Frequently Asked Questions (FAQ)
-
Q: What does "API 609" mean for this butterfly valve?
A: API 609 is an American Petroleum Institute standard specifically for butterfly valves. It defines requirements for design, materials, pressure-temperature ratings, testing, and documentation. Compliance ensures the valve is suitable for bi-directional shut-off and throttling services in demanding industrial applications like power plants. -
Q: How is the "Zero Leakage Guarantee" validated?
A: We validate this guarantee through rigorous factory acceptance testing, typically following standards like API 598 or FCI 70-2. Each valve undergoes a seat leakage test under specified pressures to ensure bubble-tight shut-off, with test certificates provided upon request. -
Q: Can this valve handle both steam and feedwater service?
A: Yes, it is engineered for both. However, material selection is crucial. For high-temperature steam, metal-seated trims (e.g., stainless steel, Inconel) are recommended. For feedwater, options include both metal and resilient seats, depending on temperature and chemical treatment. Our engineers can help specify the optimal trim. -
Q: What are the available actuation options?
A: We offer a range: manual gear operators for simple on/off isolation, and electric or pneumatic actuators for automated control. Actuators can be sized and configured to meet specific torque, speed, and control signal requirements (e.g., 4-20mA, on/off). -
Q: What is the typical delivery lead time?
A: Lead time varies based on size, material, pressure class, and actuation package. Standard configurations typically have shorter lead times. We recommend contacting our sales team with your specific needs for an accurate schedule. Our multiple shipment ports facilitate efficient logistics. -
Q: Do you provide customizations for non-standard applications?
A: Absolutely. We can customize dimensions, materials, pressure ratings, end connections, and actuator interfaces to meet unique project specifications. Please provide your detailed requirements for a tailored solution. -
Q: What after-sales support do you offer?
A: We provide comprehensive technical documentation, including dimensional drawings, material certifications, and test reports. Operational and maintenance manuals are also supplied. Support is available for installation guidance and spare parts inquiries. -
Q: Are your valves suitable for replacement in existing power plant systems?
A: Yes, a key advantage of API 609 valves is their standardization. Our valves are designed to be direct replacements for many existing butterfly valves in power plant service, minimizing retrofit engineering. Providing the existing valve's details allows us to confirm compatibility.
