Frequently Asked Questions (FAQ)
-
What does "Fire-Safe" mean for this butterfly valve?
The "Fire-Safe" designation indicates that the valve is designed to maintain sealing integrity and prevent external leakage for a specified period when exposed to fire conditions, typically tested to standards like API 607/6FA. This is crucial for safety in hydrocarbon or flammable fluid services. -
Can this valve be used for both onshore and offshore applications?
Yes, while it is designed with marine-grade corrosion resistance, its compliance with API 609 and fire-safe features make it suitable for a wide range of onshore industrial, oil & gas, and fire protection systems as well. -
What is the advantage of a gear operator over a simple lever?
A gear operator provides a significant mechanical advantage, reducing the operating torque required. This makes opening and closing easier, safer, and more precise, especially for larger valve sizes (e.g., over 10") or higher pressure classes like Class 300. -
Are the Class 150 and Class 300 valves identical except for pressure rating?
No. While they share the same design standard (API 609) and fire-safe features, Class 300 valves are generally built with thicker components (body, disc, shaft) to withstand higher pressures. Material specifications and testing pressures also differ accordingly. -
Do you provide specific fire-test certificates for the valve?
The valve is designed and manufactured to meet fire-test requirements. Specific fire-test certification reports from third-party laboratories can be provided upon request and may involve additional lead time and cost. -
What are the available end connection types?
The valve is typically available in wafer or lug style connections. The choice depends on your piping system design and bolting requirements. Both options can be discussed during the ordering process. -
Is the valve suitable for cryogenic or very high-temperature services?
The standard temperature range is -20°C to 200°C. For applications outside this range (cryogenic below -20°C or high-temp above 200°C), special material selections and design modifications are available. Please consult our engineering team for custom solutions. -
What is the typical lead time for an order?
Lead time varies based on order quantity, specific configuration (size, material, pressure class), and current production schedule. Generally, for standard sizes and materials, lead times are competitive. We provide accurate timelines upon receipt of your detailed inquiry.
