Product Description
The Festo KVZB is a pre-assembled ball valve actuator unit that combines a process ball valve with a pneumatic quarter-turn actuator in a ready-to-install configuration. Available for manual actuation with a hand lever, automatic actuation with a quarter-turn actuator, or controlled operation with a quarter-turn actuator and valve positioner, this configurable unit serves as a complete solution for on/off or modulating media control in process and factory automation applications.
Key Features & Advantages:
Pre-Assembled Complete System from a Single Source: Combines perfectly matched components—ball valve, quarter-turn actuator, pilot valve, sensor box/limit switch box, positioner, adapter kit, and hand lever—all pre-assembled and ready for installation, eliminating compatibility concerns and separate sourcing .
Flexible Actuation Modes: Supports manual operation with hand lever, pneumatic on/off actuation with quarter-turn actuator, or controlled operation with quarter-turn actuator and valve positioner for precise analogue positioning (e.g., 4–20 mA signal) .
Double-Acting or Single-Acting (Spring Return) Actuator: Configurable with pneumatic quarter-turn actuators in both double-acting (DA) and single-acting (SR) configurations, providing fail-safe spring return to a defined position in the event of pilot air loss .
ATEX Hazardous Location Certified: Available in variants compliant with EU Explosion Protection Directive (ATEX), suitable for use in explosive gas and dust atmospheres (Ex II 2GD) with ignition protection types c T6...T3 X (gas) and c T80°C...T200°C X (dust) .
Configurable via Online Tool: Supported by an online configurator that simplifies the engineering and procurement process—simply select parameters and the configurator suggests the right combination, complete with datasheets and CAD models matching your configuration .
