We are the first private enterprise that is engaged in the design and manufacture of electro-hydraulic servovalve in China. At present，its products includes HTPL801，HTPL802，HTPL803 and HTPL808 Double Flapper-Nozzle，Two Stage Electro-Hydraulic Flow Control Servovalves as well as HTS818 Three Stage Electro-Hydraulic Flow Control Servovalve.
The valves above mentioned are applicable for controlling position，velocity，acceleration and force of electro-hydraulic servo control system，which is widely applied to various fields such as metallurgy, light industry and engineering mechanism，machine building，large scale test facility，aerospace，shipping，radar，rtillery and etc. Those valves can replaceMOOG series servovalve.
We accept the consultation from different customer , we will supply the best service at every aspects .
We can take the major repairing for you and design the servo valve eplace your previous ones you are using .
