They can be applicable on the pipelines transporting the oils, paraffin, liquid hydrocarbonic environments which are neutrally influencing latch details. Latches 30ch906br have a number of advantages: reliable and simple design; small construction length, small hydraulic resistance at completely open pass, giving of the environment in any direction, low price. Opening closing of a latch happens gradually and by that conditions for hydroblow in system are not created. Latches 30ch906br belong to a class of the restored fittings, thereby service life can be prolonged considerably. Consolidation of a spindle stuffing, in case of need it it is possible to replace or just to tighten for increase in tightness. Installation on the pipeline is allowed only by the drive up.
