Direct Acting Solenoid Valves: Principles of Operation and Applications
- صمام ديلكو
صمام الملف اللولبي المباشر التشغيل is widely used in pharmaceuticals, laboratory equipment and industrial automation. In this article, DELCO Valve introduces this type of valve in terms of its operating principle and application scenarios.
What is a Direct Acting Solenoid Valve?
A Direct Acting Solenoid Valve is a solenoid valve in which the spool is actuated directly by a solenoid coil. It is not dependent on system pressure. The spool is able to open or close at zero pressure, making it particularly suitable for fluid control in low flow, low pressure, or vacuum environments.
Working Principle of Direct-Acting Solenoid Valve
The working principle of direct-acting solenoid valve is relatively simple. When energized, the solenoid coil generates electromagnetic force, directly suction spool, so that the spool is shifted. And in the event of power failure, the electromagnetic force disappears, the valve spool by spring reset to restore the original state.
Application Scenarios
- Pharmaceutical industry: In pharmaceutical liquid distribution, Direct Acting Solenoid Valve can realize small dosage and high precision flow control.
- Laboratory equipment: for fluid regulation in analytical instruments to ensure stable sample delivery.
- Industrial automation: In lubrication systems or pneumatic equipment, Direct Acting Solenoid Valves are used for precise control of small flows of gases or liquids.
- Food & Beverage: Used in beverage dispensers and small filling equipment to ensure a consistent amount of fill each time.
Selection Guide
- Choose material according to media: stainless steel for corrosive liquids, plastic for water or gas.
- Confirm the voltage requirement: choose the working voltage of the solenoid valve according to the requirement of the equipment (e.g. 12V DC or 220V AC).
- Consider the size of the diameter and flow: according to the pipeline size and flow requirements to choose the appropriate valve diameter.
Installation and Maintenance Recommendations
- Correct installation: Ensure that the direction of the valve is the same as the flow direction of the pipeline, and avoid reverse installation to affect the performance.
- Regular cleaning: Clean the inside of the valve body to prevent impurities from clogging the spool.
- Check the solenoid coil: check the working condition of the coil regularly to prevent overheating damage.
الخاتمة
The Direct Acting Solenoid Valve is characterized by sensitivity and high accuracy, making it ideal for use in small flow control applications.
