Pneumatic actuator with 4 piston. More compact than two piston pneuamatic actuator, more torque with same model compare two piston.

With more pistons in the actuator, it allows their diameterto be smaller while generating higher torque.Atthe same time, it means the size of the actuator can be more compact. The cube shape coupled with pistons traveling shorter distances minimizes size requirements while maximizing torque output. At thesame time,shorter piston travel and compact size greally reduces pressure requirements compared to other designs and results in reduced energy expenditures. they have an externalepoxy base layer and a second polyurethane paint to further reduce corrosion in demanding applications. Extended spray wash downs do not create corrosion problems for the actuator.
