525101

Name: Festo 525101 Air solenoid valve MHA2-MS1H-5/2-2
Brand: Festo

Air solenoid valve MHA2-MS1H-5/2-2

The Festo 525101 is a 10 mm wide electrical 5/2-way monostable industrial component featuring a pressure relief poppet valve design, soft sealing principle, and mechanical spring reset. Operating on 24V DC within a pressure range of -0.09 MPa to 0.8 MPa, this IP65-rated unit delivers a normal nominal flow rate of 90 l/min through a sub-base pneumatic working port and includes adjustable exhaust air function alongside a non-detenting manual override. It carries c UL us recognition, RCM compliance, and CE and UKCA markings per EMC and RoHS directives, with a 2 mm nominal width and 14 mm width dimension permitting a minimum grid dimension distance of 4 mm for any mounting position.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
