Festo
The Festo 4745223 is an industrial 2-way mechanical ball valve featuring a soft sealing principle and a manual hand lever with a slot direction indicator corresponding to the flow direction. Constructed with a cast stainless steel housing and a 50 mm inside diameter with a DN 50 nominal width, this 2/2 reversible flow component utilizes a 2 NPT fitting connection based on the ASME B1.20.1 norm. It operates with a nominal pressure PN of 63, a 420 m³/h flow rate Kv, and a breakaway torque of 40 Nm at nominal differential pressure across a medium temperature range of -20 °C to 200 °C for vapor, compressed air, inert gas, water, and neutral liquids.
