Siphon Valve​

Product Overview

As a professional fluid control device, the siphon valve leverages its unique siphon principle design to achieve efficient and stable fluid transmission and control.


Sizes: 1/2", 3/8"


Connection Method

Threaded connection (internal thread)


Product Features

  • Exceptional Corrosion Resistance: Made of PTFE material with outstanding chemical stability, it resists erosion from various strong acids, alkalis, organic solvents, and other chemicals, ensuring the valve remains undamaged by corrosion during long-term use.

  • Superior Sealing Performance: The PTFE material delivers excellent sealing properties. The valve’s sealing surfaces fit tightly together, effectively preventing medium leakage and ensuring stable operation of the fluid control system.

  • Efficient Siphon Principle: Utilizing the siphon effect, the valve generates a naturally formed negative pressure to draw liquid from a lower level to a higher level without requiring additional power sources, enabling energy-saving and efficient fluid transfer.

  • Automatic Start-Stop Function: Equipped with an automatic start-stop mechanism, the valve closes automatically when the liquid reaches a predetermined height, preventing backflow and ensuring system safety.

  • Strong Adaptability: The PTFE siphon valve is compatible with multiple media and operating environments, maintaining optimal performance in high-temperature, low-temperature, or high-pressure conditions.

  • Easy Installation: Designed with standardization in mind, the valve features a simple and quick installation process, reducing both user operational costs and time investment.



Application Scenarios

PTFE siphon valves are widely used in fluid control systems across the chemical, pharmaceutical, and environmental protection industries. In chemical production, they handle various corrosive liquids; in pharmaceutical manufacturing, they ensure the purity of drug production processes; and in environmental engineering, they are applied to sewage treatment and discharge.
