Product Mode： Fixed mode of products： Test Speed： Number of tests： Equipment size： Description: The cut-off valve flow test bench is suitable for testing the pressure drop and corresponding flow rate at different opening degrees under pressure conditions, automatically calculating and recording its flow coefficient (Cv/Kv value), drawing characteristic curves, and verifying that the flow capacity under the test is a key parameter affecting the refrigerant flow distribution and system efficiency of the air conditioning system. To accurately evaluate and control the quality of globe valves, specialized equipment is required to measure their flow coefficient (Cv value or Kv value) and pressure drop flow curve to ensure compliance with design specifications and provide data basis for product quality control and design verification.
