Yuken Multiple Control Valves

These valves have multiple functions, including direction, relief, and check control in one body and are mainly used for vehicles. Whether the functions are to be activated individually or simultaneously determines the circuit type: parallel, tandem, or series. When the directional control function is not working, the pump output flow goes through the valve into […]

Yuken Pilot Operated Check Valves

These check valves have a pilot piston, which works with remote pressure to open the closed check valve, allowing reversed flow. Two types, standard and decompression, are available. The decompression type has a main poppet valve combined with a decompression valve. When the pilot pressure increases to lift the pilot piston, the decompression poppet valve […]

Yuken Check Valves

These valves allow free flow in one direction, while preventing flow in the reverse direction. They are used to prevent reversed flow, and two check valve types, in-line and right angle, are available. The poppet opens when the inlet pressure exceeds the spring force. The pressure at which the poppet starts to open is called […]

Yuken Pilot Operated Directional Valves

These valves perform spool changeover by the hydraulic pilot. They are useful when the pilot directional control valve and the main directional control valve should be installed distant to each other. The pilot pressure for spool operation is 0.5 MPa (72.5 psi) at minimum. Figure 4.8 shows the pilot operated directional valve (DHG-06).

Yuken Shut-off Type Solenoid Operated Directional Valves (Poppet Type Two-Way Solenoid Operated Directional Valves)

These valves are solenoid-operated two-way directional valves that operate a poppet valve by the solenoid to open/ close hydraulic passages. Two types of them are available: cartridge and sub-plate mounting. Because they are the poppet type, the internal leakage is almost zero. Figure 4.7 shows the shut-off type solenoid operated directional valve (DSPG-01).

Yuken Poppet Type Solenoid Controlled Pilot Operated Directional Control Valves

These valves are solenoid controlled pilot operated directional valves, which are made multi-functionable by granting individual poppet functions, such as directional control, flow control, and pressure control. They consist of a main valve with four poppets, a solenoid operated directional valve for the pilot line, and a pilot selector valve. These valves are used in […]

Yuken Solenoid Controlled Pilot Operated Directional Valves

These valves are a combination of a small solenoid operated directional valve and a large pilot operated directional valve. The small four-way solenoid valve is used for directional control of the pilot line. The main valve (main spool) provides directional control of the main line. The pilot operated directional valve includes the spring offset, spring-centered […]

Yuken Solenoid Operated Directional Valves

These valves control the flow direction in hydraulic circuits, electrically operated with manual switches, limit switches, or pressure switches. They are the most popular for use in practical hydraulic systems. Three types of solenoids are available: for direct current (DC), for alternating current (AC), and with a rectifier. The solenoids can be grouped into wet […]
