Selection step

1 clear the use of the valve in the device or device to determine the working conditions of the valve: the application of media, working pressure, working temperature and so on

2 to determine the nominal diameter and connection with the valve pipe connection: flange, thread, welding and so on

3 determine the operation of the valve mode: manual, electric, electromagnetic, pneumatic or hydraulic, electrical or electro-hydraulic linkage

4 according to the pipeline medium, working pressure, determine the selected items within the valve casing and the working temperature of material: grey cast iron, malleable cast iron, ductile iron, carbon steel, alloy steel, stainless steel, copper alloy.

5 determine the type of valve: gate valve, globe valve, ball valve, butterfly valve, throttle valve, safety valve, pressure reducing valve, steam trap, etc.

6 determine the parameters of the valve: for the automatic valve, according to the different needs of the first to determine the allowable flow resistance, discharge capacity, back pressure, etc., and then determine the nominal diameter of the pipe and valve seat diameter

7 determine the geometry parameters of the valve: the length of the structure, the form and size of the flange connection, the height of the valve opening and closing direction, the size of the bolt hole and the number of connections, the overall size of the valve and so on

8 the use of existing information: valve product catalog, valve product samples, such as the choice of the appropriate valve products
