The
YUKEN 005 Series Modular Valves are
mini-series stacked hydraulic valves developed by
Yuken Kogyo Co., Ltd., adopting the
D02 (ISO 4401-02-01-0-94) mounting surface standard. They form hydraulic circuits through stacking, eliminating the need for complex pipeline connections.
I. Core Features
-
Compact Design: Smaller than the standard 01 series, saving installation space.
-
Pipeline-Free Connection: Stacked installation reduces oil leakage, vibration and noise issues, improving system reliability.
-
High Integration: Various functional modules can be freely combined to quickly build complex hydraulic circuits.
-
Easy Maintenance: The modular structure facilitates inspection and replacement of individual valve components.
-
Wet Solenoid: Used in solenoid directional valves to achieve durability and low noise.
-
High Pressure Performance: Maximum working pressure up to 25 MPa (250 Bar, 3630 PSI), maximum flow rate 15 L/min (3.96 U.S.GPM).

IV. Typical Application Fields
-
Machine Tool Equipment: Hydraulic system control of CNC machine tools and machining centers.
-
Injection Molding Machinery: Precisely controls injection pressure and flow rate to ensure molding quality.
-
Automated Production Lines: Direction, speed and pressure control of executive components.
-
Metallurgical Equipment: Hydraulic systems operating under high temperature and high pressure conditions.
-
Small Construction Machinery: Hydraulic systems with limited space.
-
Medical Equipment: Hydraulic applications requiring high-precision control.
V. Installation and Maintenance Points
-
Before Installation:
-
Clean hydraulic oil and pipelines to prevent impurities from entering the valve body.
-
Check the condition of seals to ensure no damage.
-
Confirm that the mounting surface is flat, free of scratches or burrs.
-
During Installation:
-
Stack valves in the order of the hydraulic principle diagram, paying attention to the direction of oil ports.
-
Tighten bolts evenly to avoid valve body deformation.
-
For solenoid directional valves, pay attention to electrical connections and solenoid direction.
-
Maintenance:
-
Regularly check system pressure and flow rate to ensure normal operation.
-
When adjusting pressure, first loosen the lock nut, then retighten it after adjustment.
-
If oil leakage or abnormal noise is found, promptly check seals and internal valve components.
VI. Comparison with 007 Series
The
YUKEN 005 Series and 007 Series are both mini-series stacked valves, with the main differences being:
-
005 Series: Maximum flow rate 15 L/min, suitable for small hydraulic systems.
-
007 Series: Maximum flow rate 25 L/min, suitable for systems with medium flow requirements.
Both adopt the same mounting surface standard and can be mixed in the same hydraulic circuit to meet different flow requirements.
With its compact design, high reliability and flexible combination characteristics, the YUKEN 005 Series Modular Valves have become an ideal choice for modern hydraulic system design, especially suitable for application scenarios with limited space and precise control requirements.
