After we design and make clamp style brass fittings for PAP pipes, we also produce the corresponding clamp style brass ball valves mainly from size 1" to 3". This is the big size brass ball valves for PAP pipes, the work pressure is the same with the fittings for PAP pipes, normally 1.6MPb. Most of clamp style brass ball valves will use nickle palting surface treatment. We never use the steel ball , we always use good quality brass balls . Welcome OEM projects
