Product Description
The Festo VZBM-A is a pre-assembled ball valve actuator unit combining a brass ball valve (VZBM series) with a double-acting or single-acting DFPD quarter turn actuator, offering a ready-to-install solution for automated media control . Available as a 2/2-way unit with pipe thread to EN 10226-1, or as a 3/2-way unit with drilled L-hole or T-hole configurations, this unit ensures flow is fully opened or closed in both directions .
Key Features & Advantages:
Ball Valve Actuator Unit with Double- or Single-Acting Quarter Turn Actuator DFPD: Pre-assembled with the DFPD series rack-and-pinion actuator, offering torque range from 10 to 480 Nm, rotation angle up to 180°, and available in single-acting (spring return fail-safe) or double-acting configurations for flexible automation .
Brass Ball Valve with Low Torque for Compact Drives: Nickel-plated brass housing with chrome-plated brass ball. The valve's low breakaway torque enables combination with smaller, space-saving DFPD actuators without loss of function, optimizing installation space .
2/2-Way or 3/2-Way with L-Hole or T-Hole Configurations: Available as a 2-way ball valve actuator unit for simple on/off control, or as a 3-way unit with drilled L-hole (flow diversion) or drilled T-hole (mixing/alternative supply concepts), both with pipe thread to EN 10226-1 .
NAMUR Connection Pattern to VDI/VDE 3845: Features NAMUR interface for direct mounting of solenoid valves and limit switch attachments (sensor boxes or end switches), simplifying system integration .
Flow is Fully Opened or Closed in Both Directions: Quarter-turn design ensures full flow without pressure drop when open and tight shut-off when closed, with reversible flow direction for flexible pipeline installation .
Wide Pressure, Temperature & Media Compatibility: Operates with nickel-plated brass housing, HNBR/PTFE/FPM seals; supports medium temperatures -15°C to +130°C, nominal pressure PN25-PN40, flow rates up to 243 m³/h, compatible with inert gases, water, compressed air, and neutral liquids .
