What is a floating ball valve?
A floating ball valve is a valve in which the ball can float. Under the action of medium pressure, t...
The Stainless Steel Cryogenic Ball Valve is specially engineered to operate safely and reliably in ultra-low temperature environments down to -196°C, typically found in LNG, liquid nitrogen, liquid oxygen, ethylene, and cryogenic gas applications. The primary material used in the construction of stainless steel cryogenic ball valves is high-grade stainless steel. This material is chosen for its exceptional resistance to corrosion and its ability to maintain structural integrity at extremely low temperatures. The stainless steel body ensures that the valve can withstand the harsh conditions often found in cryogenic environments without degrading over time. Featuring an extended stem design (cryogenic bonnet), anti-leakage sealing systems, and precision-machined seats, this valve ensures consistent shut-off, low torque operation, and full thermal isolation between the actuator and cryogenic media.
