摘要： A remote valve actuator includes an elongated enclosure having a tension spring therein maintained in a tensioned condition by a releasable link which will separate in the event of fire or other exigency to release the tension in the spring. A cable extends between the enclosure and a rotary-actuated valve, where it is attached to a handle of other actuating means. A coupling within the enclosure couples force from the spring to the cable, for pulling of the cable to actuate the valve, upon release of the link. The cable can be of indefinite length to locate the auxiliary actuator some distance from the valve. Manual operation is also provided by the remote actuator.
