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.
