Festo
537974
Air solenoid valve VMPA2-M1H-B-S-G1/8-PI
The Festo part number 537974 is a 20 mm electrical 5/3-way pressurized piston gate valve featuring a normal nominal flow rate of 510 l/min, G1/8 pneumatic working ports, and an operating pressure range of -0.09 MPa to 1 MPa. Driven by a 24V DC operating voltage with piloted control and an external pilot air supply port, this component utilizes a soft sealing principle, mechanical spring reset, adjustable exhaust air function, and a reversible flow direction with IP65 degree of protection in the mounted state. It includes detenting and non-detenting manual override options, supports any mounting position, and carries c UL us recognition along with CE and UKCA markings per EMC and RoHS directives.

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.
