Festo
The Festo 546151 is a servo-controlled diaphragm valve featuring a soft sealing principle, a 40 mm nominal width, and a 2/2-way, closed, monostable valve function with non-reversible flow direction. Designed for in-line installation with a G1 1/4 fitting connection and a preferred upright mounting position, this electrical component accommodates compressed air, inert gas, water, and neutral liquids via a solenoid coil type MH-... available as an accessory. Operating parameters include 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, alongside a 0.07 MPa pressure difference and 4 MPa burst and overload pressure limits.
