Pneumatic Diaphragms Actuator Valves are classified in: double acting (air-open; air-close), fail open (air-close; spring-open) & fail closed (air- open, spring-close).

Thanks to the shells and diaphragms, the resistance of the Pneumatic Actuators is designed to withstand high pressures in continuous operation and thus avoid excessive weight. In addition, the number of parts of the Pneumatic Actuator is minimal, so that the replaceable parts it contains can be easily disassembled and are protected against the elements.

The maximum pressure of 6 kg / cm² (85 psi).
