FUNCTION: This is an ideal hydraulic proportional remote control system when max. movement precision and long- lasting reliability are required. The system needs a secondary circuit with low pressure pilotage, fed separately by a dedicated pump and in derivation to the primary one. In this last case, it is necessary to include a feeding unit with eventual accumulator for emergency interventions into the circuit. 1) Inlet port(P) where oil be fed from pilot pump or Feed unit. 2) Out port (1,2,3,4) be supplied oil from inlet port and send to main valve control kits, 3) T port connect to oil tank.
