Actuators

Bellows are used in actuator assemblies to transfer pressure or temperature into a linear motion. Edge welded bellows allow a long stroke, excellent media compatibility, and high temperature and pressure capabilities. Edge welded bellows also provide extreme flexibility in the design to fit size, weight, and movement requirements and allow the movement to be driven by internal or external forces. Bellows actuators can be used in valve applications, where pressure is internal or external to the bellows. Custom flanges, end pieces and hardware can be integrated into the assembly. With the extreme flexibility of edge welded bellows technology, axial movement and lateral offset are possible solutions. With sizes less than half an inch in diameter, bellows actuators can reduce the size of traditional actuators in hydraulic and pneumatic systems.
