I used it for the check valve of the tank of the compressor, but in about two weeks the movement became awkward due to moisture, the inner frame caught diagonally and the backflow of air occurred. It seems not to be suitable for piping that may cause water stains and rust water inside pipes to pass.
It is compact, it can be installed without worrying about adjoining piping, and the degree of freedom of installation position (vertical pipe possible) is better than swing and lift, it is an excellent product. However, on the catalog of monoterough and on the net it is stated that the usable pressure is 0 to 1.37 MPa, but it does not work at 0.05 MPa (0.5 kg / cm 2). We did not have enough time to re-arrange and we reviewed lift chucks at nearby home centers and completed work. At least 0.5 MPa or more is considered necessary. Please check manufacturer's minimum usable pressure and correct the posting pressure.
