304 Stainless Steel Ball Valve is a fluid control device widely used in various liquid and gas pipeline systems. Owing to the 304 stainless steel material's excellent corrosion resistance, this type of ball valve can operate stably in harsh environments.
Structural Features
Ball Structure
The ball is the core component of a 304 stainless steel ball valve, typically ** forged or cast from 304 stainless steel** and precision-machined to ensure optimal sealing with the valve seat. The ball features a through-hole that aligns with the pipeline axis when rotated 90° (full open position) and becomes perpendicular to it when closed. This simple 90° switching mechanism enables quick and easy operation, allowing for rapid opening/closing.
Seat Design
The valve seat is usually made of PTFE (Polytetrafluoroethylene), PPL (Polyphenylene) or other high-performance polymer materials, offering superior sealing and wear resistance. The seat forms a sealing pair with the ball, and stem pressure ensures tight contact between them for reliable sealing. For example, in high-pressure, high-temperature, or media containing solid particles, high-quality seat materials effectively prevent leakage and extend valve life.
Stem Structure
The stem, connecting the ball to the actuation device, is typically made of 304 stainless steel with tempering treatment for enhanced strength and toughness. It uses key or pin connections to ensure precise ball rotation. Additionally, the stem often includes anti-blowout features to prevent ejection under abnormal internal pressure, ensuring operator safety.
