As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance industrial flow control solutions. Our API 609 Triple Eccentric Butterfly Valve with a robust cast steel body and flanged ends represents our commitment to engineering excellence for demanding applications. Designed to meet the stringent requirements of global markets, including North America, Europe, and Southeast Asia, this valve offers superior sealing reliability, extended service life, and exceptional performance under high-pressure and high-temperature conditions, providing a cost-effective and reliable solution for critical process lines.
The core of this valve's performance lies in its innovative triple eccentric design. This geometry ensures that the disc seal only contacts the seat at the final moment of closure, eliminating sliding friction and wear during operation. This principle translates into significant benefits for our clients:
- Bubble-Tight Shut-Off: Achieves reliable sealing even for challenging media, reducing leakage and process losses.
- Extended Service Life: Minimal wear on sealing surfaces leads to lower maintenance costs and longer intervals between servicing.
- Low Operating Torque: The design reduces the force required to operate the valve, allowing for smaller, more economical actuators.
- Bi-Directional Sealing: Provides effective sealing in both flow directions, enhancing system design flexibility.
Constructed with a cast steel body, this valve offers excellent mechanical strength and durability, suitable for a wide range of industrial environments. The flanged ends facilitate easy and secure installation into existing piping systems, conforming to international flange standards. The valve is engineered to perform reliably across the specified pressure classes from Class 150 to 600, making it a versatile choice for various system requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a triple eccentric design over a standard butterfly valve?
A: The triple eccentric design virtually eliminates wear by ensuring the disc only contacts the seat upon final closure, not during rotation. This results in a much longer service life, bubble-tight sealing, and consistent performance, especially in high-cycle or critical service applications. -
Q: Is this valve suitable for high-temperature applications?
A: Yes, the combination of a cast steel body and metal-seated triple eccentric design makes this valve suitable for elevated temperature services. The specific temperature range depends on the selected seat and seal materials, which can be customized. -
Q: Can you provide valves with different flange face types or standards?
A: Absolutely. We can supply valves with Raised Face (RF), Ring Type Joint (RTJ), or Flat Face (FF) flanges. They can be manufactured to match common international standards such as ASME B16.5, EN, JIS, etc., based on your specifications. -
Q: What types of actuators are compatible with this valve?
A: The valve is designed for easy integration with a wide range of actuators. We can provide or recommend pneumatic (double-acting or spring-return), hydraulic, or electric actuators from reputable brands to suit your automation and control requirements. -
Q: What is the typical delivery lead time for an order?
A: Lead times vary based on order quantity, size, pressure class, and customization. Standard configurations often have shorter lead times. We provide accurate delivery estimates upon receipt of your detailed inquiry and work efficiently to meet project schedules. -
Q: Do you offer material test certificates and documentation?
A: Yes, as an ISO9001 certified manufacturer, we can provide standard material test certificates (like 3.1 or 3.2 per EN 10204) and other relevant documentation (e.g., pressure test reports) with the shipment upon request. -
Q: How does the pressure class (150, 300, 600) affect valve selection?
A: The pressure class defines the maximum allowable pressure at a given temperature. Selecting the correct class is crucial for safety and performance. Our team can assist you in choosing the appropriate class (150, 300, 400, or 600) based on your system's operating conditions. -
Q: What industries commonly use this type of valve?
A: This high-performance valve is widely used in oil & gas, petrochemical, power generation (including thermal and nuclear), LNG terminals, shipbuilding, and other heavy industries where reliable isolation of pipelines is required under demanding conditions.
