Festo
8191920
Ball valve unit VAPB-A-3/4-F-40-F03-PA10
The Festo 8191920 is a pneumatic 2-way ball valve featuring a quarter turn actuator and a soft sealing principle for in-line installation in any mounting position. Built with an Rp3/4 fitting connection, a nominal width DN of 20, and a nominal pressure PN of 40, this 2/2 valve handles a flow rate Kv of 41 m³/h across a medium temperature range of -10 °C to 200 °C. It operates at a pressure of 0.55 MPa to 0.8 MPa (5.5 bar to 8 bar, 79.75 psi to 116 psi) with a breakaway torque of 6 Nm, utilizing compressed air, inert gas, water without water vapor, or 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.
