Pneumatic diaphragm control valve – flow characteristics
Thread Content
Pneumatic diaphragm control valve – flow characteristics: equal% type, linear type. Can someone help me understand this? I didn’t finish elementary school. Thank you! ! !
In other words, the flow rate is proportional to the opening degree, of course under the condition that the pressure difference before and after remains constant. Some valves are of the quick-opening type; for example, ordinary butterfly valves see a rapid increase in flow rate, and after 70% the valve is essentially fully open
