Stellar Industries 47141 Gresen V20 Air Actuator – 1/8" NPT

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar Industries 47141 Air Actuator is a pneumatic replacement actuator designed for compatible Gresen V20 sectional hydraulic control valves. It features a 1/8-inch NPT air connection and converts pneumatic pressure into the mechanical movement needed to shift the valve spool.

Replacing a worn or leaking actuator helps restore responsive hydraulic function control. It can correct air loss, incomplete spool movement, intermittent operation, and hydraulic functions that fail to engage or return properly.

What This Part Is Used For

The Stellar 47141 air actuator mounts to a compatible Gresen V20 directional control valve. When air pressure is applied, the actuator moves the hydraulic valve spool to control the connected equipment function.

Common Reasons For Replacement

Compressed air leaks from the actuator
Hydraulic valve fails to shift
Controlled function operates intermittently
Actuator sticks or responds slowly
Valve spool does not travel completely
Internal seals or diaphragm are damaged
Actuator housing is cracked or corroded
The 1/8-inch NPT air port is damaged
