling and conveying tasks like food processing, pharmaceuticals, and chemical processing, ASCO pulse valves are indispensable. These valves are utilized to manage the flow of powders or granular materials by pulsating the air supply to pneumatic conveyors or fluid-bed systems.
When it comes to industrial pneumatic systems, ASCO pulse valves find widespread application. They are employed in various industrial pneumatic systems to control the actuation of pneumatic cylinders, operate pneumatic tools, and regulate air flow in compressed air distribution systems.
