LF2 Floating Ball Valve: construction and material review
A floating ball valve is defined by its valve construction, while carbon, low-temperature or alloy steel selection depends on the process conditions and the specified material standard. Confirm bore, differential pressure and operating frequency when considering a floating ball construction. This page is an engineering enquiry guide, not a confirmed stock or approved manufacturing specification.
Technical selection checklist
| Design requirement | Construction review: operating torque, seat loading under differential pressure, cavity pressure behavior and fire-safe requirements. Verify drawing, pressure class, end connection and operating method for the selected size. |
|---|---|
| Material-grade review | Material review: Check design temperature, impact-testing requirements, corrosion allowance and any sour-service restrictions in the project specification. Confirm wetted versus pressure-retaining parts separately; a trim material does not establish body grade. |
| Engineering checklist | For floating ball valve: operating torque, seat loading under differential pressure, cavity pressure behavior and fire-safe requirements. For the specified grade: obtain traceability, manufacturing route and project-specific inspection scope. |
| Application and selection | Fit for service depends on medium composition, operating/maximum temperature, pressure differential, solids, cycling and shutoff performance. Confirm bore, differential pressure and operating frequency when considering a floating ball construction. |
| Documents to request | Request the drawing, technical datasheet, material bill of materials, end connection, seat construction, proposed tests, material certification and actuator details when relevant. Grade-specific availability and test conditions must be confirmed by a formal quotation. |
Information required for quotation
Send your RFQ, datasheet or MTO with the required ASTM or UNS material, nominal size, pressure class, end connection, seat material, design temperature, fluid service and quantity. Include inspection and document requirements if specified by your project.
Frequently asked questions
Does A350 LF2 automatically qualify this valve for a corrosive service?
No. Grade, temperature, pressure, medium chemistry, seat and trim materials all require review.
Can LF2 Floating Ball Valve be ordered in any ASME pressure class?
Not by assumption. Size, pressure class, end connections and actual design availability must be confirmed.
