One of the most critical issues faced in fluid control systems is valve leakage, which can result in contamination, inefficiencies, and safety hazards. Plug valves address this concern through their unique sealing mechanisms. The plug, which rotates inside the valve body, forms a tight seal against the valve seat. This tight seal prevents leakage even under high-pressure conditions, ensuring the integrity of the system.

Valve Type

Rotary plug valve used for isolation or throttling in piping systems.

Flow Regulation Method

Plug rotates inside valve body to regulate or completely block fluid flow.

Differential Pressure Range

Operates efficiently within 0.2 to 16 bar differential pressure range.

Hydraulic Authority Recommendation

Minimum 30% hydraulic authority ensures precise flow control and valve responsiveness.

Valve Characteristic Curve

Available in linear or equal percentage flow characteristic options.

Product Description

The design of the plug valve also minimizes the contact surface between the plug and the seat, reducing the risk of wear and tear, and ensuring a consistent seal over time. Materials such as PTFE or elastomers are used in the sealing areas to provide additional resistance to chemical degradation, improving the valve’s reliability in harsh environments.

Test Point Configuration

Equipped with two test points for pressure monitoring upstream and downstream.

Maximum Allowable Flow Velocity

Supports flow velocities up to 5 m/s for liquids; 3 m/s for gases.

Leakage Class (per EN 12266-1)

Certified to Class A for bubble-tight shut-off with zero visible leakage.

Body Material Options

Offered in cast iron, ductile iron, stainless steel, carbon steel, and bronze.

Design Pressure Class

Available in pressure classes PN10 to PN40 for diverse industrial applications.

Thermal Expansion Compatibility

Materials selected to handle thermal expansion without affecting performance.

Installation Sensitivity

Low sensitivity allows flexible installation in vertical or horizontal positions.

Control Accuracy

Maintains ±5% accuracy under steady-state flow conditions for reliable control.

Position Repeatability

Achieves ±1% repeatability ensuring consistent performance during operation cycles.

Technical Advantages

In many industrial processes, valves are exposed to high-velocity flows, abrasive particles, and aggressive fluids. This creates significant wear on valve components, leading to decreased performance, frequent repairs, and system downtime. Plug valves are built to withstand these challenging conditions due to their solid construction and wear-resistant materials.

The plug itself is often constructed from high-strength materials such as hardened stainless steel or alloys designed to resist corrosion and abrasion. For applications involving slurries or high solids content, plug valves can be fitted with hard-faced plugs to further improve their resistance to wear. These features contribute to extended valve life and reduced maintenance needs, making plug valves suitable for heavy-duty industrial applications.

Power Generation

Used in steam and gas turbines for regulating flow in cooling and heating systems, enduring high thermal stresses.

Pharmaceutical Manufacturing

Provides contamination-free flow control for sterile environments, ensuring reliable sealing and ease of cleaning in production lines.

Food and Beverage

Controls fluid movement in processing lines, ensuring sanitary standards are met with easy maintenance and durable materials.

Pulp and Paper Industry

Regulates slurry and chemical flow in pulping and paper-making processes, maintaining efficiency and resistance to abrasive materials.

Mining & Mineral Processing

Handles slurries and abrasive fluids in mining operations, providing reliable shutoff and flow control under heavy-duty conditions.

Compact Design and Space Efficiency

Modern facilities often face space constraints that influence equipment selection. Plug valves are ideal for tight installation spaces due to their compact design. They operate efficiently in confined areas, ensuring performance remains unaffected, making them the preferred option for smaller or more complex piping systems.

The low profile allows these valves to fit seamlessly into systems where other valve types may be too bulky or cumbersome. This design enhances space utilization while maintaining high performance and reliability. Furthermore, the simple construction reduces the need for extra supports or accessories, streamlining installation and reducing costs.
