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.
EH Pilot Relief Valves (EHDG-01)
The valve can be used as a pilot valve of the Proportional Electro- Hydraulic Control Valves. The valve can also be used as a relief valve for the hydraulic system where a small flow rate and continuous pressure control are required.
EHDFG 01/03 Proportional Directional and Flow Control Valves
These valves incorporate two control functions – flow and direction – which simplify the hydraulic circuit composition and therefore the cost of the system is reduced.
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 Flow – Flow Control and Relief Valves (EFBG-03-250/06-500/10-1000-51)
This flow control and relief valve is an energy-saving valve that supplies the minimum pressure and flow necessary for actuator drive. For the High Flow Series, double maximum flow rate [03 size: 125→250 L/min (33.03→66.05 U.S.GPM), 06 size: 250→500 L/min (66.05→132.1 U.S.GPM), 10 size: 500→1000 L/min (132.1→264.2 U.S.GPM)] enables a smaller valve size than conventional products; compact-sized devices can be provided.
High Flow-Flow Control and Relief Valves (EHFBG-03-250. EHFBG-06-500)
This flow control and relief valve is a energy-saving valve that supplies the minimum pressure and flow necessary for actuator drive. For the High Flow Series, double maximum flow rate [03 size: 125 → 250 L/min (33 → 66 U.S.GPM), 06 size: 250 → 500 L/min (66 → 132 U.S.GPM)] enables a smaller valve size than conventional products; compact-sized devices can be provided.
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.
High Response Directional and Flow Controls (ELDFG 01/03)
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.
