As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance Triple Offset Butterfly Valve. Engineered to meet the rigorous demands of global industrial markets, this valve is specifically designed for applications requiring zero leakage, reliable operation, and long-term durability. Our commitment to quality, backed by ISO9001 certification, ensures that every valve delivers exceptional performance in critical flow control systems across diverse industries.

This valve represents a significant advancement in isolation technology, combining robust construction with precise engineering. The triple offset design fundamentally eliminates wear and galling, providing a bubble-tight seal even after thousands of cycles. We understand the critical need for reliability in your operations, which is why our valves are manufactured to exacting standards, offering a solution that enhances system integrity and reduces total cost of ownership.

Core Features & Technical Advantages:

API 609 Certification: The valve is manufactured and tested in compliance with API 609 standards, ensuring it meets the performance requirements for critical service in oil, gas, petrochemical, and power generation applications. This certification provides assurance of quality and reliability.
Triple Offset Eccentric Design: This advanced geometry ensures that the disc only contacts the seat in the final moment of closure, virtually eliminating friction and wear during operation. The result is a longer service life and consistent sealing performance.
Premium Material Construction: Featuring a disc and shaft crafted from 316 Stainless Steel, the valve offers superior corrosion resistance, high strength, and excellent performance in a wide range of temperatures and media, including corrosive fluids.
Flexible Body Styles: Available in both Lug and Wafer styles to suit different piping system requirements. The Lug style allows for dead-end service and easier maintenance, while the Wafer style offers a compact, lightweight, and cost-effective solution for between-flange installation.
Bubble-Tight Shutoff: The conical seat and disc profile create a cam-action closure that produces a tight mechanical seal, achieving Class VI shut-off (zero leakage) according to relevant standards, which is crucial for safety and environmental protection.
Low Operating Torque: The frictionless operation due to the triple offset design requires lower actuation torque, allowing for the use of smaller, more economical actuators and reducing overall system energy requirements.

Choosing our API 609 Certified Triple Offset Valve means investing in a solution designed for longevity, safety, and efficiency. It is more than just a valve; it's a commitment to the reliability of your entire system. We invite you to contact us to discuss your specific application requirements, pressure ratings, sizes, and actuation needs. Let our expertise help you select the optimal valve configuration for your project.

Frequently Asked Questions (FAQ):

Q: What is the primary advantage of the triple offset design over a standard butterfly valve?
A: The triple offset design creates a cam-action closure where the disc does not rub against the seat until the final moment of sealing. This eliminates friction, reduces wear, ensures consistent bubble-tight shut-off over the valve's lifetime, and allows for reliable operation in higher pressure/temperature services.
Q: When should I choose a Lug style over a Wafer style for this valve?
A: Select the Lug style if your application requires dead-end service (where the valve is installed at the end of a line), if you need to support the weight of the piping on either side independently, or if you anticipate needing to remove downstream piping for maintenance without shutting down the entire line. The Wafer style is typically chosen for cost-effectiveness and compactness in standard between-flange installations.
Q: Is 316 Stainless Steel suitable for my specific corrosive media?
A: 316 Stainless Steel offers excellent general corrosion resistance, particularly against chlorides and other industrial chemicals. However, for highly specific or aggressive media, we recommend consulting with our technical team. We can provide material compatibility guidance and, if necessary, discuss alternative material options for the disc, shaft, and body.
Q: What does API 609 certification mean for my application?
A: API 609 is a standard from the American Petroleum Institute for "Butterfly Valves: Double Flange, Lug- and Wafer-Type." Certification means the valve is designed, manufactured, and tested to meet stringent requirements for dimensions, materials, pressure-temperature ratings, and performance (including seat leakage tests). It is widely recognized and often required in oil & gas, petrochemical, and other critical industries.
Q: Can this valve be automated, and what are my options?
A: Yes, this valve is designed for easy integration with various actuators. We can supply the valve as an operated unit with pneumatic (double-acting or spring-return), electric, or hydraulic actuators. The low operating torque of the triple offset design makes it highly efficient for automation.
Q: What pressure classes (ANSI) are typically available?
A: These valves are commonly supplied in ANSI Class 150 and Class 300 ratings. Higher pressure classes (e.g., Class 600, 900) are available upon request. The specific pressure rating will depend on the size and material configuration.
Q: Do you offer different seat materials for varying temperature ranges?
A: Yes. While the standard metal seat offers a wide temperature range, specialized seat materials (e.g., reinforced PTFE, other polymers, or different metal alloys) can be selected to optimize performance for extremely high, low, or cyclic temperature services. Please provide your service temperature details for a specific recommendation.
Q: What are the lead times for this product?
A: Lead times vary based on the valve size, pressure class, material specifications, and order quantity. We maintain strategic inventory for common configurations to ensure prompt delivery. Please contact our sales team with your requirements for an accurate delivery schedule.
