ABSTRACT:
The hydraulic safety valve includes a housing defining a generally cylindrical shaped chamber having an opening at both ends of the chamber, and a chamber contained generally spherical shaped member. The hydraulic safety valve is suited for deployment in a hydraulic system wherein the main hydraulic unit is in fluid communication with a remotely located workpiece via hydraulic fluid lines. The safety valve interrupts or is attached to a hydraulic line in close proximity to the main hydraulic unit and functions to protect against substantial losses of hydraulic fluid from the hydraulic system as a result of workpiece or hydraulic line failure.
