Engineered with a double-offset disc and advanced seat materials, high-performance butterfly valves deliver tight shutoff, higher pressure ratings, and reliable control in demanding industrial applications.
High-Performance Design — Built for Tougher Conditions
High-performance butterfly valves use a double-offset disc profile to reduce seat friction, improve cycle life, and maintain a reliable seal under higher pressures and temperatures.
PTFE, reinforced PTFE, and metal seat options expand chemical and thermal compatibility, making these valves well-suited for steam, hydrocarbons, high-temperature water, and aggressive process media.
Their engineered construction provides dependable shutoff and smooth operation across systems where resilient seated valves begin to reach their limits.
What Are High-Performance Butterfly Valves?
A high-performance butterfly valve uses a double-offset (eccentric) disc design and advanced seat materials to control flow under higher pressures, temperatures, and operating demands. The first offset shifts the disc from the stem centerline, while the second offset sets the disc away from the seat plane.
This geometry reduces friction during operation, allowing the disc to lift smoothly off the seat with minimal wear.
Why Choose High-Performance Butterfly Valves?
High-performance butterfly valves are built for applications where higher pressures, elevated temperatures, or more demanding operating conditions require a stronger, more durable solution. Their double-offset design minimizes seat wear and provides consistent, reliable sealing across a wider range of media.
- Higher pressure and temperature capability for steam, hydrocarbons, and industrial process fluids.
- Improved sealing performance with PTFE, reinforced PTFE, or metal seats designed for tougher service conditions.
- Lower operating torque compared to traditional metal-seated valve designs.
- Longer seat life due to reduced friction during operation.
- Enhanced control characteristics for throttling or modulating service.
Types of High-Performance Butterfly Valves
High-performance butterfly valves come in several configurations designed to meet the requirements of higher pressure, higher temperature, and more demanding industrial systems. Each style offers its own installation and performance advantages, helping contractors and plant operators match valve selection to their application needs.
Double-Offset Valves
The standard HPBV design, offering reduced seat friction, longer service life, and improved sealing for a wide range of industrial applications.
Fire-Safe High-Performance Valves
Include a metal backup seat that maintains shutoff capability after exposure to fire or extreme heat.
PTFE- or Reinforced-PTFE–Seated Valves
Provide excellent chemical resistance and smooth operation for corrosive or high-purity process media.
Metal-Seated High-Performance Valves
Withstand elevated temperatures, steam, and more abrasive or high-energy service conditions.
How to Choose the Right High-Performance Butterfly Valve
Selecting the right high-performance butterfly valve ensures reliable shutoff, long service life, and safe operation in demanding systems. Consider the following factors when selecting the right valve for your application:
Pressure Class and
Operating Conditions
High-performance butterfly valves are available in different pressure classes (typically ANSI Class 150 and 300). Matching the valve’s pressure rating to the system’s maximum pressure and temperature ensures safe, consistent performance without premature wear or seat failure.
Seat and Disc
Material Selection
PTFE, reinforced PTFE, and metal seats each offer different advantages depending on the fluid, temperature, and required shutoff. Selecting the appropriate seat and disc materials ensures better chemical compatibility, tighter sealing, and longer service life in harsh or high-temperature environments.
Application and
Media Compatibility
Whether managing steam, hydrocarbons, process water, or corrosive chemicals, ensuring compatibility between valve materials and process media is critical. Understanding the system’s fluid characteristics helps prevent corrosion, leakage, and performance loss over time.
How High-Performance Butterfly Valves Are Used
Engineered for tougher conditions and higher performance demands, high-performance butterfly valves are used anywhere reliable shutoff, elevated pressure ratings, or improved temperature tolerance are essential.
Chemical Processing
Provides accurate flow control and leak-tight isolation in corrosive or high-purity chemical lines where PTFE or reinforced seats prevent contamination and degradation.
Steam and High-Temperature Water Systems
Maintains sealing integrity and cycle life under elevated temperatures, making them dependable for steam distribution, condensate return, and high-pressure hot water loops.
Oil, Gas, and Hydrocarbon Service
Supports safe, reliable shutoff in fuel, vapor, and hydrocarbon transfer lines, especially in systems that require fire-safe construction or metal-seated durability.
Power Generation and Industrial Utilities
Handles cooling water, condensate, auxiliary steam, and other plant utility flows where higher pressures and continuous operation demand improved valve strength and longevity.
Pulp and Paper Processing
Controls process fluids, bleaching chemicals, and high-temperature flows in demanding paper mill environments where resilient seated valves don’t meet pressure or temperature requirements.
Marine and Offshore Systems
Delivers reliable operation in shipboard and offshore environments where space constraints, pressure fluctuations, and harsh conditions require high-performance sealing and corrosion-resistant materials.
Best Practices for Installing, Operating & Maintaining High Performance Butterfly Valves
Proper installation and upkeep help ensure long-lasting performance, tight sealing, and reliable operation across demanding applications.
Installation Tips
- Verify that pipeline alignment is correct to prevent unnecessary stress on the disc and seat.
- Ensure the disc can rotate fully without contacting internal piping or adjacent components.
- Use the manufacturer’s recommended bolt torque and follow proper flange gasket guidelines for a secure, even seal.
- Confirm valve orientation and flow direction when applicable, especially on fire-safe or specialized seat designs.
Operating Guidelines
- Cycle the valve slowly at startup to confirm smooth movement and proper disc clearance.
- Use appropriate actuation (manual, gear, pneumatic, or electric) based on line pressure and operating frequency.
- Avoid throttling in positions not recommended for high-performance valves to limit premature wear on the seat and disc.
Maintenance Considerations
- Inspect seals, seats, and disc edges periodically for signs of wear or buildup.
- Check actuator mounting hardware and linkage for proper alignment and tightness.
- Keep the valve clean and free from debris that could impede sealing or operation.
- Follow the manufacturer’s service intervals for seat or packing replacement to maintain peak performance.
