Nachi Electro- Hydraulic Control Valve
The following are variations in product types from Nachi Electro – Hydraulic Control Valve :
Specifications
- Flow : 150 to 320 L/min
- Pressure : 0.3 – 35 MPa
Description
Electro-hydraulic Proportional Relief Valve
ER Series
This valve combines a compact, high-performance electro-hydraulic proportional pilot relief valve and balanced piston type relief valve to provide pressure control in proportion to input current.
Throughput volume and oil temperature fluctuation has little effect on control pressure, so this valve provides open loop control of even complex pressures (forces).
Specifications
- Flow : 1.2 L/min
- Max. Pressure : 0.3 – 35 MPa
Description
Electro-hydraulic Proportional Pilot Relief Valve
EPR Series
This DC solenoid relief valve matches the suction force of a DC solenoid withfluid pressure. When connected to a small-volume hydraulic system or the poppet of a balanced piston type pressure control valve, this valve provides continual pressure control in proportion to input current.
Specifications
- Flow : 50 – 100 L/min
- Max. Pressure : 0.3 – 25 MPa
Description
Electro-hydraulic Proportional Relief and Reducing Valve
EGB Series
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.
Specifications
- Flow : 0.5 to 500 L/min
- Pressure : 21 MPa
Description
Electro-hydraulic Proportional Flow Control Valve
(C)ES Series
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.
Specifications
- Flow : 1 to 500 L/min
- Pressure : 25 MPa
Description
Load Response Electro-hydraulic Proportional Relief and Flow Control Valve
ESR Series
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.
Specifications
- Flow : 10 to 250 L/min
- Max. Pressure: 25 MPa
Description
Electro-hydraulic Proportional Flow and Directional Control Valve
ESD Series
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.
Specifications
- Flow : 30 L/min
- Max. Pressure: 0.3 – 14 MPa
Description
Modular Type Electro-hydraulic Proportional Reducing Valve
EOG Series
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.
