As a leading manufacturer with a strong presence in the global valve market, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our specialized API 609 Butterfly Valve with Fire Safe Design. Engineered specifically for the demanding environments of offshore marine piping systems, this valve combines robust construction with critical safety features to ensure reliable flow control and personnel protection. Our years of expertise since 2016 are distilled into this product, offering a dependable solution for oil & gas, petrochemical, and marine applications where performance under extreme conditions is non-negotiable. We understand the challenges of offshore operations, and our valve is designed to meet them head-on.

This valve is not just a component; it's a safeguard for your critical infrastructure. Its core value lies in providing a secure shut-off during fire events, preventing catastrophic failure, and maintaining system integrity when it matters most. Manufactured under our ISO9001-certified quality management system and exported worldwide from major Chinese ports, this valve represents a commitment to quality, safety, and global supply chain reliability that our partners across North America, Europe, Asia, and beyond have come to trust.

Key Product Features & Technical Advantages:

API 609 Compliant Design: Manufactured in strict accordance with API Standard 609 for butterfly valves, ensuring dimensional interchangeability, design integrity, and performance suitable for critical service applications.
Certified Fire Safe Performance: Features a fire-safe design tested to standards like API 607/6FA. In the event of a fire, the metal secondary seat provides a secondary seal, preventing leakage and containing the hazard.
Corrosion-Resistant Construction: Available in a range of materials including Carbon Steel, Stainless Steel (304/316), and Duplex Steel to withstand harsh offshore environments, including saltwater spray and corrosive process fluids.
Bidirectional Sealing: Engineered for reliable sealing in both flow directions, a crucial feature for complex marine piping systems where flow direction may change.
Low Torque Operation: The optimized disc and seat design ensures low operating torque, reducing wear on actuators and allowing for smoother, more efficient manual or automated operation.
Extended Service Life: Utilizes high-performance seat materials like PTFE or reinforced PTFE for standard service, with optional metal seats for high-temperature or abrasive service, maximizing valve longevity.
Versatile Actuation Options: Can be fitted with lever, gear, electric, or pneumatic actuators to suit any level of automation and control requirement on the platform or vessel.
Compact & Lightweight: Compared to gate or globe valves, the butterfly design offers a significant space and weight saving, which is a critical advantage in space-constrained offshore installations.

Frequently Asked Questions (FAQ)

Q: What exactly does "API 609" mean for this butterfly valve?
A: API 609 is an American Petroleum Institute standard titled "Butterfly Valves: Double Flanged, Lug- and Wafer-Type." Compliance ensures the valve meets specific design, material, pressure-temperature rating, testing, and dimension requirements, making it suitable for critical hydrocarbon and process service.
Q: How does the fire-safe feature work in an actual fire?
A: The valve incorporates a primary soft seat (e.g., PTFE) and a secondary metal seat. In a fire, the primary seat may degrade, but the metal-to-metal contact between the disc edge and the secondary seat creates a seal, significantly reducing leakage and helping to isolate the fire.
Q: Can this valve be used for both on/off service and throttling control in marine systems?
A: While primarily designed for reliable on/off isolation, especially in fire-safe contexts, the characteristic flow curve of a butterfly valve allows it to be used for throttling. For precise control, pairing it with a suitable modulating actuator is recommended.
Q: What material combination do you recommend for seawater service?
A: For untreated seawater, we typically recommend a Duplex or Super Duplex stainless steel body with a nickel-plated or high-grade stainless steel disc. This offers excellent resistance to pitting and crevice corrosion.
Q: Is the fire-safe testing certification included, and to which standard?
A> Fire-safe testing can be performed to standards like API 607 (soft-seated valves) or API 6FA (general valve fire test). Test reports or certificates from independent laboratories are available upon request to validate the performance.
Q: What is the lead time for an order of these valves?
A: Lead time depends on size, material, actuation, and order quantity. Standard configurations typically have shorter lead times. We provide accurate delivery schedules with every quotation to help with your project planning.
Q: Do you offer valves with actuators as a complete package?
A: Yes, we can supply the valve as a complete package with electric, pneumatic, or hydraulic actuators, including mounting and setting. We work with reputable actuator brands or can use your specified brand.
Q: Are your valves suitable for sour service (H2S environments)?
A> Valves can be supplied with materials compliant with NACE MR0175/ISO 15156 standards for sour service. Please specify this requirement during inquiry so we can recommend the appropriate material grades and hardening treatments.
