VENN safety valve in JapanTechnical characteristics:

1. summary:VENN safety valve in JapanMainly installed in the boiler led a variety of pressure vessels, piping piping.
As its name suggests, it is a device for ensuring safety.
Japanese VENNWhen the pressure on the inlet side of the safety valve reaches the preset pressure, the safety valve will automatically run and open the spool to discharge the fluid so as to prevent the pressure from rising continuously. After running, when the pressure drops to a certain value, the valve will be closed again.
In view of the importance of safety valves, many regulations and standards have been formulated for safety valves.
