Lock Up Valve, YT-405, sense the main supply pressure and shuts down the air flow when the pressure is lower than setting level to avoid system shutdown or damages to pipelines.

-  Due to its compact size and light weight, lock up valve can be installed without a bracket.
-  It responses to less than 0.1kgf/㎠ pressure change/s. 
-  Epoxy power coating resists against the corrosion. 
-  100 mesh screen filters small dust entering into the unit.
