PRIME MOVER™ uses a welded metal bellows (essentially a hermetic spring) as the force generating mechanism instead of a traditional piston. As a pressure differential is applied across the bellows, it compresses or extends. If external pressure is applied, the bellows compresses, extending the actuator. If pressure is removed, the bellows spring force retracts the actuator. Double actuating versions are also available.
The Senior Advantage
- All-welded construction to highest quality standards
- All metal / withstands exotic/corrosive fluids, etc.
- Zero friction / Zero leakage
- Trouble-free operation (accurate and repeatable)
