Since SA and DA cylinders are a pretty common subject, I want to make this comment....
Some SA cylinders can look like a DA cylinder with two ports, but rod side port is always connected to return or straight to tank. Even if rod side is connected to the Control Valve port, there can be a spool SA valve spool, that makes the cylinder SA.
SA or DA is best determined by checking if there is "power down" or not.
