Discussion on control valve actuators
Thread Content
This post was last edited by fumeiqing on 2011-9-18 at 17:00. Is a single-cylinder actuator for control valves faster or a double-cylinder actuator faster? I hope the experts here can give me some advice!
It’s related to the single cylinder, your spring, as well as the quick shut-off mechanism; when the spring force is strong enough and the displacement is large enough, then the closing or opening can be done quickly. In this way, one will be fast, while the other will be a bit slower. If you use two cylinders, it’s possible to achieve fast speeds for both, but the speed isn’t as fast as when a spring is used
It can’t be said simply in that way; single-cylinder and double-cylinder designs each have their own uses, and the choice between them depends on the process conditions involved, which takes into account various factors such as the structure of the control valve and its thrust
Thank you for the support from floors 2-4! I’ve learned it!
Agree with the third floor. . . . . . . . . . . .
Since adjustments are being made in any case, speed shouldn’t be the most important factor. When emphasis is placed on speed, it is usually applied to on/off valves. I don’t know what specific requirements the original poster has
