Electric ball valve as an important industrial automation and control system equipment, due to its simple structure, easy operation, in recent years has been the use of more and more, not only can be used to cut off or connect the media in the pipeline can also be used for fluid Regulation and control! However, due to different conditions in the pipeline, the use of electric ball valve models are not the same! Electric ball valve users should elaborate on the preparation of methods and knowledge!
Electric ball valve model said:
Electric ball valve model that method
Ball valve attached code: V said the valve with V-shaped structure, D said low temperature, B said insulation, P said eccentric structure, U and S and DY more than that on the type;
Ball valve name code: Q said ball valve;
Ball valve drive code: 2 that electro-hydraulic, 3 that the turbine, 6 that pneumatic, 7 that liquid, 9 that electric, manual without a code;
Connection code: 1 for internal thread, 4 for flange, 6 for welding, 7 for clip;
Structure code:
Floating: 1 means through the runner, 2 means Y type tee, 4 means L type tee, 5 means T type tee,
Fixed: 0 means hemispheric straight through, 6 means four-way runner, 7 means through flow, 8 means L type tee, 9 means Y type tee,
Sealing material code: B Babbitt, F fluorine rubber, F46 lined fluorine, H rust steel, J Liner, M Monel, N nylon plastic, Monel P, Y cemented carbide, W valve body direct processing;
Pressure grade code: 16 means that the pressure is 16kg (1.6Mpa), the maximum can reach 64Mpa; 150LB means the pressure of American standard pound, the maximum pressure level up to 2500LB (150LB = 1.6MPA / 300LB = 2.5-4.0mpa / 400LB = 6.4 mpa / 600LB = 10mpa); 5K that Japan-class pressure, the maximum pressure 63K;
Body material code: A titanium and titanium alloy, C carbon steel, I chrome molybdenum steel, P18-8 Department of stainless steel, RMo2Ti Department of stainless steel, S plastic.
Electric Ball Valve Model Edit Description:
Stainless steel electric flange V-type ball valve
1, V: Valve body with V-shaped structure
