Festo
541658
Air solenoid valve MFH-3-1/4-24-NPT-EX
The Festo part number 541658 is an electrical industrial component featuring a 3/2-way, closed, monostable valve function with a 73 mm width and a 5 mm nominal width. Operating at 24V DC within an operating pressure range of 0.15 MPa to 0.8 MPa (1.5 bar to 8 bar), this piloted unit delivers a normal nominal flow rate of 800 l/min through 1/4 NPT pneumatic working ports. It includes a mechanical spring reset method, an adjustable exhaust air function, a soft sealing principle, a negative overlap lap, a detenting manual override, and a non-reversible flow direction with a 29 ms off switching time. Protected to IP65 and certified by FM 3026030 with US explosion protection for Class I, II, and III (Div. 1 and 2) and EPL Gb/Gc, the unit supports any mounting position.
