Safety valve test bench -PLC control

Device description

Safety valve test bench is designed, manufactured and tested according to the national setting pressure adjustment, setting pressure detection, discharge pressure detection and tightness detection of various safety valves, combined with the actual working conditions, to assess its pressure safety performance, in line with the requirements of national standards for safety valves. Can realize the collection of automatic takeoff pressure, air tightness and pressure retention time, pressure, pressure difference setting, can be threaded type, flange type safety valve for verification.
