Nachi Electro-hydraulic control valve
Nachi Electro-hydraulic Proportional Valve Series
Built-in electronic components deliver outstanding response and fluid pressure that allows high output, as well as superior operation, and control.
The NACHI Electrohydraulic Proportional Valve Series includes the pressure control valves, flow control valves, and direction control valves that make it easy to meet these needs.
Nachi Electro-hydraulic Proportional Pilot Relief Valve
Nachi Electro-hydraulic Proportional Relief Valve
Throughput volume and fluid temperature fluctuation has little effect on control pressure, so
this valve provides open loop control of even
complex pressures (forces).
Nachi Electro-hydraulic Proportional Relief and Reducing Valve
This valve combines a compact, high-performance electro-hydraulic pilot relief valve, and a reducing and relief valve for low-pressure control of pressure within a hydraulic system in proportion to input current.
Since this valve includes a relief function, OUT side pressure can be maintained at a virtually fixed level, even when the valve’s OUT side is used as reaction force. This valve also provides outstanding response as pressure drops.
Nachi Electro-hydraulic Proportional Flow Control Valve
This valve controls actuator speed in response to the size of input current. Pressure and control fluid temperature fluctuation has little effect on setting pressure, which enables high-precision speed control. This valve is the perfect choice for actuator acceleration and deceleration control, and remote control.
Nachi Load Response Electro-hydraulic Proportional Relief and Flow Control Valve
The load sensing function of this meter in flow control valve makes it possible to control pump discharge pressure automatically in accordance with the size of the load pressure.
Using this valve suppresses wasteful pump pressure rises and makes it possible to configure an energy-efficient circuit.
Nachi Electro-hydraulic Proportional Flow and Direction Control Valve
This valve uses a DC solenoid in a traditional 4-way solenoid valve to create a solenoid valve capable of both direction switching and highspeed control. The lineup consists of the direct system 01 size and the pilot system 03, 04, and 06 sizes.
Direction control is performed by supplying input current to one of the two proportional solenoid valves, and the size of the flow rate is controlled in accordance with the size of the input current. This type of valve can be used for remote control and shockless acceleration and deceleration control, and for simple configuration of hydraulic circuits.
Nachi Modular Type Electro-hydraulic Proportional Reducing Valve
This valve incorporates the ease-ofuse principles of the modular valve into an electro-hydraulic proportional reducing valve to provide reduction control of hydraulic system pressure in proportion to input current.
This valve is perfect for a small-scale hydraulic system, such as those used for continuous proportional control of lathe chuck pressure. A relief function ensures outstanding pressure response characteristics.
