Festo
8191926
Ball valve unit VAPB-A-1/4-F-40-F03-PB20
The Festo 8191926 is a 2-way pneumatic soft-sealing ball valve featuring a quarter turn actuator and an Rp1/4 fitting connection based on EN 10226-1. It operates at pressures from 0.55 MPa to 0.8 MPa (5.5 bar to 8 bar) with a nominal pressure PN of 40, a nominal width DN of 15, and a flow rate Kv of 5.9 m³/h across a medium temperature range of -10 °C to 200 °C. Designed with an F03 flange hole pattern, reversible flow direction, and any mounting position for in-line installation, this component utilizes compressed air, inert gas, water, or neutral liquids.

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.
