Product Description
The Festo VZBA is a ball valve actuator unit combining a pneumatic quarter turn actuator (single or double-acting DAPS series) with a stainless steel ball valve, available as 2 way or 3 way configurations . This pre-assembled unit offers an efficient, reliable solution for automated process and factory automation, ensuring that the flow is fully opened or closed in both directions for optimal flow rate control .
Key Features & Advantages:
Ball Valve Actuator Unit with Double- or Single-Acting Quarter Turn Actuator: Pre-assembled with the proven DAPS series semi-rotary drive; single-acting versions spring return to a safe position in case of pilot air failure, providing fail-safe functionality .
Stainless Steel Ball Valve: Features a high-alloy stainless steel (1.4408) construction, offering high corrosion resistance for trouble-free control of aggressive media or gases in piping systems .
NAMUR Connection Pattern for Solenoid Valves/Limit Switch Attachments to VDI/VDE 3845: The standardized NAMUR interface simplifies direct mounting of control valves and position feedback accessories (limit switch boxes or sensor boxes) without requiring separate brackets .
Flow is Fully Opened or Closed in Both Directions: The quarter-turn design ensures full flow without pressure drops when open, and a tight shut-off when closed, acting as a 2/2-way or 3/2-way valve .
Use in Zone 1, 21, 2, 22 (ATEX): Certified for use in hazardous areas with potentially explosive gas or dust atmospheres, ensuring safety and compliance .
