Masoneilan Booster Relays Model BR200 / BR400 4 Spool Hydraulic Control Valve

Masoneilan BR200/BR400 High Capacity Volume Booster Relays

Application

Flow sensitivity adjustment allows optimization for improved efficiency and safer operation in key pneumatic control valve applications.

Operation

Prior to applying supply pressure to the relay, open the bypass needle valve approximately one turn. After applying pressure, note response of actuator to open and close commands from the positioner. If excessive overshoot or hunting is seen, open needle valve until stable operation is obtained. If valve is sluggish, close needle valve until unstable operation occurs, then back off until stable operation is obtained. Turning valve clockwise (closing) speeds response but can lead to instability. Turning valve counterclockwise aids stability but will slow down the actuator's response. Proper setting provides stable operation and acceptable response time.
