Proportional valves is a kind of output proportional to the input signal hydraulic valves. It can be continuous and proportional control flow pressure, flow and direction according to given input signal. But the ordinary valve can't continuous step control according to proportion, it is just single action type switch valves, the opening direction, opening amount or spring set force are constant,it can not automatic compensation control the target based on the information collected according to actual condition.
We are agency of Germany Argo-Hytos, Argo-Hytos specilzed in hydraulic technology more than 50 years, it is famous hydraulic components manufacturer.There are more than 1000 works and two big production base in Germany and Czech UPI, the control technology is in the leading pisition of the world hydraulic industry, the main products are variety complete valve, power unit, cartridge valve, proportional valve and related electronic control components straight acting reversing valve: CETOP02, CETOP05 pilot operated directional valve: CETOP07, CETOP08 superposition valve (flow control valve, pressure valve, check valve) : CETOP02, CETOP05 with direct acting pressure compensator proportional valve: CETOP02, CETOP05, etc.
Our company focus on intelligent control, electro-hydraulic servo system control more than 10 years time. We have a unique technical precipitation and innovation for Closed-loop control of the hydraulic system ! Our company has proportional valve controller and control software, can accomplish the precise control of servo hydraulic cylinder, and detect the displacement sensor signal from linear tranducer etc.,  control the accurate proportion valve so as to achieve to the closed-loop control the oil cylinder and speed accurately. My company has a large hydraulic engineering, such as dynamic theater system, auto theater systems.
