Festo
4451856
Ball valve VZBM-3/4-RP-40-F-3T-F03-B2B3
The Festo 4451856 is a mechanical 3-way ball valve featuring a T hole, a nominal width DN of 20, and an inside diameter of 17.6 mm. Designed for in-line installation with Rp3/4 fitting connections and an F03 flange hole pattern, this soft-sealing component supports a nominal pressure PN of 40 and a reversible flow direction for compressed air, inert gas, water, and neutral liquids within a medium temperature range of -20 °C to 130 °C. It is based on EN 10226-1 and ISO 5211 norms, exhibits a breakaway torque of 8 Nm at nominal pressure, and includes a switching position indication where the slot direction corresponds to the flow direction.

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.
