40Ω – 10Ω Series Flow Control and Relief Valves (EFBG-03/06/10-17)
This flow control and relief valve is an energy-saving valve that supplies the minimum pressure and flow necessary for actuator drive. Since this valve controls the pump pressure by following the load pressure while keeping the differential pressure minimized, it serves as a low power consumption energy – saving, meter-in, controlled flow control valve. Further, since a temperature compensation function is incorporated, this valve provides consistent flow control without respect to the fluid temperature.
High Response Directional and Flow Controls
High Response Type Proportional Electro-Hydraulic Directional and Flow Control Valves
High response, high precision and high reliability are achieved be a combination of a compact and powerful solenoid and a spool-position-detection LVDT. Direct type ELDFG-01/03 and two stage type ELDFG-04/06 (which use the ELDFG-01 as a pilot) are available.
Direct Operated Type Directional and Flow Control Valves
This product can be interchanged with the simplified servo valve to perform position control and pressure control. Compared to nozzle flapper type servo valve, this product has excellent contamination-related problems
EBG Proportional Relief Valves
This valve is derived by combining a small, high-performance 1/8 proportional electro-hydraulic pilot relief valve with a specially developed low-noise relief valve. With this valve, it is possible to regulate the system pressure in proportion to the input current. Note that this valve is used in conjunction with the applicable power amplifier.
ELDFG High Speed Proportional Directional & Flow Control with On Board Electronics
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).
High Response Directional and Flow Controls (EHDFG)
These valves pursue the ultimate performance of proportional electrohydraulic directional & flow control valves and make themselves to have high response features. The closed-loop is composed in the valve inside by combination of a differential transformer (LVDT) and a power amplifier. Thus, high accuracy and reliability are provided. In addition to control in the open-loop, these can be used for the closed loop system as simplified servo valves.
Proportional Flow Control and Check Valves (EHF(C) G-03/06)
The system flow rate can be controlled remotely as desired by regulating input voltage. Further, since pressure and temperature compensation functions are provided, the preselected flow rate is not affected by pressure (load) or temperature (fluid viscosity).
Proportional Pressure Control Valves (SB1110 SB1190)
These are closed-loop type pressure control valves controlling the system pressure from low too high in proportion to the input voltage. The stable pressure control is possible even in a small flow rate.
Proportional Relieving and Reducing Valves (EHRBG)
These valves consist of a small size but high performance electro-hydraulic proportional pilot relief valve and reducing valve with relief function. The valves control the system pressure proportionally through a controlled input voltage. Moreover, a good response speed in reducing the pressure even at a large load capacity can be obtained with the relief function of the valves.
EDG Pilot Relief Valves
This valve consists of a small DC solenoid and a direct-acting relief valve. It serves as a pilot valve for a low flow rate hydraulic system or a proportional electro-hydraulic control valve and controls the pressure in proportion to the input current. Note that this valve is used in conjunction with the applicable power amplifier.
