Eccentric Hemispherical Valve-Top-Mounted Reduced Bore Structure

The top-mounted reduced bore eccentric hemispherical valve integrates the top-mounted installation structure. Compared with the traditional side-mounted structure, the top-mounted structure does not require dismantling the entire valve body from the pipeline system. Only the valve cover needs to be removed to inspect, maintain or replace internal components such as the valve core, greatly shortening maintenance time and reducing maintenance costs. The reduced bore flow passage design reduces the internal volume of the valve body and the consumption of raw materials on the premise of meeting the working condition requirements of valve circulation capacity, thereby lowering manufacturing costs and achieving energy saving.
