Stainless Steel Floating Ball Valve
Essential Facts: Our Stainless Steel Floating Ball Valve
For applications demanding superior corrosion resistance and reliable shut-off, the stainless steel floating ball valve is an indispensable component. Its design, featuring a ball that is free to move or 'float' slightly within the valve body, provides a tight seal against the downstream seat under system pressure. This makes it an excellent choice for a wide array of industries, including chemical processing, water treatment, food and beverage, and general industrial services. When conditions require robustness against corrosive media, our stainless steel construction ensures long-term durability and performance. For projects involving less corrosive environments or different pressure ratings, you might also consider our Carbon Steel Floating Ball Valve. Specific connection requirements are met with our Flanged Floating Ball Valve, designed for secure bolting into pipeline systems. In scenarios with elevated system demands, our engineered High Pressure Floating Ball Valve offers the necessary resilience and safety.
Detailed Specifications of the Stainless Steel Floating Ball Valve
The performance of our Stainless Steel Floating Ball Valve is defined by a precise set of engineering parameters. Below is a comprehensive breakdown of its key features and technical data, presented to assist in your selection and specification process.
Core Design Features
- Body & Trim Material: ASTM A351 CF8 (304 SS) or CF8M (316 SS) for excellent corrosion resistance.
- Ball: Precision-machined stainless steel, chrome-plated or PTFE coated for reduced friction and enhanced sealing.
- Seats: Reinforced PTFE (Teflon) or PTFE composite for tight bubble-tight sealing and chemical compatibility.
- Stem: Blow-out proof design, integrated with the ball for a secure connection.
- Sealing: Low-friction stem seals and body gaskets ensure minimal torque operation and prevent external leakage.
- Operation: Quarter-turn (90°) manual operation via lever, wrench, or gearbox. Pneumatic and electric actuators available for automation.
- Fire-Safe Design: Optional design available with secondary metal sealing for emergency situations.
