The new aluminium type 'CMO' tank vent check valve is composed of a saltwater resistant, lightweight aluminium alloy ALMG4.5. This newest valve, which is available in sizes DN40 to DN400, has a slimline tiny design, is lightweight and has a high flow capacity. The typical 'CM' discharges on deck. If discharge on deck is not practicable, the innovative 'CMO' tank vent check valve can be installed in the piping system, permitting discharge straight overboard. Our CMO type has been tested and approved in compliance with the necessary requirements of the European Union Recognized Organizations Mutual Recognition process for Type Approval.(ABS, DNV/GL, LR, BV, CCS, KR/KRS, NK/ClassNK, PRS, RINA, RINAVE, RMRS/RS).
