Frequently Asked Questions (FAQ)
Q1: What does "API 609" mean for this butterfly valve?
A1: API 609 is a standard published by the American Petroleum Institute for "Fire Test for Soft-Seated Quarter-Turn Valves." Valves conforming to this standard are designed and tested to provide a degree of fire safety, meaning they are expected to maintain some sealing capability even after exposure to fire. It is a common requirement in oil & gas, petrochemical, and other industries where fire safety is critical.
Q2: Can this valve be used for on/off service only, or also for flow regulation (throttling)?
A2: It can be used for both. The standard electric actuator can be specified for simple on/off operation. For modulating (throttling) control, you need to select a proportional control actuator that accepts a control signal (like 4-20mA) to precisely position the valve disc. Please specify your requirement when inquiring.
Q3: Is the IP65 rating sufficient for outdoor installation?
A3: Yes, an IP65 rating means the actuator enclosure is "dust tight" and protected against water jets from any direction. This makes it highly suitable for most outdoor applications where it may be exposed to rain, hose-down cleaning, or dusty conditions. For submerged or extremely high-pressure wash-down environments, a higher rating (like IP67/IP68) may be needed.
Q4: What are the standard flange face-to-face dimensions for these wafer valves?
A4: The face-to-face dimensions generally conform to international standards such as ISO 5752, API 609, or MSS SP-67 for wafer-style butterfly valves. The exact dimensions vary by size and pressure class. We provide detailed dimensional drawings for each valve size upon request.
Q5: What is the difference between a Wafer Type and a Lug Type butterfly valve?
A5: A Wafer Type valve is installed between two pipeline flanges using long bolts that pass through both flanges and the valve body. It relies on the line flanges for support. A Lug Type valve has threaded inserts (lugs) on the valve body, allowing it to be bolted directly to each flange independently. This makes the lug type suitable for end-of-line service or where one side may need to be disconnected. The wafer type is generally more compact and economical.
Q6: Can you provide valves with materials other than those listed (e.g., for highly corrosive media)?
A6: Absolutely. As a manufacturer, we offer customization. We can supply valves with body materials like Stainless Steel 316/316L, Duplex Stainless Steel, and specialized coatings. Similarly, disc and seat materials can be selected (e.g., Alloy 20, Hastelloy, PTFE seats) to handle specific corrosive or high-purity media. Please provide your media and service conditions for a tailored recommendation.
Q7: What is the typical lead time for an order of these valves?
A7: Lead time depends on the order quantity, size, material specifications, and actuator configuration. For standard configurations in common sizes, we often have stock or can produce within a few weeks. For large, custom, or complex orders, the lead time will be longer. We provide an estimated delivery schedule with every formal quotation.
Q8: Do you provide documentation like test reports, material certificates, and manuals?
A8: Yes. We operate under an ISO9001 quality system, and standard documentation packages include a product manual, material test certificates for major components, and a factory test report (typically for shell test and seat leak test). Additional certifications or third-party inspections can be arranged upon request.
