YT-305 Volume Booster

Brand: Rotork YTC
Request Information
The Rotork YT-305 Volume Booster Relay is used in pneumatic control valves, which receive the positioner’s output signal and supply an air pressure actuator to reduce response and adjusting time.
Features
  •  Supplies constant air pressure at the rate of 1:1
  •  By-passing control enhances safety of control valve
  •  Response to slight changes in input signal, which increases accuracy of output of air pressure to actuator
  •  Built-in 100-mesh screen filters dusts in the air
  • Supply/Outlet Connection: 1/4" NPT
  • Signal Connection: 1/4" PT or NPT
  • Pressure Ratio: 1:1 Signal: Output
  • Signal and Outlook Pressure: psig: 101 (bar: 7, kPa: 700, MPa: 0.7)
  • Supply Pressure: psig: 145 (bar: 10, kPa: 1,000, MPa: 1)
  • Flow Capacity 
    • Exhaust: 1.32 Cv
    • Output: 1.19 Cv
  • Material: 316 Stainless Steel
  • Temperature Range 
    • -20°C to 70°C (-4°F to 158°F)
    • -20°C to 120°C (-4°F to 248°F)
    • -40°C to 70°C (-40°F to 158°F)
