Lock-up valve

The lock-up valve YT-400 closes the passage of air-flow piping by sensing the pressure of the main supply pressure when the pressure is lower than the setting pressure due to accidents and so forth. It can be installed with metal piping without extra bracket due to small size and light weight.

 

  • YT-400 reacts susceptibly at the minute differential pressure below 0.1kg/f
  • Corrosion resistance is excellent with epoxy powder coating
  • For special types, it is able to attach a limit switch or indicator, which displays whether the YT-400 is opened or shut
