ABSTRACT:
A free-floating neutrally-bouyant, stemless, externally-guided, and abrasion-resistant valve for reciprocating pumps that quickly responds to pressure-gradient reversals across its sealing surfaces. The neutral buoyency is attained by means of a hollow air-tight or nitrogen pressurized valve shaft and lead ballast, whereas the valve is guided directly into its valve seat by means of radial guide fins affixed to the exterior of the valve shaft that centralize the free-floating valve within the valve throat downstream from the valve's sealing surfaces. The sealing surface at the valve is protected against erosion from abrasive fluids by a hardfaced fluid deflector just upstream from its sealing surface, whereas the valve seat is protected from erosion by a hardfaced fluid deflector just upstream from the valve seat.
