Model 2625 and 2625SST Volume Booster

Volume Booster

The Fisher® 2625 or 2625NS volume booster is used in conjunction with a positioner on a throttling control valve to increase stroking speed. The 2625NS is a nuclear-service version and uses elastomeric components that better withstand high temperature and radiation environments. 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.
