Recently, CNNC's large-diameter Y-type globe valve was successfully delivered to users.
The valve has a nominal diameter of DN600 and a pressure of 1500LB. All of them are made of F91. It is the largest diameter Y-type stop valve produced by China National Nuclear Technology. During the development and production of valves, China Nuclear Technology, Quality, Production and other departments worked closely to overcome multiple difficulties and delivered the batch of valves to the users as required. At present, the installation of the batch valves is progressing smoothly.
