A reset relief valve with a body having an inlet port, an outlet port, and piston defining an enclosed chamber, where the piston is disposed in the body and moveable between a first position at which the piston is disposed in fluid flow-blocking relationship between the inlet port and the outlet port of the body and a second position at which the piston is removed from that position, an electrically motivated worm drive operably connected to the piston. for controlled smooth movement of the piston responsive to pressure readings in the system. A preferred embodiment includes data acquisition software for monitoring data and storing pressure and other data to control the operation of the valve and a handheld controller. |
