Product Overview
The Fisher 2625-12 Pneumatic Volume Booster is designed to improve the operating speed and responsiveness of pneumatic control valve actuators in industrial process automation systems. Manufactured by Fisher, an Emerson brand, this pneumatic volume booster increases the volume of compressed air delivered to an actuator in response to pressure signals from a valve positioner. Its fixed 1:1 input-to-output pressure ratio enables rapid actuator movement while supporting accurate valve positioning, stable flow regulation, and reliable operation in demanding industrial applications.
Part of the Fisher 2625 Series, the 2625-12 features a durable pneumatic relay mechanism, an adjustable bypass restriction, and soft-seated valves that help reduce unnecessary air consumption. Its high-flow design enables faster actuator stroking during significant changes in control pressure while allowing smoother movement during smaller adjustments. Designed for integration with pneumatic valve positioners and suitable air supply regulators, the booster supports industrial automation in oil and gas processing, chemical plants, power generation, water treatment, and manufacturing facilities. The related Fisher 2625-9 is another volume booster configuration within the same product family.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
