Power Station Swing Check Valve

The power station swing check valve is mainly suitable for the pipelines of the various systems of thermal power station to prevent the medium from flowing. Compared with other valve products, the power station swing check valve-outbound valve is high -temperature and high pressure. It is a unique and tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The power station swing check valve -type stop valve has the design characteristics of ordinary spinning -type stopping valve. The valve petals rely on the flow of the medium to open and close the valve. Because the valve petals do not rub with the valve seat before closed, the cover wear is reduced to effectively extend the service life of the valve.…

Features & Benefits

The power station swing check valve has a small fluid resistance, and the internal medium channel of the valve body is directly connected. The 

medium does not change its flow direction when it flows through the stop valve. The pressure is self-tightly sealed, and both ends of the valve are 

welded connections. The valve petals are closed quickly, the water hammers are low pressure, the body structure is simple, the production is better, the sealing performance is good, and the dense cover is less erosion. The scope of applications is wide.


General Information

Application Scenarios: The power station swing check valve is generally used in places with harsh service conditions, such as high temperature and high pressure thermal power plants, power industry, petroleum refining and other fields.
