What are the key features of a Lined Plug Valve? Essential for Harsh Chemical Handling

Lined Plug Valves are specialized valves designed for handling solid fluids and harsh chemical environments. Their key features include robust construction with PTFE lining for chemical resistance, full-port design for optimal flow, and durable operation under high temperatures and pressures. These valves offer reliable performance with low torque operation and easy maintenance, making them ideal for industrial applications requiring frequent operation and minimal downtime.

Key Points Explained:

1. Material and Lining Construction

   • PTFE (Polytetrafluoroethylene) lining is used throughout the valve body and wetted parts, providing exceptional chemical resistance and non-stick properties.
   • The lining protects internal metal components from corrosion and abrasion, ensuring longevity and reducing maintenance needs.
   • FEP/PFA uniform lining is also used in some models to prevent liner blowout or collapse under pressure.

2. Design Features

   • Full-port design allows for optimal throughput, minimizing pressure drop and ensuring smooth fluid flow.
   • Two-piece, bolted body construction provides durability and ease of maintenance.
   • Integral ball stem unit and low torque manual lever operation make the valve easy to operate, even in high-pressure environments.

3. Operational Characteristics

   • Quarter-turn operation with positive stops ensures quick and reliable opening and closing.
   • The design accommodates partial open positions for metered flow control, offering versatility in various applications.
   • Panel mount capability is available for all models, making them suitable for integration into complex systems.

4. Performance Specifications

   • Sizes range from DN15 to DN300, catering to a wide variety of industrial needs.
   • Can withstand temperatures up to 200 degrees Celsius, making them suitable for high-temperature environments.
   • Pressure ratings of Ansi 150 and Ansi 300 ensure reliable performance under high-pressure conditions.

5. Maintenance and Durability

   • Easily replaceable seats and liners reduce downtime and maintenance costs.
   • Leak-proof designs enhance safety and operational efficiency.
   • The robust construction and high-quality materials ensure long service life even in demanding applications.

6. Applications

   • Ideal for handling solid fluids and aggressive chemicals in industries such as chemical processing, pharmaceuticals, and water treatment.
   • Suitable for high ambient temperature environments, providing reliable performance in extreme conditions.
