Manual threaded ball valve model Q11F-16
Commonly used materials are: stainless steel, brass;
Threaded ball valves are further divided into one-piece ball valves, two-piece ball valves, and three-piece ball valves.
The one-piece ball valve is an integrated type composed of a ball, a PTFE ring and a lock nut. The diameter of the ball is slightly smaller than that in the pipeline, similar to the wide-type ball valve.
The two-piece ball valve is composed of two parts. The sealing effect is better than that of the one-piece ball valve. The diameter of the ball is the same as that of the pipeline, and it is easier to disassemble than the one-piece ball valve.
The three-piece ball valve is composed of three parts, the bonnet and the intermediate valve body. The three-piece ball valve is different from the two-piece ball valve and the one-piece ball valve in that it is easy to disassemble and maintain.
