Closed loop, high response type proportional electro-hydraulic directional and flow control valves with on board electronics. Two direct type models with a maximum rated flow rate up to 80 l/min (@.ΔP=1MPa) are available. Two different available models of two stage OBE valves have a maximum rated flow rate up to 500 L/min (ΔP=0.5MPa (72 psi) at each port).
