Festo
1686639
Ball valve VZBA-3/4"-GG-63-T-22-F0304-V4V4T
The Festo 1686639 is a mechanical 2-way ball valve featuring a soft sealing principle and an Rp3/4 fitting connection with a nominal width DN of 20 and an inside diameter of 20 mm. Built with an F03 and F04 flange hole pattern based on DIN 3202-M3, EN 10226-1, and ISO 5211 norms, this component supports a nominal pressure PN of 63, an actuating torque of 14 Nm, and a flow rate Kv of 45.6 m³/h for compressed air, inert gas, water without water vapor, and neutral liquids across medium temperatures from -10 °C to 200 °C. It provides a reversible flow direction, any mounting position for in-line installation, a slot direction matching the flow direction for switching position indication, no manual override, and RoHS-compliant materials.

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.
