In harsh gas environments, the lifespan of spherical float valves is collectively influenced by material corrosion resistance, particle erosion, and pressure fluctuations. Selecting 316L stainless
Floating ball valves rely on fluid pressure to push the ball and compress the downstream seal, making them suitable for low-pressure applications below Class 300.
For chlorine-containing environments, choose 2205 duplex stainless steel with a PREN over 35; for high-temperature sulfur-containing environments, use Inconel 625 with over 58% nickel; for
Sizes are customized from NPS 2 to 48; full port structure is mandatory if pigging operations are required; Pressure ratings strictly adapt from Class 150
The sphere surface needs to be sprayed with tungsten carbide to a thickness of 0.05 mm, achieving a hardness exceeding 68 HRC to resist wear;
Pressure ratings are typically selected between Class 150 and 2500; Conventional body material is WCB carbon steel, while CF8M stainless steel is specified for corrosive
Soft-seated side-entry ball valves (such as PTFE) are suitable for temperatures below 200°C and can achieve Class VI zero leakage, but they have poor wear
Carbon steel (WCB) is suitable for water and oil at temperatures from -29 to 425°C; Stainless steel (316) resists strong acids and withstands high temperatures
The seal utilizes a PEEK bi-directional valve seat resistant to high temperatures up to 260°C to ensure zero leakage; The stem features an anti-blowout stepped
Forged steel side-entry ball valves are forged under high pressure, resulting in a dense internal structure without porosity, extremely high strength, the ability to withstand
