Festo
165663
One-way flow control valve GRLA-M5-B-CT
The Festo 165663 is an industrial component featuring a one-way flow control function for exhaust air with dual M5 pneumatic connection ports and a slotted head screw adjusting element for threaded mounting. It operates within a working pressure range of 0.2 to 10 bar and an ambient and medium temperature range of -10 to 60 °C, supporting filtered compressed air with 40 µm filtration that can be either lubricated or unlubricated. Constructed with a nickel-plated screw-in stud, wrought aluminum alloy regulating screw, and NBR seals, this 11 g component delivers a standard nominal flow rate of 95 l/min in the flow control direction and 76 to 95 l/min in the non-return direction.

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.
