Abstract: An electromechanically-controlled ceramic based proportional valve is disclosed. The apparatus may be manufactured with an accompanying ceramic pressure breakdown orifice pack. The apparatus is designed to utilize the wear-resistant properties of ceramic valve components to control the flow of high-pressure fluids using a servo-driven mechanical actuator. The apparatus is designed to control the closing of the poppet valve to prevent slamming of the poppet head into the poppet seat during closing, further preventing wear and tear on the apparatus components. The accompanying pressure breakdown pack is designed to systematically reduce high pressure and high velocity water flow through the device to allow the water to exit at a prescribed lower pressure and flow rate. The breakdown pack also prevents harmful cavitation in the valve assembly by handling the cavitation internally rather than allowing it to propagate itself through the entire valve assembly.
