Description

1. Product Title

METSO NELES B1CU6/15 – B1C Series Double-Acting Pneumatic Quarter-Turn Valve Actuator

2. Product Overview

The METSO NELES B1CU6/15 belongs to the classic Neles B1C double-acting piston actuator series, engineered to deliver precise 90-degree rotary movement for industrial ball valves, butterfly valves and plug valves. It relies on dual compressed air drive to maintain valve position when air supply is stable, making it ideal for continuous modulating control and frequent on-off switching loops. Manufactured with high-strength cast housing, self-lubricated piston assemblies and corrosion-resistant internal components, METSO NELES B1CU6/15 achieves ultra-long mechanical cycle life and stable torque output under fluctuating air pressure. It complies with EN 15714-3 industrial actuator standards and ISO 5211 valve mounting interface, simplifies on-site assembly with standardized flange connection, and resists harsh conditions including vibration, humidity and electromagnetic interference in process plants to reduce unplanned valve downtime.
