Festo
525138
Air solenoid valve MHP3-M1H-3/2G-1/8
The Festo 525138 is a 14 mm wide, electrically actuated 3/2-way closed monostable pressure relief poppet valve featuring a direct control type and soft sealing principle. This component delivers a normal nominal flow rate of 200 l/min through G1/8 pneumatic working ports, operating at pressures ranging from -0.09 MPa to 0.8 MPa on a 24V DC supply. Built with IP65 degree of protection, mechanical spring reset, non-detenting manual override, and adjustable exhaust air function, the unit supports any mounting position with a minimum grid dimension distance of 5 mm and carries c UL us recognition.

Request a QuoteWhy 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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
