Spring-Diaphragm Actuators

• Allied ASD series spring-diaphragm rotary actuator is designed and manufactured using spring-diaphragm technology and crank link principle, good output torque stability and high output torque continuity, especially suitable for high precision valve position analog control, such as V-type ball valve, segment ball valve, etc. The actuator is able to be driven by gas, water, or mineral-based hydraulic fluid media, even at a low supply pressure (1Bar). The actuator operates normally at a temperature range of -60℃ (-76 ℉) to 200℃ (392 ℉).
