Feature: Adjustment FunctionThis throttle valve controls the flow of fluid by changing the cross section etc. It can be used to control flow, regulate pressure, save energy, improve efficiency, protect the system and much more. Abrasion and Corrosion ResistantThis flow control valve has a highly developed surface plating process. The selected H58 brass gives it excellent mechanical and corrosion resistance properties. It is hard, strong and meets the requirements of mechanical parts and can be used for long periods of time in harsh environments such as humidity, acid and alkaline, and high temperatures. As for the electroplated nickel film, it also adds the advantages of high stability, wear resistance and corrosion resistance to this throttle. Highly ClosedThe pipeline cylinder control valve also features a stainless steel spring and a zinc alloy ferrule. Both springs and ferrules are corrosion resistant, high strength and pressure resistant, and they provide a strong connection and hold, preventing leakage and external media intrusion. PreciseThe use of high-strength plastic, sealing rubber rings, thread sealant, high-precision spools and finely adjustable screws not only meet the standards of the machine's internal pipe joints, but also enable rapid adjustment of gas flow, making them indispensable pneumatic speed control components for precision. Wide Range of ModelsThis pneumatic speed control valve is available in 5 models, depending on the cross-sectional area of the pipe, with an outside diameter of 4mm/0.16in, 6mm/0.24in, 8mm/0.31in, 10mm/0.39in and 12mm/0.47in, to meet your needs.
