Festo
8031336
Stem actuated valve VMEF-STCZ-M32-M-G14
The Festo part number 8031336 is a 20 mm wide mechanical industrial component featuring a 3/2-way closed, monostable valve function with a soft sealing principle and zero overlap lap. This plate seat component delivers a normal nominal flow rate of 870 l/min through G1/4 pneumatic working ports, operating across a pressure range of -0.95 bar to 10 bar with an external pilot air supply port and a mechanical spring reset method. It accommodates any mounting position, supports a maximum switching frequency of 3 Hz, and must not be used as a mechanical stop.

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.
