Volume booster relay, YT-300 is used in pneumatic control valve which receives positioner’s output signal and supply air pressure actuator to reduce response and adjusting time.

- 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.
