Volume booster YT-300 and YT-310 makes the valve function’s speed fast with providing large air flow rate to actuator.

  • Speed and accuracy is excellent with supplying air pressure at the rate of 1:1 steadily.
  • It makes to improve the stability with control of By-Pass.
  • It is an acute reflection of the change of signal pressure.
  • It has a fixed deadband because this is controlled by the seat-to-seat dimension of the supply and exhaust plugs.

 

Lock Up Valve

YT-400

Lock up valve YT-400 closes the passage of air flow piping with sensing the pressure of main supply pressure when the pressure is lower than the setting pressure due to accident and so forth.

  • It is able to install with metal piping without extra bracket due to small size and light weight.
  • YT-400 reacts susceptibly at the minute differential pressure below 0.1kgf/cm2.
  • Corrosion resistance is excellent with epoxy powder coating.
