Cast iron copper inlaid square gate

1、 Product Overview
Cast iron copper inlaid square gate is a specialized equipment for water conservancy engineering, made of gray cast iron or ductile iron casting, with copper strips or rubber embedded in the sealing surface, in compliance with CJ/T300-1992 of the Ministry of Construction and AWWA standards in the United States. Its core function is interception and water level regulation, suitable for water supply and drainage, flood prevention, irrigation, and water conservancy and hydropower projects. It achieves bidirectional water stop through wedge devices, with a sealing gap of ≤ 0.1mm.
