Fisher® VBL Volume Booster 

The Fisher VBL volume booster is used in conjunction with a positioner on a throttling control valve to increase stroking speed. The booster incorporates fixed deadband, soft seat construction, and an integral bypass restriction to eliminate positioner saturation problems that can occur with volume boosters that do not have these features. The volume booster delivers high-volume output for fast stroking when large, rapid input signal changes occur.
