When a pressure signal is applied, the valve shaft moves in the direction
opposite that of the direct-acting actuator, but it follows the same
operating principle.
In the reverse-acting actuator, the valve shaft is pulled
into the actuator by the application of a pressure control signal.
When actuator travels in the direction of air supplied, then the actuator is called direct acting actuator.
A Direct Acting (DA) pneumatic thermostat increases branch line pressure as temperature increases. A Reverse Acting (RA) pneumatic thermostat decreases branch line pressure as temperature increases.

When changing indirect speech to direct speech, generally you need to change pronouns, tenses, time expressions, and sometimes the structure of the sentence. It is important to accurately represent what was said in the original indirect speech. Additionally, pay attention to punctuation such as quotation marks, capitalization, and commas.
