The selection of automatic control valves should follow the five principles of safety, science, reliability, applicability, economy and on-site working conditions, such as the size of the valve diameter, medium, temperature, material and pressure to select the appropriate valve

The valve model compilation standard of Chinese valve enterprises shall be implemented in accordance with JB T 308-2004 "Valve Model Preparation Method", and the valve model should usually indicate the valve type, driving mode, connection form, structural characteristics, nominal pressure, sealing surface material, valve body material and other elements

Self-controlled valves refer to the use of electric, pneumatic, hydraulic or electromagnetic drive and other methods other than human power to control the valve

Butterfly valve, also known as flap valve, is a simple structure of the regulating valve, which can be used for the on/off control of low-pressure pipeline medium, and the butterfly valve refers to a kind of valve that rotates around the valve shaft to open and close the shut-off part (disc or butterfly plate) as a disc.

The operating principle of pneumatic valves is generally a one-piece design, and all double-acting and single-acting actuator models have the same cylinder block and end cap, which can be easily changed by adding a spring or removing a spring

Solenoid valve is a commonly used actuator in industrial process control system to realize remote control or program control of the system medium, and it is converted into mechanical force to achieve the purpose of switching

1. The selection step 1 of the control valve is the type of control valve There are many types of control valves, and the commonly used ones are straight single seat, straight through double seat, angle, diaphragm, small flow, tee, V-ball, butterfly, sleeve type,

Solenoid valve selection guidanceThe solenoid valve selection should follow the five principles of safety, scientificity, reliability, applicability, economy and on-site working conditions, such as: the size of the valve diameter, working pressure, and medium species
