Abstract

A continuous operation metering valve, based on true volumetric positive displacement technology, uses an innovative dual rack and drive pinion design that enables the valve (34) to dispense from one meter chamber (32) while the other meter chamber (32) is filling. This provides greater dispense cycle rates because it does not require a fill or reload period. With an optional encoder-controlled motor (42), the inventive metering valve is capable of almost unlimited precision dispensing with "on-the-fly" adjustment capability. The metering valve is easily disassembled and cleaned, using stainless steel wetted path components and Teflon seals for the widest range of chemical compatibility. An integral electronic board, mounted to the side of the valve, may be utilized to control the 4-way directional valve and motor direction (when not using a rotary encoder control).
