valve low leakage test

Low leakage valve introduction

For all kinds of valve products by conventional water pressure, air pressure test can not be determined, and need to use more scientific means and precision instruments to detect small external leakage, this microwave leakage of the external environment is called micro-leakage. Valves that meet micro-leakage requirements have been widely used abroad, and with the construction of foreign companies in China, some valves with toxic media flammable or explosive media have micro-leakage valves.
