EMA Valve Nachi Power Amplifier Series for Electro Hydraulic Proportional Valve Drive. This special amplifier is for driving electro hydraulic proportional pressure control valves.
Product Description :
This special amplifier is for driving electro hydraulic proportional pressure control valves, electro hydraulic proportional flow control valves and electro hydraulic proportional direction control valve. It comes in a choice of two different types : an amp type and a controller type.
Basically, the amp type converts 0 to 10V DC range command voltage to a DC current of in the range of 0 to 900mA, which is then supplied to then control valve. The control type performs multi stage control of output current in accordance with the ON-OFF signal of external contacts.
