Besides the functions of general check valve, axial flow check valve can realize zero leakage with its double-sealed seat. There are advantages of small fluid resistance, small water pressure, good flow pattern, quick response to pressure changes, and small overall dimensions thanks to unique design of Venturi streamlines. It’s the optimum choice for oil-gas transportation pipeline network system home and abroad, especially for oil pumps.
CHWP
ï¼check valve with function of piggingï¼
Model: ACHP

Description: DIPPER CHWP is applicable to the pipelines which requires purging and pigging. In normal working condition, it prevents backflow and when pipeline cleaning is needed, just operates it to the position that it corresponds to a part of the pipeline such that ensures the smooth work of pipeline cleaning.
Performance Feature:
1. Backflow-preventing and pigging;
2. Compact structure, easy installation;
3. Long service life, no obstruction, and reliable operation;
4. Zero leakage;
5. Various disc structures, wide range of application.
