Abstract
High-pressure, micrometering valves requiring low-actuating torque are combined in a lightweight, portable pressure calibration console, housed in a common valve block. A manual pressure valve and a manual vent valve connect compressed gas from an internal storage cylinder to pressure measuring gages or transducers to be calibrated. Automatically actuated isolation valves connect and disconnect a vernier balancing cylinder assembly, permitting fine manual adjustment of calibration pressures as high as 10,000 psi. Positive shutoff combined with low-torque, fingertip control and non-jamming closure are provided by the frictionally-engaged valve components.
