Used for waterjet cutting intensifier pump
The different from the high pressure union suction side is that high pressure has the Detection hole,low pressure has not Detection hole.
The union suction side aimed that water only can go in, can't go out. The surface has a test hole. The requirement of the surface smooth enough, the material hard enough, can guarantees the concentricity of the whole machine. Its interior is cone seal, the surface of inner hole that contacted with ball is very important, it is the key point to ensure quality.
