This micro opening safety valves are high pressure safety valves.
This micro opening safety valves are installed in refrigeration equipment and systems, when the pressure exceeds the specified value, the valve opens automatically to restore the pressure to normal and ensure safe operation.

Industrial refrigeration micro start high pressure safety valve


Introduction

      When in use, first open the main cylinder switch, and then turn the low-pressure gauge pressure adjustment screw clockwise to compress the main spring and drive the membrane, spring pad and ejector to open the valve. The imported high-pressure gas enters the low-pressure chamber from the high-pressure chamber through throttling and decompression, and passes through the outlet to the working system. Turn the adjusting screw to change the opening height of the valve, so as to adjust the throughput of high-pressure gas and reach the required pressure value.
