For opening pressure, vacuum, water pressure and ventilation performance testing of breather valves, compliant with GB, API and SY/T standards.
Breather Valve Calibration Sets are designed for the verification and calibration of breather valves used in atmospheric and low-pressure storage tanks. The system complies with multiple international and domestic standards and supports accurate testing of valve opening pressure, ventilation performance, and pressure resistance, making it suitable for petroleum storage and transport applications.
The ODMT Breather Valve Calibration Set is a dedicated test system for threaded and flanged breather valves with diameters ranging from DN15 to DN200mm.
It integrates precise pressure and vacuum measurement instruments, stable vacuum equipment, and a modular structure to ensure reliable and repeatable calibration results.
The equipment is divided into a control cabinet and a breather valve clamping table, connected by hoses. The vacuum unit operates with low noise and no vibration, ensuring calibration accuracy without interference. Multiple test functions can be performed on the same platform, improving testing efficiency.
