Product Overview

The Valmet Neles B1CU Double-Acting Pneumatic Cylinder Actuator is designed for reliable automated operation of rotary valves in industrial process control systems. Manufactured by Valmet under the Neles brand, this actuator uses compressed instrument air to generate rotational torque for opening, closing, and positioning compatible quarter-turn valves. Its double-acting piston mechanism provides controlled movement in both directions, supporting accurate valve operation and dependable industrial performance.

Part of the Neles B1C Series, the B1CU features a rugged pneumatic cylinder design, articulated lever mechanism, and corrosion-resistant construction for demanding operating environments. It supports both modulating and on-off valve control applications and is compatible with suitably sized ball, butterfly, and other rotary valves. Its durable construction makes it suitable for oil and gas processing, chemical manufacturing, power generation, water treatment, and industrial automation.

// FAQs

Questions about this part?

Our engineers can confirm fit before you order. Contact support.

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.
