Product Description:
1. The core advantages of FESTO solenoid valve
Safety and sealing
The magnetic-insulating sleeve core design and non-dynamic sealing structure completely eliminate the risk of external leakage; internal leakage is effectively managed through precise control technology.
High-quality sealing materials and precision processes ensure reliable sealing in high-pressure and high-speed fluid environments.
Efficient response and convenient integration
The response time is as short as milliseconds (the direct-acting type is as fast as a few milliseconds), which is suitable for high-precision control scenarios.
Simple structure and low price, easy to connect to industrial control computers, and quickly build an automation system.
Environmental adaptability and reliability
Compatible with a variety of media such as gas, liquid, steam, etc., and corrosion-resistant materials are suitable for complex working conditions.
Stable operation under high temperature, high pressure, vacuum or negative pressure conditions (direct-acting type supports zero-pressure start).
Long-life design reduces maintenance frequency and downtime costs.
Flexible control capabilities
Three working principles are provided: direct-acting, step-by-step direct-acting, and pilot-operated, covering different pressure differences and flow requirements.
Optional normally open/normally closed models to meet the requirements of continuous opening or fast closing.
Advantages in medical and industrial scenarios
Medical equipment field: micron-level motion accuracy and easy-to-clean design meet hygiene standards (such as GMP certification).
Industrial automation: seamless integration of pneumatic/hydraulic systems to support high-intensity applications such as robots and packaging equipment.
II. Precautions for use
Installation requirements
Step-by-step direct-acting solenoid valves must be installed horizontally, otherwise they may cause abnormal movement due to gravity.
When connecting the pipeline, it is necessary to clean the pipeline impurities to avoid clogging the small holes of the valve body (especially pilot solenoid valves).
Medium and environment adaptation
The medium needs to be clean, and a filter should be installed when it contains particulate matter to prevent the valve core from getting stuck or the seal from wearing.
The working pressure/temperature must not exceed the valve calibration range to avoid seal failure or component deformation (such as the piston type pressure limit of 2.5MPa).
Electrical and maintenance points
Direct-acting solenoid valves are sensitive to power supply voltage fluctuations, and stable power supply must be ensured.
Regularly check the seals (such as rubber diaphragms) and spring conditions, and replace aging parts in time.
When powered on for the first time, manually half-open the valve to verify that the switch direction is consistent with the indicator disk.
Key factors for selection
Diameter limitation: Direct-acting type is suitable for small-diameter scenarios ≤25mm, and pilot-operated type is required for large-diameter scenarios.
Pressure difference conditions: The pilot-operated type requires a starting pressure difference between the inlet and outlet, otherwise it will not work properly.
Special working conditions: Direct-acting type is preferred in zero-pressure/vacuum environments, and piston-type structure is used in high-pressure scenarios.
Tip: Some self-acting regulating valves do not require external power supply, but rely on medium pressure drive, and pressure signal pipes must be reserved during design.
