Festo
525201
Solenoid valve MHP4-MS1H-3/2O-1/4-K
The Festo 525201 is an 18 mm electrical industrial component featuring a 3/2 open, monostable valve function and a pressure-relieved poppet valve design structure with a 4 mm nominal size. It delivers a standard nominal flow rate of 400 l/min across a working pressure range of -0.9 to 8 bar, utilizing a mechanical spring reset, soft sealing principle, throttleable exhaust-air function, and direct piloting with an IP65 protection class and c UL us recognition. This direct-acting unit supports a maximum switching frequency of 210 Hz with a 3.5 ms off switching time, 24 mm grid dimension, pushing manual override, and reversible flow with restrictions for working pressures from -0.9 to 0 bar in any assembly position.
