Festo
537973
Air solenoid valve VMPA2-M1H-J-S-G1/8-PI
The Festo 537973 is a 20 mm electrical 5/2-way bistable piston gate valve featuring a piloted type of control with an external pilot air supply port and reversible flow direction. This component delivers a normal nominal flow rate of 700 l/min through G1/8 pneumatic working ports across an operating pressure range of -0.9 bar to 10 bar at 24V DC. It incorporates a soft sealing principle, positive overlap lap, adjustable exhaust air function, and both detenting and non-detenting manual override capabilities while achieving an IP65 degree of protection when mounted. Built for any mounting position, it carries c UL us recognition along with CE and UKCA markings compliant with applicable 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.
