ABS Type Approval
Marine gearboxes and transmissions engineered for demanding maritime applications. Our worm gear operators deliver precise torque amplification, self-locking mechanisms, and reliable control for valve actuation in marine environments. Designed for integration with pneumatic and electric actuators, these gearboxes provide mechanical advantage for operating large valves while preventing backflow and accidental movement.

Self-locking mechanisms prevent backflow and accidental valve movement, while cast iron construction withstands harsh marine environments and corrosion.
