What Are Lined Globe Control Valves?

Definition and Purpose

Lined globe control valves are advanced industrial tools. They regulate fluid flow in pipelines. These valves have a protective inner coating. This coating is often made of PTFE or similar anti-corrosion materials. It shields against harsh chemicals and tough conditions. Their main goal is to ensure accurate flow control. They also provide durability and resist corrosion. This makes them ideal for handling corrosive or abrasive substances. Industries rely on these valves for safe and efficient operations.

Key Components

A lined globe control valve consists of several vital parts:

• Valve Body: The outer shell. It houses internal components. It ensures structural strength.
• Internal Lining: A protective layer inside. Made from materials like PTFE. It guards against chemical damage.
• Stem and Actuator: The stem connects to an actuator or handwheel. This allows the operator to adjust the valve disc. It enables precise flow control.
• Valve Disc: A movable part. It regulates or stops fluid flow by interacting with the seat.
• Seat: A fixed component. It forms a seal with the disc. This prevents leaks when the valve is closed.

Globe valves are linear motion valves. They serve both on-off and throttling functions. Their short travel ensures precise control. This makes them versatile in various industrial settings. They are widely used for their reliability and efficiency.

Advantages

Factors to Consider When Choosing a Valve

Media Compatibility

Choosing a valve requires checking its compatibility with the process media. The internal lining, often PTFE, resists corrosion. It protects against chemical damage. This makes them suitable for acids, alkalis, or solvents. The lining material must match the media’s chemical properties. This prevents wear. It ensures long-term reliability.

Globe valves are torque-seated. They handle on-off and throttling tasks. Their precise flow control is vital where specific rates matter. The lining reduces wear from abrasive materials. This boosts performance in tough settings. Proper material selection enhances valve efficiency. It ensures safe and consistent operation.

Temperature and Pressure Needs

Operating temperature and pressure are crucial. Valves must withstand extreme conditions. They should maintain structure and function. The lining material must remain effective under thermal and mechanical stress. This ensures reliable performance.

Globe valves come in Class 150-1500 configurations. This range suits various industrial needs. Matching the valve’s pressure rating to the system is key. This prevents failures or safety risks. Proper selection ensures operational stability. It supports long-term durability.

Maintenance and Costs

Maintenance and operational costs are important. These valves are durable due to strong builds and linings. They require less frequent repairs. This lowers costs over time. They are cost-effective for reliable flow control.

Their design allows easy disassembly and cleaning. This simplifies maintenance. These improve efficiency. They reduce downtime during servicing. This enhances overall productivity. It minimizes operational disruptions.
