A105N forged steel floating ball valve is a valve device manufactured using forging technology, featuring a ball without a fixed shaft support. It relies on medium pressure to push the ball against the downstream seat, forming a single-side seal.
Structural Components
Valve Body: Made of forged steel, offering high strength and corrosion resistance to withstand high pressure and temperature. The body is typically designed in a two-piece or three-piece structure for easy installation and maintenance.
Ball: The key component, which floats under medium pressure to achieve automatic centering and ensure effective sealing. The ball surface is precision-ground for low roughness, reducing friction with the seat and extending service life.
Seat: Made of non-metallic materials (e.g., PTFE, RPTFE, PPL) or metal hard-seal structures. Non-metallic seats provide good sealing and corrosion resistance for general applications, while metal hard-seat designs suit harsh conditions (high temperature, high pressure, strong corrosion).
Stem: Connects the ball to the operating mechanism, transmitting torque. Typically made of stainless steel with heat treatment for high strength and toughness. To prevent leakage, the stem uses packing sealing or bellows sealing.
Operating Mechanism: Can be manual, pneumatic, electric, or hydraulic. Manual operation uses handwheels or worm gears, while pneumatic, electric, or hydraulic mechanisms enable remote and automated control.
Working Principle
When the stem is rotated manually or via the operating mechanism, the ball turns 90° to open or close the valve. In the closed position, medium pressure pushes the ball against the seat, forming a tight seal. When open, the ball rotates 90°, allowing fluid to pass through.
Performance Features
Excellent Sealing: The floating ball automatically centers under pressure, ensuring tight sealing with minimal leakage (achieving zero leakage standards).
Easy Operation: Low opening/closing torque allows for smooth and quick operation.
Long Service Life: Special surface treatment on the ball and seat enhances wear resistance, while the floating design compensates for wear, extending valve life.
Wide Application: Suitable for various media, pressures, and temperatures, with material and seal options for different conditions.
Compact Design: Small, lightweight, and space-saving, facilitating pipeline installation and maintenance.
