The Festo part number 542019 is a mechanical 3-way ball valve featuring an L hole design and a soft sealing principle for line installation with an Rp2 process valve connection. Constructed with a 1.4408 high alloy steel non-corrosive housing, this DN 50 component accommodates a 40 mm inside diameter, a nominal pressure of 63, and an actuation torque of 37 Nm across a medium temperature range of -10 to 140 °C for neutral fluids and inert gases. It provides a reversible flow direction with a Kv flow rate of 53.7 m3/h at a tolerance of +/- 20 %, a switching position indicator where slot direction equals flow direction, and F05 or F07 flange hole patterns without manual override.
