Seawater Butterfly Valve Actuators: How to Specify Coastal Corrosion Protection
Seawater Butterfly Valve Actuators: How to Specify Coastal Corrosion Protection Quick Summary: Specify seawater butterfly valve actuators as complete operating packages. Identify salt-spray, splash, flooding, washdown and condensation exposure; then define the coating system, enclosure protection, mounting hardware, cable entries and accessories. An IP rating addresses enclosure protection, while coating qualification addresses a different requirement. […]
Difference Between Single-Acting and Double-Acting Actuators
Compare single-acting and double-acting actuators by operating principle, fail-safe function, air consumption, torque output, control capability, maintenance, and application. Single-acting actuators use spring return for automatic fail-open or fail-close operation, while double-acting actuators use air or power in both directions to provide higher torque and more consistent control for demanding valve automation systems.
