Ball valve unit VZBA-A-1-WW-63-T-22-F0405-V4V4T-PB60

The Festo 8191838 is a 2-way pneumatic ball valve featuring a quarter-turn actuator, soft sealing principle, and weld-on ends for in-line installation in any mounting position. Based on DIN 3202-S13 and ISO 5211 norms with an F0405 flange hole pattern, this 2/2 valve handles a nominal pressure PN of 63, a nominal width DN of 25, and an operating pressure ranging from 0.55 MPa to 0.8 MPa. It accommodates a medium temperature of -10 °C to 200 °C, achieves a Kv flow rate of 71.5 m³/h, and requires a breakaway torque of 17 Nm at nominal pressure.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
