Double-acting actuator with positioner and solenoid valve
Thread Content
As the title suggests, I have a project at hand; the client chose the following components: a double-acting cylinder + a double-acting positioner + solenoid valves (2/5 way, capable of being used in 2/3 ways) + a pressure reducing filter. There is no control schematic, and it’s not clear what function he wants to achieve. Could some expert give some guidance on the standard connection method?
The Fisher locator can provide dual outputs for two-way valves
If there are no requirements for control functions, how to determine it?
Both types of double-acting cylinder switches need to be vented; it doesn’t matter
The intelligent locator enables the valve to move in both forward and reverse directions. A double-acting cylinder is just one type of cylinder. The two connection holes, located at both ends of the cylinder, can be used for air intake and exhaust. It should be a cylinder with angular travel, with the switch moving exactly 90°
With a locator, there is no need for a solenoid valve, but a pressure reducing filter is essential
The presence of a solenoid valve indicates that the valve is equipped with interlocks. It is essential to know what position the valve will be in when the power to the solenoid valve is lost, as well as what position it will be in when the air supply is cut off; otherwise, it will be impossible to configure the air circuit properly.
If it’s just a locator, it’s simple； The key point is that there is an additional solenoid valve as well.
This is very likely. Can an electromagnetic valve generally achieve interlock functionality?
