Ball valve unit VZBA-A-3/4-GGG-63-32L-F0405-V4V4T-PB60
This Festo 3-way ball valve with a pneumatic quarter-turn actuator features an Rp3/4 fitting connection, a nominal width DN of 20, and a 3/2 valve function based on EN 10226-1 and ISO 5211 norms. The soft-sealed assembly supports an operating pressure of 0.55 MPa to 0.8 MPa, a fitting nominal pressure PN of 63, an 18 Nm breakaway torque at differential pressure, and a Kv type L flow rate of 5.1 m³/h across a medium temperature range of -10 °C to 200 °C. Compatible with compressed air, inert gas, water without water vapor, and neutral liquids, the unit accommodates any mounting position via in-line installation and an F0405 flange hole pattern.

Request a QuoteWhy 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.
