Valve Cover

1. Core Structure & Core Value
The core structure of a three-piece ball valve consists of a "left valve body + middle valve body + right valve body" (the three parts are connected by bolts). Its valve cover is usually integrated with the left/right valve body (or serves as an end cover integrated with the valve body).
The core value focuses on "full disassembly for maintenance + reliable repeated sealing". It is the optimal choice for scenarios where "pipes are inconvenient to disassemble and repair after being fixed".
2. Core Value of Valve Cover with Alloy 625 Overlay Welding
The core value of three-piece ball valves with Alloy 625 overlay-welded valve covers lies in "balancing reliability and cost-effectiveness under extreme working conditions".
It is particularly suitable for industries sensitive to "corrosion, high temperature, and high pressure" and that prioritize maintenance efficiency. As a high-end solution, it addresses the issues of "frequent failure of ordinary valve covers and high maintenance costs".
