Festo
151195
One-way flow control valve GRLZ-1/4-B
The Festo 151195 is an industrial component featuring a supply air flow control non-return function with an internal thread G1/4 pneumatic connection 1 and an external thread G1/4 pneumatic connection 2. This screw-in component utilizes a slotted screw adjusting element, operates within an ambient and medium temperature range of -10 °C to 60 °C, and handles an operating pressure of 0.3 bar to 10 bar. It delivers a standard nominal flow rate of 610 l/min in the flow control direction and 450 l/min to 820 l/min in the non-return direction, while offering ATEX explosion protection 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.
