In pulp and paper manufacturing, where corrosive chemicals, fluctuating pressures, and humid environments are standard, actuator failure is not just inconvenient, it is costly. Selecting a suitable actuator for paper plant conditions means specifying a product that can maintain torque integrity, resist ingress, and perform consistently over years of cycling with minimal maintenance.
Kinetrol’s rotary vane actuators are engineered to deliver precise 90 degree motion without the internal wear prone components found in scotch yoke or rack and pinion alternatives. With no sliding seals, corrosion resistant housings, and the ability to operate in environments with moisture and airborne fibres, these actuators are ideally suited for the mechanical demands of paper mills. The sealed modular design allows for a compact installation and can be supplied with positioners and feedback systems, which are critical for process control and automation.
Field Proven Longevity: Green Liquor Application Case Study
A Kinetrol Model 14 double acting actuator was installed on an 8 inch full port valve within the green liquor and weak wash line of a US based paper facility. The valve is cycled twice daily to alternate flow between pipelines, preventing solids build up in the liquor transfer process. Despite the aggressive nature of the medium and the low cycle frequency, the actuator has now operated for over 10 years without requiring any maintenance.
This application highlights the actuator’s resilience in chemically aggressive, fibre rich environments, validating its suitability for critical control tasks in pulp and paper operations where unplanned downtime must be avoided.
