1.Product characteristics and application:
This Valve test bench is designed and manufactured with reference to similar products of Germany and GB4981 stabdard,It is suitable for sealing test of straight-through welded valves and straight- through flange connection valves , before and after installation. It is suitable for shell test, sealing test (low pressure sealing test and high pressure sealing test) and upper seal test (ISO5208) for GB4981, in order to prevent faulty valves from entering work site.
Features: simple operation, safe and reliable, sensitive test.
