Fluke Calibration constant volume valves are pneumatically actuated needle valves with return piping connected to the inlet to a coaxial compensator. Needle displacements are matched by equal and opposite volume displacements on the compensator.
Constant volume valves are used in piston gauge cross floats, as well as applications where two high pressures must be disconnected and reconnected with minimal concern for both sides.
