Festo
2101
One-way flow control valve GR-1/4
The Festo 2101 is a one-way flow control industrial component featuring G1/4 pneumatic connections on both ports and a knurled screw adjusting element for in-line installation. Constructed with a wrought aluminum alloy housing, this RoHS-compliant part supports an operating pressure range of 0.5 bar to 10 bar, an ambient and medium temperature range of -20 °C to 75 °C, and compressed air operation as per ISO 8573-1:2010 [7:-:-]. It delivers a standard nominal flow rate of 370 l/min in the flow control direction and 150 l/min in the non-return direction, weighs 80 g, and provides ATEX certification for zones 1, 2, 21, and 22.

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.
