The Power Plant Check Valve has low fluid resistance, and the internal medium passage of the valve body is straight. When the medium flows through the stop valve, its flow direction does not change. It adopts self-tightening pressure sealing, and the two ends of the valve are usually welded connections. The valve disc closes quickly, the water hammer pressure is small, the shape structure is simple, the manufacturing process is good, the sealing performance is good, and the sealing surface is less eroded when fully open. It has a wide range of applications.

Cryogenic Gate Valve is an opening and closing device used for fully opening and fully closing. The opening and closing component of ultra-low temperature gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape, and the wedge angle varies with parameters.
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.
Mainly suitable for cutting off or connecting pipeline media in various systems of thermal power plants. Applicable media: non corrosive media such as water and steam. The characteristics of forged steel valves compared to other valve products are high temperature and high pressure, unique self sealing design, and the higher the pressure, the more reliable the seal. Due to its unique performance, technical characteristics, and working conditions, the product has also developed unique features that cannot be replaced by other products.
