SST series designed mainly for steel manufacturer is the superior model of conventional HOP series which has more than 2000 units of shipping record since its release in year 1992.
SST series rotate its operation axis to corresponding position with the point which was commanded by instrumentation signal, 4 to 20mA from user's operation panel.
E/E positioner, hydraulic channel switching valve, hydraulic pump, and cylinder, etc. are all packaged in a compact body. It receives external instrumentation signals with a positioner in recognizing any deviation from the current position. SST series have been improved to higher speed, higher accuracy and higher torque than HOP series responding to demand from steel manufacturers. Compared with conventional Jet pipe mechanism, SST series with solenoid operated directional control valve can save running cost because of the structure which has less deterioration of operation oil and low maintenance work.
