Product Description
The Festo VZBE is a 2/2-way stainless steel ball valve with a soft sealing PTFE seat, designed for reliable on/off control of media in both process and factory automation . Available with NPT or flange/welded connections, this mechanically actuated valve supports reversible flow and mounting in any position, making it suitable for demanding applications with compressed air, inert gases, water, steam, and neutral liquids .
Key Features & Advantages
Stainless Steel Construction with CRC 3-4: High-alloy stainless steel (1.4408) provides corrosion resistance up to CRC 4, suitable for aggressive media and harsh environments .
Wide Temperature and Pressure Range: Operates from -20°C to +200°C with nominal pressure PN63 (up to 63 bar), supporting steam and high-temperature fluids .
Soft Sealing PTFE Seat: PTFE seat and FPM seals ensure tight shut-off with low breakaway torque and excellent chemical resistance .
Versatile Connection Options: Available with NPT thread (ASME B1.20.1) from 1/4″ to 4″, flange to ASME B16.5, or weld ends, with ISO 5211 mounting flange for automation .
Manual Operation with Position Indicator: Hand lever actuation with slot direction indicating flow position, ensuring clear visual status .
