Recently, SNY Valve manufactured an extra-large diameter wedge gate valve with a designed diameter of 60 inches and a pressure class rating of 150, for a polysilicon project in northwest China

Design Features

• Low fluid resistance and short structural length

• Reduced operating force with unrestricted flow direction of the medium. 

• Enhanced corrosion resistance of sealing surfaces.

• Relatively simple physical structure and a well-established manufacturing process

"Designing and manufacturing ultra-large diameter valves pose greater challenges. In the valve design process, we conduct finite element simulation analyses to assess strength, stiffness, and flow characteristics, ensuring safety and optimal performance under working conditions. Special installation and maintenance facilities, along with designated areas, are essential for assembling and testing the performance and strength of ultra-large diameter valves, using specialized testing equipment."

"Thanks to the joint efforts of our entire team, this oversized valve successfully passed the sealing experiment on its first attempt, serving as a testament to our advanced technology and a guarantee of product quality. Customers have also unanimously recognized this significant achievement."
