Pneumatic ball valve model presentation means
Dec 04, 2017

With the rapid development of China's industrial modernization, the valve usage is also increasing, and pneumatic ball valve to open and close fast, and can not only do the switch, cut off the use of, you can also control the flow and other advantages, as the most widely used types of valves one! However, due to the wide range of pneumatic ball valves, including the use of pressure, temperature and control of different forms, the corresponding ball valve models are not the same, in order to avoid mistakes in the selection of users, and to ensure the normal use of pneumatic valve, Valve companies hereby hereby provide pneumatic ball valve model description, to facilitate understanding and awareness of everyone!

Pneumatic ball valve model editorial description is mainly from the additional conditions pneumatic ball valve, the choice of driving mode, the connection of different forms, structural changes, the type of sealing material, the level of valve pressure and the valve body material and more convenient to explain, hope For the majority of users to help.

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.

Pneumatic ball valve model edit instructions:

1,Q: said ball valve;
