YT-400 Lock Up Valve
Lock up valve YT-400 closes the passage of air flow piping by sensing the pressure of the main supply. It closes when the pressure is lower than the setting pressure in the event of fault conditions.
It can be installed in metal piping without an extra bracket owing to its small size and light weight. YT-400 reacts rapidly at a minute differential pressure below 0.1kgf/cm2. Corrosion resistance is excellent with epoxy powder coating. For special type, it is able to attach Limit switch or Indicator which makes to catch whether YT-400 is opened or shut.
