Festo
151165
One-way flow control valve GRLA-1/8-B
The Festo 151165 is an industrial component featuring an exhaust air flow control non-return function with G1/8 pneumatic connections on both ports and a slotted screw adjusting element for screw-in mounting. It delivers a standard nominal flow rate of 340 l/min in the flow control direction and 260 l/min to 420 l/min in the non-return direction, operating within a pressure range of 0.3 bar to 10 bar and temperatures from -10 °C to 60 °C. This unit complies with ATEX Zone 1, 2, 21, and 22 explosion protection standards, maintains ISO 14644-1 Class 4 cleanroom suitability, and functions with compressed air per ISO 8573-1:2010 [7:4:4] where oil lubrication is possible.

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.
