STAINLESS STEEL Wafer-Type Solenoid Metering Fine Butterfly Valve

The stainless steel wafer-type solenoid metering fine butterfly valve operates by using an electric solenoid to control the rotation of a small disc inside the valve body. When the solenoid is energized, it generates a magnetic force that moves the plunger, opening the disc to allow precise fluid flow. De-energizing the solenoid causes the plunger to return, closing the disc and stopping flow. The wafer-type design allows compact installation between flanges, while the fine disc and PTFE or metal seat provide accurate metering, low leakage, and smooth operation. This valve is ideal for dosing, chemical injection, or automated process control systems requiring precise flow regulation.

Valve parts

• Stainless steel body provides excellent corrosion resistance and long service life in fire water and harsh industrial environments.
• Aluminum lever offers lightweight, quick manual operation, enabling fast shut-off or opening during emergency fire protection situations.
• Lug style connection allows secure installation, supports end-of-line service, and ensures strong pipeline alignment and stability.
• Resilient seat design delivers reliable sealing performance, minimizing leakage under frequent operation and pressure fluctuations.
• Simple quarter-turn mechanism reduces maintenance requirements and ensures dependable, repeatable flow control performance.
  

The stainless steel DN300 eccentric rubber seat vacuum butterfly valve is widely used in industries requiring airtight flow control, such as vacuum packaging, pharmaceutical processing, and chemical manufacturing. For example, it can regulate air or gas flow in vacuum conveyors, control inert gas in chemical reactors, or maintain sterile conditions in pharmaceutical pipelines, ensuring reliable sealing and preventing contamination in sensitive processes.
