The reliability measures of the electric valve actuator mainly include: the electric valve actuator is equipped with an emergency manual device to avoid the situation that it cannot be used without electricity; The actuator has valve position indication and contact output, which can feed back the valve position in time; The motor of the actuator is equipped with overheating protection device, which is not easy to burn out; The limit switch of the actuator can save electricity and ensure the normal stroke position; And the special actuator also adopts a squirrel-cage closed structure, which is more durable and reliable.
