Online Safety Valve Calibration Testing
Safety valves ( Pressure Relief Valves) are very essential to the protection of lives and property, so regular testing is crucial to ensure that valves are functioning properly. But can you really be sure of the results if the test is not conducted under the stress of everyday conditions? Unsurpassed for accuracy, reliability and safety, the advanced technology of DORY online portable safety valve testing was developed to test safety valves while in position, under a full load, for consistently superior, reproducible results.
It is a portable safety valve online calibration device specially developed for electric power, chemical industry, metallurgy and professional inspection institutions. The product is reasonable in structure, powerful, easy to carry and stable in performance, and gathers all the advantages of similar products in China. It is suitable for on-line detection of opening pressure of various spring-type safety valves and pressure relief valves in boilers, pressure vessels and pressure pipelines. Two central processing and data acquisition modes, "cold state" and "hot state", can accurately use two methods for detection. The pressure at the opening height of various safety valve spools can be detected to detect the linearity of the spring. The product is fast, sensitive, safe and accurate. At present, it is a product with better price/performance ratio in China.
