The Top Entry Cryogenic Floating Ball Valve is a valve suitable for ultra-low temperature environments, mainly used to connect or cut off low-temperature media.
RAYS Side Entry Floating Ball Valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute Standard API 608&API 6D British standard BS 5351 and generally conform to American Society of Mechanical engineers standard ASME B16.34 valves are available in a complete range of body/bonnet materials and trims.
The Non-Rising Stem Gate Valve is also called the rotating stem gate valve. Stem and nut are arranged on the gate plate, handwheel rotation drive valve stem rotate to lift the gate, usually there is a trapezoidal thread at the bottom of the valve stem and the rotation movement is turned into a linear motion through the limit slot between the valve stem and the gate body and the gate body and the gate, that is, the operation torque is turned into operation thrust. When the valve is turned on, when the height of the gate is equal to the diameter of the valve 1: 1: 1, the channel of the fluid is completely unblocked, but at the run, this position cannot be monitored. In actual use, the vertex of the valve stem is used as a sign, that is, the position that is unmoved as its full opening position. The non-rising stem gate valve has the design characteristics of the ordinary wedge-type gate valve. The valve body has a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
