ABSTRACT:
A pilot operated relief valve which includes a non-flowing modulated pilot valve and a main valve. The pilot utilizes a torsion device in connection with transducers and valves. The transducers relate variations in pressure within the valve system to the torsion device. The torsion device, in turn, acts to open and close various ports of the pilot valve so as to achieve modulated relief of overpressurized fluid from a pressure system. In addition, the torsion device can be manipulated to provide for easily achieved and accurate set pressure positions.
