• 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/*
