90 Flow Control Regulators Component Materials Technical Characteristics Available with technical polymer, nickel-plated brass or aluminium bodies, with external or recessed adjustment screws, Flow Control Regulators offer precise adjustment, accuracy and compactness. Ø metric: 3 to 14 mm Regulations • RoHS • REACH • PED Advantages Productivity: • Higher maximum flow than standard regulators • Optimal control of the cylinder rod speed Accuracy: • Precise adjustment for accurate flow regulation • Long-term stability of flow Ergonomics: • External adjustment screw: easy to adjust ; Recessed adjustment screw: protects the adjustment mechanism • Can be rotated 360° during assembly • Compatible Fluids: Compressed air Other fluids: contact us • Working Pressure: 1 to 10 bar • Working Temperature: 0°C to +70°C -25°C to +70°C (metal version) Max.

Use is guaranteed with a vacuum of 755 mm Hg (99% vacuum). You will find all the flow rate characteristic curves (to 6 bar) for Flow Control Regulators at the end of the chapter. Nut: nickel-plated brass Adjustment screw: nickel-plated brass and polymer Gripping ring: stainless steel Adaptor: nickel-plated brass Seal: NBR Body: technical polymer or nickel-plated brass Seals: NBR Silicone-free C B A A C A C B A A C A C B A A A Uni-Directional (Exhaust Version) Non-return valve Adjustment screw Uni-Directional (Supply Version) Bi-Directional Version Models with Recessed Adjustment To control valve Operation The uni-directional models control the flow of air in one direction through an adjustable restrictor, while allowing full flow in the opposite direction. The bi-directional models control the flow of air in both directions. A more precise and constant flow regulation is obtained when the regulator is fitted directly onto the cylinder.
