Forged Steel Floating Ball Valve
Product Introduction
The Forged Steel Floating Ball Valve is a quarter-turn gate valve. Under pipeline pressure, the ball presses against the downstream seat, forming a tight seal. This design is ideal for medium- and low-pressure pipelines in industrial systems.
Product Advantages
Floating Ball Seal
The ball moves slightly under pipeline pressure, pressing against the downstream valve seat to ensure a tight and reliable seal.
Quick Quarter-Turn Operation
Opening and closing requires only a 90° rotation, saving time and reducing operational difficulty.
Reliable Shutdown Performance
The Forged Steel Floating Ball Valve effectively prevent leaks of water, oil, gas, and chemical fluids.
Wide Range of Industrial Applications
Suitable for oil and gas pipelines, chemical plants, water treatment systems, power plants, and HVAC systems, etc.

FAQ
Q: How does the floating ball design work?
A: In a floating ball valve, the ball is not fixed but allowed to move slightly downstream under pressure, pressing against the seat to achieve a tight seal. This design simplifies operation and reduces leak risks.
Q: What specifications should buyers check before purchasing?
A: Key specifications include pressure class (Class 150–900 / PN16–PN100), size range, body material grade (A105, F22, stainless steel), seat material (PTFE, RPTFE, PEEK, metal), end connection type (threaded, flanged, welded), and temperature range.
Q: Where are Forged Steel Floating Ball Valves commonly used?
A: They are used in oil & gas pipelines, petrochemical plants, power plants, water systems, and industrial fluid control where durability, pressure resistance, and reliable sealing are required.
Q: What are the temperature and pressure limits of these valves?
A: Forged steel valves typically handle pressures from PN16 to PN100 (Class 150–900) and temperatures ranging from -29°C to 425°C, depending on seat and material selection.
Q: What factors affect the price of a forged steel floating ball valve?
A: Price depends on size, pressure class, forged steel grade, seat type, certifications (API, ISO, CE), and optional features such as lockable handles, fire-safe design, or anti-static devices.
Q: Can these valves be used for corrosive media?
A: Yes, especially when made from stainless steel or with corrosion-resistant coatings. Seat material and body selection are critical to ensure compatibility with the specific medium.
