Floating Ball Valve
The Qisheng Floating Ball Valve provides a simple yet highly effective solution for mid-to-low pressure applications. Utilizing the natural pressure of the medium to push the ball against the downstream seat, it achieves a bubble-tight, zero-leakage seal. Compact, durable, and fire-safe to API 607, these valves are ideal for chemical processing, water treatment, and industrial utilities. Available in forged and cast steel, they feature anti-static protection and an anti-blowout stem for enhanced operational safety.
Description
Qisheng High-Performance Floating Ball Valve
The Qisheng Floating Ball Valve is a versatile and cost-effective isolation solution for various industrial services. In this design, the ball is not fixed by a trunnion; instead, it “floats” between the seats. When closed, line pressure pushes the ball against the downstream seat, creating a secure, leak-proof seal. Its streamlined construction and high-quality materials make it perfect for general industrial, chemical, and petrochemical applications.
Key Product Features
- Reliable Seating: Designed with high-performance soft seats that provide a bubble-tight shut-off even at low operating pressures.
- Inherently Fire-Safe: Built with a secondary metal-to-metal seal to maintain integrity during high-heat events, meeting API 607 and API 6FA requirements.
- Advanced Stem Safety: The anti-blowout stem design features an integral flange at the bottom to ensure the stem cannot be ejected under pressure.
- Anti-Static Protection: Standard spring-loaded devices between the ball, stem, and body permit electrical continuity to prevent static buildup.
- Full & Reduced Bore: Available in both full and reduced bore configurations to meet specific flow and pressure drop requirements.
