Pneumatic valve actuator spacing
Thread Content
I would like to ask what is an appropriate spacing between the outer walls of the actuators for pneumatic valves with a diameter of less than 40
It is pneumatic valves placed side by side, not on the same pipeline
This question is difficult to answer. First of all, it depends on whether the pneumatic valve chosen is a control valve or a ball valve, as the actuators used for these two types of valves are different. For control valves, diaphragm-type linear pneumatic actuators are used; the horizontal installation dimensions depend mainly on the size of the diaphragm, and the size of the diaphragm in turn depends on the thrust required by the valve. To determine this, information such as the medium, operating temperature, operating pressure, and flow rate is necessary. Ball valves are rotary valves, so they are equipped with piston-type actuators. When the horizontal distance is large, the same parameters mentioned above are also required. In addition, it is necessary to consider whether a handwheel is needed
I think it’s necessary to see your pipeline layout and valve information to resolve this issue; it’s difficult to determine it based on simple descriptions alone. It is certain, however, that the spacing must be such as to facilitate the removal of the flange bolts; 50 might be sufficient for the pipe spacing, but if it makes it difficult to remove the bolts, then there is still a problem.
