Seeking help regarding the ASCO 531 solenoid valve
Thread Content
Why are there two schematic diagrams for this solenoid valve? Also, the leads in each diagram are very different from those in the legends learned before; I ask the teacher to provide an explanation.
The one with three holes is the first type, called a two-way three-port; the one with five holes is the second type, called a two-way five-port
So, how many ports does this solenoid valve actually have?
It has two meanings: it can be used as a 2/3-way or 2/5-way solenoid valve
You need to take photos of the two sides to be able to see it; it’s not visible this way
This solenoid valve has a base plate, and there are two ways to arrange it: on the front or on the back! !
Used in conjunction with the base plate, which has markings on it
These are universal solenoid valves for two-way three-port and two-way five-port configurations. The double-acting actuator can be used as is, while the single-acting actuator requires a conversion plate to be used in two-way three-port mode; this is achieved by blocking one of the exhaust ports.
It is a pilot gas, a pilot-type solenoid valve.
