Festo
The Festo 546169 is a servo-controlled diaphragm valve featuring a 2/2-way closed monostable function, a 50 mm nominal width, and a G2 fitting connection for in-line installation preferably in an upright position. Utilizing a soft sealing principle and electrical actuation via an MH-type solenoid coil ordered separately, this component regulates compressed air, inert gas, water, and neutral liquids with a non-reversible flow direction. It operates within a gaseous media pressure range of 0.07 MPa to 1 MPa and a liquid media pressure range of 0.07 MPa to 0.6 MPa, with a differential pressure of 0.7 bar, an overload pressure of 2.5 MPa, and a burst pressure of 4 MPa.
