Function
The Cryogenic Ball Valve is designed to provide precise flow control in low-temperature applications, ensuring tight sealing and reliable performance. The cryogenic ball valve design is equipped with specially engineered seats and seals, designed to prevent leakage and ensure that the valve operates smoothly even at cryogenic temperatures (as low as -196°C or -321°F).
The valve works by using a rotating ball to either allow or shut off the flow of fluid. When the valve is in the open position, the full-bore design ensures that fluid flows freely with minimal pressure drop. When the valve is closed, the advanced seat design provides an effective seal, preventing leaks and maintaining system integrity in cryogenic systems. The spring-loaded mechanism ensures that the valve remains tightly sealed even under fluctuating pressures and temperatures.
Made from stainless steel, alloy steel, and cryogenic-grade materials, this valve ensures reliable operation under extreme pressure and temperature variations. The full-bore design of the ball valve minimizes flow restrictions and reduces pressure drop, while its integrated sealing system provides a secure shut-off under freezing conditions. The Cryogenic Ball Valve is engineered to offer precise flow control, longevity, and superior sealing performance, which are critical for industries that rely on the safe storage and transportation of cryogenic fluids.
