History of Solenoid Operated Directional Valve, Size 1/8
The solenoid operated directional valve in 1/8 size (DSG-01) was first named Design 10 and authorized as a complete engineering release in 1966. Until the release of Design 70 in 2004, its major specifications were updated over 38 years, as … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
Yuken Manually Operated Directional Valves
These valves are manually operated to change the direction of hydraulic flow. They are available in the spool-operated and rotary types. These valves are structured in two types, detent and spring. The detent type maintains the spool position at the … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
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), … Continue reading
