This **sanitary stainless steel manual welded butterfly-type ball valve** is designed for industrial applications where hygiene and durability are essential. The valve is manufactured using a **welded connection**, ensuring a secure and leak-proof seal. While standard welding is offered, **clamped or combined clamped/welded connections** can also be customized to meet specific requirements.
**Standard Design:** The valve follows the **ISO standard design**, ensuring compatibility with international piping systems. It is suitable for use in **food, beverage, pharmaceutical, and chemical processing systems**, where precise flow control is required.
**Working Principle:** This manually operated valve features a **90-degree rotary handle** that controls the ball inside the valve body. When the handle is turned, it rotates the ball, allowing the valve to open or close, regulating the flow of the medium within the system.
**Design Variants:** The NUOMENG ball valve series includes various types such as **welded, clamped, and threaded valves**, catering to different installation needs. Additionally, multiple standard series are available, including **DIN, 3A, SMS, ISO/IDF, BS/RJT, and ASME/BPE**, to suit diverse industry requirements.
**Key Components:** A typical ball valve consists of a handle, a ball with a through-hole, the valve body, the central spindle, and a shaft seal to prevent leakage.
**Material Specifications:**
- **Stainless Steel Parts:** 304 and 316L grades for high strength and corrosion resistance.
- **Seals:** Options include VMQ (vinyl methyl silicone), FPM (fluorocarbon), EPDM (ethylene propylene diene monomer), and PTFE (polytetrafluoroethylene) for different chemical environments.
