Jet tube electro-hydraulic servo valve is a force feedback type electro-hydraulic control device that is driven by a permanent magnet torque motor as the core and consists of a pre hydraulic amplification stage through a jet tube and a receiver. According to the different stages of hydraulic amplifiers, jet tube electro-hydraulic servo valves are divided into single-stage servo valves, two-stage servo valves, and three-stage servo valves.
An electro-hydraulic servo valve is a hydraulic control valve that receives analog electrical signals and outputs modulated flow and pressure accordingly. It is a key component in electro-hydraulic servo control. Electro hydraulic servo valves have the characteristics of fast dynamic response, high control accuracy, high power output energy, and flexible signal processing. They are widely used in aerospace, shipbuilding, metallurgy, rail transportation and other fields.
According to the different structural forms of hydraulic pre stage, electro-hydraulic servo valves are divided into single nozzle baffle type, double nozzle baffle type, slide valve type, jet tube type, etc. Jet tube electro-hydraulic servo valve has the characteristics of strong anti pollution ability, high pressure efficiency and volumetric efficiency, and high reliability. It is one of the mainstream products in the electro-hydraulic servo valve market, second only to nozzle baffle electro-hydraulic servo valve.
According to the "2025-2029 Global and Chinese Jet Tube Electro Hydraulic Servo Valve Industry Research and 15th Five Year Plan Analysis Report" released by the New Thinking Industry Research Center, with the improvement of enterprise manufacturing level and the continuous development of downstream industries, the market size of jet tube electro hydraulic servo valves is gradually expanding. The global market size of jet tube electro-hydraulic servo valves is expected to reach approximately 920 million yuan in 2024, and it is projected that the market will continue to grow at a compound annual growth rate of 4.6% from 2025 to 2031.
The technology barrier for jet tube electro-hydraulic servo valves is high, and international companies such as Parker Hannifin and MOOG Moog dominate the global high-end market. The main units involved in the research and production of jet tube electro-hydraulic servo valves in China are CSIC 704 Institute, Hengtuo Hydraulic, Nanjing Servo, etc. Hengtuo Hydraulic focuses on the research and production of military and civilian jet pipe electro-hydraulic servo valves, and its products are widely used in aerospace, industrial robots, ships and other fields. Nanjing Servo's "FF-129 Jet Tube Electro Hydraulic Servo Valve CNC Intelligent Complete Equipment" has been selected for the "Three First and Two New" Technology Product Certification List in Jiangsu Province in 2025.
The development of China's jet tube electro-hydraulic servo valve market is still benefiting from the increasingly improved relevant standards. The national standard "Jet Tube Electro Hydraulic Servo Valve (GB/T 13854-2025)" issued by the State Administration for Market Regulation and the National Standardization Administration will be implemented from March 1, 2026. This standard specifies the classification, testing methods, inspection rules, and other contents of jet tube electro hydraulic servo valves.
Industry analysts from Xinsijie stated that with the continuous development of high-end industries such as aerospace, the market space for jet tube electro-hydraulic servo valves will further expand. Due to technological limitations, European, American, and Japanese companies dominate the global high-end jet tube electro-hydraulic servo valve market. With the gradual breakthroughs in technology by enterprises and research institutions, the high-end development of China's jet tube electro-hydraulic servo valve industry is accelerating, and its competitiveness in the global market is increasing day by day.
