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.
Direct current does not reverse direction

Direct acting cholinergic drugs directly bind to and activate cholinergic receptors, while indirect acting cholinergic drugs increase cholinergic activity by inhibiting the enzyme acetylcholinesterase, which breaks down acetylcholine. Direct acting drugs include bethanechol and pilocarpine, while indirect acting drugs include donepezil and physostigmine.

A reverse acting thermostat works by opening the contacts within the thermostat when the temperature rises above the set point. This action breaks the circuit, turning off the heating or cooling system. Essentially, it operates opposite to a direct acting thermostat, which closes the contacts to turn on the system when the temperature falls below the set point.
dcrp = direct current reverse polarity
Direct current (DC) is the term used to refer to current that flows in one direction and does not reverse its direction. This is in contrast to alternating current (AC), which changes direction periodically.
