Volume booster relay, 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.
Design features
Large flow capacity. Specifically designed to be used in
conjunction with valve positioners.
Optimal sensitivity. Reacts to sudden change in
supply pressure.
Fixed deadband. Provides accurate and stable final
positioning of the valve.
Internal by-pass control. Improves system stability.
