What is the difference between proportional valves, servo valves, and control valves?
Thread Content
Regulating valves are easy to understand; they are commonly pneumatic or electric, with 4-20mA used to control the degree of valve opening. Are proportional valves generally of smaller size? A servo valve is a valve that is controlled with relatively high precision using a feedback signal related to its opening degree? Or does it refer to those servo valves that come with temperature or pressure signal control?
Proportional valves, servo valves – these are all used in hydraulic systems; it means more or less what you mentioned
Could you tell me how your servo valves are controlled?
For programming, it depends on whether you are adjusting the pressure or the stroke Use PID commands or write custom code to determine the valve position of the servo valve based on the difference between the desired command and the feedback; assess whether there is a fault by examining the feedback valve position
Are it usually 4-20ma signals, or are 0-10 options available as well?
It seems like they all have them; it depends on what type of valve you choose
