Q: Pump, valve, these belong to the material?: The pump belongs to the equipment (electromechanical equipment), and the valve belongs to the pipeline material.

Q: Chinese valve and a valve which is better?: Look what valve you use, ah, these two can be ah!

Q: How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?: The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.

Q: What do you mean by "P54" in the valve z962y-p54 100V?: Applicable temperature 540 degrees centigrade；Applicable temperature 540 degrees centigrade

Q: 1/2, what does 1/4 valve mean? I don't understand. What does this number mean? Have a valve to introduce me, do not copy a pile of online introduction, I want to concise: It should be said that the diameter is represented by units per inch! 15mm 6mm nominal diameter valves representing metric units!

Q: Which valve can play a good regulatory role?: A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.

Q: What is the difference between a stop valve (a power station valve) and other valves?: High pressure, special material, complex structure, seldom manual operation.

Q: What are the ten major brands of China's valves?: Tianjin Gangyan guangheng special equipment Limited by Share Ltd is the leader Chinese special material valve industry, a joint venture with Chinese Gangyan established

Q: How do you calculate the flow of the valve?: Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.

Q: How are the types of valves classified?: Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion.
