The -FM series has been specially designed for applications requiring fine adjustment to control actuators operating at very low speeds, such as when handling fragile materials or controlling smooth processes. The equivalent orifice area has been reduced to 1/10th that of the standard series, but still retains 10 turns of the adjustment screw, (20 turns for size M5). This series is supplied with push-in fittings and is available in straight or angle construction. Currently available in mm to suit tube ODs from 3.2 to 10 mm, and with threads ranging from M5 to ¼ R(PT)
