Haitima Pneumatic Actuators - Spring Return (Single Acting) Actuator

Please make your selection from the list of models shown below. All of the models below are the Haitima single acting (spring return) models offering air open spring close functionality. 

Haitima single acting pneumatic actuators offer as standard, air to open, spring to close functionality. Often referred to as spring return pneumatic actuators, they offer fail-safe functionality as the compressed springs will decompress and turn the Hitima actuator through 90 degrees should the air supply fail. In the standard configuration they can be called 'normally closed', however they can be configured reverse acting to give air to close, spring open, or 'normally open'.

Care must be taken when sizing Haitima spring return actuators as both the air stroke that compresses the internal springs, as well as the initial and final spring torques need to be considered when selecting Haitima actuators. Contact All Valves Online should need assistance when sizing Haitima valve actuators.
