Abstract: A New Three Stage 15,000 p.s.i. Balanced Valve, controlling fluid flows and pressures equally well in either direction, giving dependable leak proof operation with a very low control force.The first stage acts to gradually cut off the flow as a metering pin enters the orifice, the second stage seat is a standard 45 degree poppet valve closing directly after the metering pin cuts off the flow, the third stage positive shut off is made by teflon under extreme pressure forming a cut off point between the metering pin and the inside walls of the orifice, just below the 45 degree poppet valve.This needed high contact pressure is created by a unique pressure multiplier, a system in which the metering pin causes the self lubricated teflon to be telescoped smoothly without obstruction into a slightly smaller confinement while the valve is being fully closed. A coil compression spring is used to restore the teflon back into the low pressure confinement.

Abstract: With this improved system the final gas discharge temperature can be one hundred degrees lower than the water it heated.Two high velocity, self pressurized vortexes are created by two high speed impeller wheels, one in each stage of the two-stage heat reclaiming system, these vortexes draw the heat carrying discharge gas from the furnace into the two-stage heat exchanger, compressing and compounding it, creating higher heat levels, which allows more wasted heat to be recovered and used. The heat exchanging surfaces of the system are scrubbed by the maximum heat and pressure of these vortexes which have a velocity of many thousands of feet per minute, this action increases the thermal conductivity of these surfaces over 3.5 times, heating the water hotter and cooling the gas faster than the conventional system.
