Ralston QTVC


Compressed Gas Volume Controller



The Ralston QTVC-0000-0-0 Compressed Gas Volume Controller performs both ultra-precise low-pressure differential and high-pressure static pressure calibrations with nitrogen using the same device with an external pressure calibrator (not included). The light weight, compact unit is equipped with a fine adjust piston as well as fill, balance and vent valves. The proprietary pressure balanced fine adjustment piston allows for extremely precise, finger-tip control of pressure at 0.03 psi (2 mbar), 3000 psi (210 bar), or any range in between. The soft-seated valves make filling and venting the system very precise.
