? Pilot valve to restrict system pressure (control oil internal only)
? Can adjust by controlling the coil current according to the characteristic curve and the selected electronic control unit
? Solenoid type Imax=0.8 A or 2.5 A
? In the event of electronic control unit failure, the overload protection can function to the highest degree (coil current > Imax)
? Used in valve sub-plate mounting, installation hole follows ISO 441-03-02-0-94，
? Cable sockets follows DIN 43650-AM2
? External electronic control unit with ramp and valve adjustment function VT-SSPA1-508/525-L2X/V0/*
