More Information
Summary:The present invention relates to an apparatus and method for improved check valve technology used in flow meters, particularly compound/combo meters. The improved check valve technology may be comprised in a single piece module that (1) can easily be removed from the meter without disturbing the metering module, (2) has few or no complicated rollers and pins that require calibration, (3) requires little or no special training to remove, (4) does not require the meter repairperson to move relatively heavy objects, (5) comprises a seal as part of the check valve assembly simplifying seal inspection, seal removal and seal replacement; and (6) is secured in its housing using only external fasteners. The check valve module further comprises fluid hammer relief features.
