Product Description
The Festo VAPB is a ball valve unit combining a nickel-plated brass 2/2-way ball valve with a pneumatic quarter-turn actuator, available as a pre-assembled complete system for automated media control . Designed for in-line pipe installation with reversible flow, this unit operates on compressed air, inert gases, water, and neutral liquids, featuring an ISO 5211 mounting flange and NAMUR port pattern for direct attachment of solenoid valves or limit switches .
Key Features & Advantages
Pre-Assembled Complete System from a Single Source: Ready-to-install unit combining double-acting quarter-turn actuator DAPS or DFPD with VAPB brass ball valve, eliminating separate sourcing and compatibility concerns .
Brass Ball Valve with Full Flow in Both Directions: Nickel-plated brass housing (CW617N) with hard-chrome-plated brass ball, PTFE seat seals, and reversible flow direction ensures full opening or closing of media flow with low breakaway torque .
NAMUR Connection Pattern to VDI/VDE 3845: Standardised NAMUR interface allows direct mounting of solenoid valves and limit switch attachments for position feedback without additional brackets .
High Flow Capacity with Wide Pressure/Temperature Range: Delivers Kv flow rates from 41 to 121 m³/h (depending on size), supports medium temperatures from -20°C to +150°C, and nominal pressure PN25 to PN40 for versatile industrial applications .
ISO 5211 Mounting Flange with Corrosion Resistance: Features F03, F04, F05, or F07 flange hole patterns per ISO 5211, with corrosion resistance class CRC 1 (low corrosion stress) and RoHS compliance .
