Festo
556346
Basic valve LCB-4-1/4
Engineered with a 50 mm width and a 4/2 monostable valve function, this Festo industrial component utilizes a pneumatic actuation method with a mechanical spring reset and a poppet seat design structure. The unit delivers a standard nominal flow rate of 600 l/min across a working and pilot pressure range of 2 to 10 bar, accommodating compressed air matching ISO8573-1:2010 [7:4:4] standards with NBR seals. Weighing 500 g with a CRC 2 moderate corrosion resistance classification, it features through-hole mounting, an M20x1 pilot air port 12, and four G1/4 pneumatic connection ports supporting medium and ambient temperatures from -10 to 60 °C.

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.
