ABSTRACT:
A safety valve for precluding leakage of a fluid from a ruptured conduit. The inventive device includes a sensing conduit having a center bore and a matrix of bores concentrically positioned about the center bore. A valve is positioned in fluid communication with the center bore of the sensing conduit and normally permits passage of hydraulic fluid therethrough. A pneumatic actuator is mechanically coupled to the valve and fluidly communicates with the matrix of bores in the sensing conduit. The pneumatic actuator and the matrix of bores can be pneumatically pressurized such that a rupturing of the sensing conduit will effect closure of the valve to permit continued operation of a remainder of a hydraulic system.
