Festo
525157
Solenoid valve MHA3-MS1H-3/2O-3-K
The Festo 525157 is an electrical 3/2 open, monostable industrial component featuring a pressure-relieved poppet valve design structure with a 14 mm width, 19 mm grid dimension, and 3 mm nominal size. It delivers a standard nominal flow rate of 200 l/min across a working pressure range of -0.9 to 8 bar, incorporating a mechanical spring reset, soft sealing principle, throttleable exhaust-air function, and direct piloting with a pushing manual override. Featuring an IP65 protection class, c UL us recognition, reversible flow direction with restrictions, reversible working pressure from -0.9 to 0 bar, a maximum switching frequency of 280 Hz, a 2.8 ms off switching time, and any assembly position, this unit operates reliably in demanding pneumatic systems.
