The Variable Suction Angle Valve is a new-modeled valve which is to be fitted at the end of cargo oil suction pipe on tankers, and has a variable suction area to meet with the flow rate required. Recently during past few years, the tankers became larger and larger and also the cargo oil pumps increased their pumping capacity. Accordingly the larger-sized suction bellmouth came into our special consideration. As one of rationalization of the cargo handling system of the tanker, the authors developed this new "Variable Suction Angle Valve", and two mammoth tankers equipped with these new type of suction valves have been built in their shipyard for Japanese ship owners. By adopting these valves you can expect following merits; 1. Stripping pipe lines can be ommitted and no inconvenience can be found in stripping operation. 2. Huge bellmouth is not required but the sucion mouth can be easily accommodated between bottom longitudinals. 3. The number of cargo valves which is hydraulically remote-controled can be decreased and cargoing operation more simplified. 4. Maintenance and inspection of the cargo suction valve can be made easier because this Variable Suction Angle Valve is more compact than the ordinary gate valve. 5. Cargo oil can be unloaded quicker than usual tankers which are not equipped with the Variable Suction Angle Valve.
