Three-piece Flange Ball Valve

Our Dafugui three-piece flange ball valve features a full-bore design, ensuring smooth flow of water or media. The core seal is made of top-grade materials such as PTFE to ensure zero leakage. What's more, its three-piece structure makes maintenance super simple.

This Q41F-16P Three-piece flange ball valve features a full-bore design for high flow capacity. Seals made of high-quality materials such as polytetrafluoroethylene (PTFE) effectively prevent leakage. The valve body and internal components are constructed of stainless steel for corrosion resistance. Its flexible design facilitates installation, operation, and maintenance, making it widely used in industrial fluid control.

Dafugui's Three-Piece Flange Ball Valve brand features a three-piece, three-piece design. Its full-bore design allows for unrestricted fluid flow. The valve body and internal components are constructed of stainless steel, effectively withstanding the continuous flow of various corrosive media and ensuring long-term stable operation.


Many valves, despite being installed on a large pipe, provide minimal flow through the valve.

Our Ball Valve is different. It uses a full-bore design, and the internal channel diameter is basically the same as the diameter of your pipe. The fluid can flow freely and at its maximum. The fluid resistance can also be minimized, which can improve the delivery efficiency of your system and make your pumps and equipment run more easily and efficiently.

The three-piece flange ball valve is bolted together in three sections. If you need to repair or replace a sealing ring, you don't have to remove the flanges from the pipe. Simply unbolt the center section, and the ball can be easily removed for maintenance.

Leakage is a serious concern in fluid control; we use high-quality, high-performance materials such as PTFE (polytetrafluoroethylene) for valve seats and seals.

Our valve bodies and internal components are primarily made of stainless steel, ensuring long-lasting service.
