Unidirectional Throttle Valve

Where finite adjustment is required to control actuators at very low speeds such handling fragile material or smooth process control the "-FM" series has been designed exclusively to meet this requirement. Effective orifice area has been reduced to 1/10th of standard series, but still retains 10 turns of the adjustment needle, (20 turns on the M5 size). This series comes complete with One-Touch fittings and is available in elbow and universal style construction. Currently available in Metric to suit tube sizes from 3.2mm to 10 mm OD, and thread sizes from M5 to ¼ R(PT)
