Description

Product Overview: PANS High-Performance Butterfly Valve

PANS High-Performance Butterfly Valve features triple or double eccentric design to minimize sealing face friction and extend valve life. Key features include:

1. RPTFE Seat Uses “RPTFE” type seat with excellent elasticity and long service life, compensating for sealing area changes due to pressure/temperature variations or wear.

2. Self-Lubricated Bushing Equipped with ultra-low friction coefficient self-lubricated bushing, reducing friction between stem and bushing for smooth operation.

3. Tangential Pin Connection Disc and stem are connected by a “Tangential Pin,” enhancing stem strength and connection reliability.

4. Floating Seat Design Unique floating seat design automatically adjusts according to upstream pressure, achieving ideal double-directional sealing and extending valve life.

5. Anti-Blowout Design Prevents stem blowout due to connection failure between disc and stem.

6. Standard Mounting Complies with ISO 5211 standard for easy connection with electric, pneumatic, and manual actuators.

7. High-Performance Sealing Meets ANSI/FC170-2 and MSS-SP61 standards, achieving bubble-tight sealing, surpassing Class Wl.

8. Easy Maintenance Parts are interchangeable, allowing on-site replacement of defects with general tools.

High Performance Butterfly Valve FAQs

1. What distinguishes a high performance butterfly valve from standard butterfly valves?

A high performance butterfly valve is designed for more demanding applications, featuring advanced sealing mechanisms (like double or triple offset designs) and robust materials that allow it to operate reliably under higher pressures, temperatures, and more corrosive conditions than conventional butterfly valves.

2. What are the primary benefits of investing in a high performance butterfly valve?

Investing in a high performance butterfly valve offers benefits such as superior sealing integrity (often achieving bubble-tight shut-off), extended service life due to reduced wear, lower maintenance costs, and enhanced operational safety and efficiency in critical processes.

3. In what industrial applications are high performance butterfly valves most commonly utilized?

High performance butterfly valves are widely utilized in industries such as oil and gas, petrochemicals, power generation, chemical processing, and HVAC. They are ideal for applications requiring precise flow control, reliable isolation, and handling of abrasive, corrosive, or high-temperature media.

4. Can high performance butterfly valves be used for throttling or control applications?

Yes, many high performance butterfly valves, especially those with double or triple offset designs, are excellent for throttling and control applications. Their precise disc movement and robust sealing allow for accurate flow regulation, making them a cost-effective alternative to globe valves in many control loops.

5. What material options are available for high performance butterfly valves to suit different media?

High performance butterfly valves are available in a wide range of materials, including carbon steel, stainless steel (304, 316, duplex), and various alloys (e.g., Hastelloy, Monel). Material selection is critical and depends on the specific media’s corrosiveness, temperature, and pressure to ensure optimal performance and longevity.

6. Do you offer OEM/ODM services?

As a specialized manufacturer, we can design and manufacture valves according to your specific technical requirements.
