relief valve test equipment pressure safety valve testing machine online Spring safety valve setting test bench
Product Description
Safety valve On-line calibrator is a portable safety valve online calibration device developed for electric power, chemical, metallurgy and professional inspection agencies. The advantages of this product are reasonable structure, strong, easy to carry, stable performance, etc. It is suitable for on-line detection of various spring-type safety valves and pressure relief valves in boilers, pressure vessels and pressure pipes. The first one to create two kinds of central processing and data acquisition modes of “cold state” and “hot state” is the only product in China that can accurately use two methods for detection. It can detect the pressure of various safety valve spool opening heights to detect spring linearity. The product is fast, sensitive, safe and accurate. At present, it is the best cost-effective product in China.
