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.
The DBB Ball Valve (Twin Ball) requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
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.
The upper mounted ultra-low temperature floating ball valve is a valve suitable for ultra-low temperature environments, mainly used to connect or cut off low-temperature media.
