Festo
8048978
Swivel lever valve VMEF-VL-M52-M-G14
The Festo 8048978 is a 5/2-way monostable industrial component featuring a mechanical piston gate valve design with a quarter turn actuator and a 20 mm width. Operating within a pressure range of -0.95 bar to 10 bar, this directly controlled unit delivers a normal nominal flow rate of 1200 l/min through G1/4 pneumatic working ports utilizing a soft sealing principle and positive overlap lap. Featuring a mechanical spring reset, a 45-degree cam angle, and a maximum switching frequency of 2.5 Hz, it operates with compressed air as per ISO 8573-1:2010 [7:-:-] where oil lubrication is possible and required for further use.

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.
