Product Description
The Festo VZBC ball valve actuator unit combines a compact, flanged, stainless steel 2/2-way ball valve with a double-acting or single-acting DAPS quarter turn actuator, offering a pre-assembled solution for automated media control in pipelines . Featuring a NAMUR connection pattern to VDI/VDE 3845 for direct attachment of solenoid valves or limit switches, this unit is also approved for use in ATEX zones 1, 21, 2, and 22 .
Key Features & Advantages:
Ball Valve Actuator Unit with Double- or Single-Acting Quarter Turn Actuator DAPS: Pre-assembled with the DAPS series semi-rotary drive; single-acting versions ensure a defined fail-safe position (spring return) in the event of a pilot air failure .
Stainless Steel Ball Valve in Compact Design: Constructed from high-alloy stainless steel, providing high corrosion resistance (CRC 3 compared to standard brass) in a space-saving flange design ideal for tight installations .
NAMUR Connection Pattern for Solenoid Valves/Limit Switch Attachments to VDI/VDE 3845: Features the standardized NAMUR interface, allowing direct mounting of pilot valves and position feedback accessories (sensor boxes or limit switches) without requiring additional brackets .
Flow is Fully Opened or Closed in Both Directions: The quarter-turn design ensures full flow without pressure drop when open and tight shut-off when closed, acting as a reliable 2/2-way shut-off valve regardless of flow direction .
Use in Hazardous Areas: Certified for use in ATEX zones 1, 2, 21, and 22, covering explosive gas and dust atmospheres, ensuring safety in petrochemical or volatile environments .
