Festo
8191923
Ball valve unit VAPB-A-1 1/2-F-25-F0405-PA40
The Festo 8191923 is a pneumatic 2-way ball valve with a quarter turn actuator, featuring a soft sealing principle and an in-line installation design with an Rp1 1/2 fitting connection. Built to EN 10226-1 and ISO 5211 norms with an F0405 flange hole pattern, this component handles a nominal width DN of 40, a nominal pressure PN of 25, and an operating pressure range of 0.55 MPa to 0.8 MPa. It supports reversible flow rates up to 200 m³/h, a breakaway torque of 19 Nm at nominal pressure, and a medium temperature range from -10 °C to 200 °C for compressed air, inert gas, water, and neutral liquids.

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.
