How to choose the right valve

Tianjin Haojie Valve Co., Ltd. discusses how to choose the right valve

Identify the use of the valve in the equipment or device to determine the working conditions of the valve: applicable medium, working pressure, working temperature, etc.;

Determine the nominal diameter and connection method of the pipe connected to the valve: flange, thread, welding, etc.;

Determine the way to operate the valve: manual, electric, electromagnetic, pneumatic or hydraulic, electro-hydraulic linkage;

According to the pipeline conveying media, working pressure, working temperature to determine the selected valve housing and internal parts of the material: cast steel, carbon steel, stainless steel, alloy steel, stainless acid-resistant steel, gray cast iron, malleable cast iron, ductile iron, copper Alloys, etc.

Choose the type of valve: Closed-circuit valve, regulating valve, safety valve, etc.

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

Determine the valve parameters: For automatic valves, according to different needs to determine the flow resistance, discharge capacity, back pressure, etc., and then determine the nominal diameter of the pipe and the diameter of the valve seat hole;

Determine the geometric parameters of the selected valve: the length of the structure, the form and size of the flange connection, the dimensions of the valve height direction after opening and closing, the size and number of bolt holes connected, and the overall valve size.
