Balanced Floating Piston Valve for Ultra-High Pressure, High-Volume Liquid and Gaseous Flow Control

C-Suite Services, LLC (C-Suite) will produce at least one manufacture-ready, full-scale design for the licensed technology of the Balanced Floating Piston Valve. This design is intended as a “drop-in” replacement for an existing valve used in rocket engine component testing. The operating environment, pressures to 15,000 psi and flow rates of 1,000 lbm/sec of Gaseous Nitrogen, have proved problematic for the existing valve designs. High cost of repairs and limited life has resulted in an increase in cost for testing.C-Suite is the NASA licensee of the valve, which was designed to resolve the issues created by the high pressure, flow, and acoustic vibration environment at NASA Stennis Space Center (SSC) rocket engine test stands.. This innovative design eliminates the valve stem and stem seals, as well as the need for conventional actuators, which are the frequent source of failures and fugitive, often toxic propellant emissions. The innovative valve is called "Floating Piston Valve" (FPV); it does not have anymoving parts that are connected to the atmosphere andno adjustments are required. The flow path through the valve is all 100% axisymmetric, meaning that the forces generated by the flow through the valve create only radial forces that cancel, or create axial forces that either cancel or are controllable. The FPV's internal piston is balanced such that the seating force is immune to the pressure drop across the valve greatly improving seat wear and providing much longer, useful life without maintenance and refurbishment interruptions. The FPV is simpler to manufacture (5 parts vs. hundreds of parts for comparable ball valves) and is expected to have far greater utility (600+ duty cycles vs. 20-30 duty cycles for comparable ball valves). Finally, because there are no moving parts connected to the atmosphere, it willeliminate fugitive emissions, many of which are toxic and waste costly propellant chemicals.
