Product Overview:

The opening and closing member of the protective gate valve is the gate,whose movement direction is perpendicular to the fluid flow.The gate valve can only be fully open or fully closed,and cannot be used for regulation or throttling. Our protective gate valve incorporates design innovations and process improvements based on references to certain foreign products,which have enhanced both the internal quality and external appearance of the product.It is strictly designed and manufactured in accordance with national valve standards.

Product Features:

External Structure: Referencing foreign products,it features the advantages of being lightweight,practical,aesthetically pleasing,and having good safety performance. Under our company's strict implementation of standards, the tensile and compressive strength of the valve body material has been greatly enhanced,with uniform stress distribution and an attractive appearance.
