BW - Ultra High Capacity Booster
High-capacity volume booster with independent supply and exhaust amplification for precise control.
Independent amplification control simplifies precise supply and exhaust tuning for optimal actuator performance.
Exclusive manifold mounting system eliminates fittings, reducing installation time and inventory costs.
Compact design delivers high Cv in a single device, optimising efficiency in space-constrained applications.
The IMI BW Ultra High Capacity Booster is engineered to deliver high-volume boosting performance for pneumatic valve actuators. Designed with independent amplification regulators for supply and exhaust, it ensures precise and efficient pressure control. The unit features a unique manifold mounting system that eliminates the need for fittings or nipples, reducing installation time and inventory costs. Available in aluminium or stainless steel 316, it is suitable for standard, offshore, and extreme environments. With a compact design, high Cv values, and a non-ejectable, lockable regulation screw, the BW booster is optimised for demanding applications requiring accurate pneumatic amplification.
