Volume booster relay, YT-305 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.
