C-type Structure: The valve body of the C-type ball valve is designed to be similar to the shape of the English letter "C". This design helps to reduce fluid turbulence and pressure loss, while facilitating cleaning and maintenance.
Top-loading Design: The main components such as the ball and valve seat can be removed and installed from the top of the valve body,
which is convenient for maintenance and replacement without removing the pipeline.
Fixed Ball Design: The ball is fixed in the valve body and does not rotate with the flow of fluid, which helps to reduce the erosion of the ball by the fluid and extend the service life of the valve.
Ultra-low Temperature Materials: The valve is made of stainless steel, nickel-based alloy and other materials suitable for ultra-low
temperature environments, and uses sealing materials with good low temperature performance, such as PCTFE.
Thermal Insulation: The valve may be equipped with a thermal insulation layer to prevent external heat from entering the fluid and maintain
the fluid at an ultra-low temperature.
Material: Stainless Steel, Alloy Steel
Nominal Size: NPS 1/2"~24", DN 15~600
Pressure Rate: Class 150~2500, PN 10~420
Temperature Range: -196°C~+150°C
Operator: Manual, Pneumatic, Electric, etc...
Application Range: LNG, LPG, LNG low temperature conditions and long-distance pipelines such as oil, gas, and natural gas.
The cryogenic butterfly body can be provided in twostructural forms, namely flange connection and butt.welding connection (both with inspection ports). The body with inspection ports can replace the valveinternals online, making maintenance work extremelysimple, which is conducive to the rational use ofresourcesand saving maintenance costs.The extended valve cover + drip tray design ensures thatthe temperature at the stuffing box is above zero degrees!so that the connection between the stuffing and the stemwill not freeze and lock.
The C-type wear-resistant ball valve is a valve designed specifically for harsh working conditions, characterized by its eccentric ball setting and "C" - shaped channel. This design cleverly utilizes the translational characteristics of the sphere during rotation, achieving a "wedging" effect with the valve seat, thereby significantly improving the sealing performance. In addition, its ingenious upper and lower support axis positioning structure not only ensures the stability of the sphere, but also avoids tilting, allowing the medium thrust to be evenly dispersed, thereby extending its service life. This design not only optimizes the sealing performance, but also reduces the opening and closing torque and improves the opening and closing efficiency. Widely used in industries such as coal chemical, petrochemical, offshore platforms, LNG, etc.
The Side Entry Cryogenic Trunnion Mounted Ball Valve fixed ball valve is a type of fixed ball valve that adopts an upper mounted structure. The ball is installed and disassembled through the upper part of the valve body, and can work stably under ultra-low temperature conditions. When closed, the valve stem drives the ball to rotate, making the hole on the ball perpendicular to the valve body channel, thereby cutting off the medium; When opened, the valve stem drives the ball to rotate 90 °, aligning the hole on the ball with the valve body channel, and the medium can pass through.
