Pneumatic Plug Valve

Key Specifications:

• Widely used in industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power and industry
• Nominal pressure: class 150 to 900lb
• PN: 1.0 to 16.0
• Working temperature: -29 to 550°C
• Has reasonable structure, reliable sealing, excellent performance and nice appearance
• According to various conditions, 3 ways, 4 ways plug valve can be designed into multiple media flowing forms (example L type or T type) or all kinds of material (example iron, cast steel and stainless steel ) or sealing type (example metal to metal, sleeve and lubricated type)
• Materials of parts and sizes of flanges can be reasonably configured according actual operating condition of requirements of customers, so as to meet various needs of engineering

Key Features:

1. Pneumatic Actuation:

   • Operated by a pneumatic actuator, which uses compressed air to automate the valve's opening and closing.

   • Provides fast and precise control, making it ideal for applications requiring frequent operation.

2. Quarter-Turn Operation:

   • The plug rotates 90 degrees to open or close the valve, allowing for quick and efficient flow control.

   • Suitable for both on/off and throttling applications.

3. Plug Design:

   • Features a cylindrical or conical plug with a through-hole that aligns with the flow path in the open position.

   • The plug can be lubricated or non-lubricated, depending on the design and application.

4. Materials:

   • Constructed from durable materials such as stainless steel, carbon steel, or alloys, depending on the application and fluid compatibility.

   • Sealing surfaces are often made from PTFE or elastomers for enhanced performance.

5. Applications:

   • Commonly used in oil and gas pipelines, chemical processing, water treatment, food and beverage, and pharmaceutical industries.

   • Suitable for handling liquids, gases, and slurries in high-pressure and high-temperature environments.

6. Advantages:

   • Provides reliable and automated flow control with minimal pressure drop.

   • Durable and long-lasting in harsh operating conditions.

   • Easy to integrate into automated systems.

   • Available in various sizes, pressure ratings, and configurations.
