The power station gate valve has small fluid resistance, and the internal medium channel of the valve body is
directly connected. The medium does not change its flow direction when the gate flows through the gate valve. The pressure is self-tightly sealed, and both ends of the valve are welded connections. The torque required for opening and closing is small, the body structure is simple, the manufacturing process is better, the sealing performance is
good, and the corrosion of the dense cover when the full opening is less. The scope of applications is wide.
Because the phenomenon of the long water hammer is not easy to occur. The medium can flow in any direction on both sides and easy to install.
◎ Design Standard: NB/T47044
◎ Main Material: Carbon steel, Stainless Steel, Alloy Steel, Etc.
◎ Size Range: NPS2~NPS24/DN50~DN600
◎ Pressure Level: Class600~ Class 2500/PN100~PN420
◎ Temperature Range: -29℃~650℃
◎ Application Scenario: The power station gate valve is generally used in the shape of the shape of the valve without strict requirements, but the use conditions are more harsh. Such as high-temperature and high-voltage thermal power plants such as power industries and oil refining and other fields.
RAYS Metal Seated Wear-Resistant Ball Valve is designed for extreme conditions characterized by high temperatures, high pressures, and abrasive media. Manufactured from premium alloy steel and enhanced with advanced hardening techniques, it offers exceptional wear resistance for both the ball and the seat. The hard seal design ensures superior sealing performance in harsh environments. Additionally, the valve features a robust construction and is easy to operate and maintain, significantly reducing maintenance costs. It is an ideal choice for heavy industries such as petrochemicals, power generation, and mining.

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.
