electro hydraulic servo valve

Description

We are the first private enterprise that is engaged in the design and manufacture of electro-hydraulic servovalve in China. At presentï&frac*4;Œits products includes HTPL**1ï&frac*4;ŒHTPL**2ï&frac*4;ŒHTPL**3 and HTPL**8 Double Flapper-Nozzleï&frac*4;ŒTwo Stage Electro-Hydraulic Flow Control Servovalves as well as HTS**8 Three Stage Electro-Hydraulic Flow Control Servovalve. The valves above mentioned are applicable for controlling positionï&frac*4;Œvelocityï&frac*4;Œacceleration and force of electro-hydraulic servo control systemï&frac*4;Œwhich is widely applied to various fields such as metallurgy, light industry and engineering mechanismï&frac*4;Œmachine buildingï&frac*4;Œlarge scale test facilityï&frac*4;Œaerospaceï&frac*4;Œshippingï&frac*4;Œradarï&frac*4;Œrtillery and etc. Those valves can replace domestic FF series servovalve or imported MOOG series servovalve.
