As a dedicated manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents its high-performance Triple Eccentric Hard Seal Butterfly Valve, engineered specifically for demanding shipboard steam line applications. With an annual export value reaching up to US$1.5 million and a strong presence across global markets from North America to Southeast Asia, we understand the critical need for reliability in marine environments. Our valve is designed to deliver exceptional sealing performance and durability under pressures up to 10 MPa, providing a robust solution for shipbuilders and marine engineers seeking to enhance system integrity and operational safety.
Core Product Features & Technical Advantages:
- Advanced Triple Eccentric Design: This design principle ensures a cam-action during operation, where the disc only contacts the seat at the final moment of closure. This eliminates friction and wear during 90% of the travel, significantly extending the service life of the seal and reducing maintenance requirements.
- Metal-to-Metal Hard Seal: The valve employs a precision-machined metal seat and disc, creating a bubble-tight seal suitable for high-temperature, high-pressure steam applications. This hard seal construction offers superior resistance to erosion, corrosion, and thermal cycling compared to soft-sealed alternatives.
- High-Pressure Capability: Engineered and tested to perform reliably in steam systems with pressures up to 10 MPa, making it an ideal choice for main and auxiliary steam lines, boiler outlets, and other critical high-pressure points onboard vessels.
- Versatile Actuation Options: To suit various automation and control needs, the valve is compatible with multiple actuation methods. This flexibility allows for seamless integration into modern ship control systems.
- Robust Construction & Materials: The valve body and critical components are typically fabricated from high-grade carbon steel or stainless steel (A216 WCB, CF8, CF8M, etc.), selected for their strength and corrosion resistance in marine atmospheres.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a triple eccentric design over a standard butterfly valve for steam service?
A: The triple eccentric design creates a camming action that separates the disc from the seat during most of its rotation, eliminating sliding friction. This is crucial for steam applications as it prevents rapid seat wear and galling, ensuring long-lasting, leak-tight shut-off even after numerous cycles. -
Q: Can this valve be used with other media besides steam?
A: Absolutely. While optimized for high-pressure steam, the hard seal and robust construction make it suitable for a range of demanding services, including hot oil, gas, corrosive chemicals, and other high-temperature fluids where a reliable seal is required. -
Q: What types of end connections do you offer?
A: We provide various standard connections to match your piping system, including wafer, lug, and flanged types (ANSI, JIS, DIN, etc.). The specific connection can be customized based on your project specifications. -
Q: Is the valve suitable for both isolation and throttling control?
A: This valve is primarily designed for isolation (on/off) service due to its metal-seated, bubble-tight shut-off characteristic. While it can be used for moderate throttling, for precise flow control, a different valve type might be recommended. -
Q: How do I select the right actuator for automated operation?
A: Actuator selection depends on required torque, available power source (air/electric), control signal, and fail-safe requirements. We can assist in specifying the appropriate pneumatic or electric actuator package based on your valve size and operating conditions. -
Q: What is your lead time for standard orders?
A: Lead times vary based on valve size, material, and configuration. Generally, for standard specifications, production can be completed within a reasonable timeframe. We provide accurate lead time estimates upon receipt of your detailed inquiry. -
Q: Do you provide documentation like test reports and certificates?
A: Yes, as an ISO9001 certified manufacturer, we can provide necessary documentation, including material test reports, pressure test certificates, and dimensional inspection reports, upon request. -
Q: Can you customize the valve for specific pressure or temperature outside the standard range?
A: Yes, our engineering team can work with you to develop customized solutions for special pressure ratings, extreme temperatures, or unique material requirements to meet the specific needs of your marine application.
