Fluke Calibration’s constant volume valve is a pneumatically actuated needle valve with a return line connecting the inlet to a coaxial compensator. Needle displacement is matched by an equal and opposite volume displacement on the compensator.
Fluke Constant Volume Valve
The constant volume valve is used in piston gauge crossfloats and other applications in which two high pressures need to be disconnected and reconnected with minimal purturbations on either side.
