The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
RAYS C-type ball valve adopts a double eccentric design: the rotational center (axis) of the C-ball is offset from both the geometric center (sphere) of the C-ball sealing surface and the sealing center of the seat. This double eccentric design results in a dual-vector cam motion involving both rotation and translation of the C-ball, facilitated by the stem being offset in two planes. When the valve is closed, the C-ball and the seat interact to create a cam-action wedge tightness, achieving a torque seal. The torque required for sealing is provided by a handle, gear, or actuator, ensuring a tight shut-off that is mechanically independent of springs or process pressure
The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
