Yuken DSHG-10 Proportional Control Valve | DSHG-10-3C60-ET-A220-52T Solenoid Pilot Valve Replacement

Genlu Hydraulic proudly introduces our DSHG-10 Series (Nominal Size NG32 / 1-1/4″) high-performance solenoid pilot operated directional control valves. This series is engineered as a seamless, premium replacement for the classic Yuken DSHG large-flow valve platform. Designed to manage heavy-duty fluid directional flow within high-pressure and high-volume industrial systems, this valve utilizes a sub-miniature solenoid valve as its pilot stage to precisely control the hydraulic shifting of the main spool. Genlu guarantees 100% Drop-in Interchangeability in subplate mounting patterns (fully compliant with ISO 4401-10 standards), bolt fastening dimensions, pilot/drain oil routing configurations, and low pressure-drop characteristics compared to original Yuken units. Every DSHG-10 valve bank undergoes 100% simulation testing prior to shipment to ensure rapid spool responsiveness, zero binding, and exceptionally low internal leakage under demanding cyclic operations.

Technical Specifications 

• Product Series: Yuken DSHG Series Solenoid Pilot Operated Directional Valve

• Complete Configuration Model: DSHG-10-3C60-ET-A220-52T (Alternative designation: DSHG-10-3060-220)

• Nominal Size: NG32 (1-1/4 inches)

• Max Operating Pressure (Ports P, A, B): 31.5 MPa (315 bar)

• Max Flow Capacity: Up to 1100 L/min

• Spool Type Function: 3C60 (3-position 4-way, closed center position configuration)

• Pilot and Drain Style: ET (E: Internal Pilot / T: Internal Drain)

• Solenoid Coil Voltage: A220 (AC 220V, 50/60Hz)

• Wiring Connection Type: 52T (Standard terminal box enclosure model)

Key Technical Advantages:

• High-Volume & Low Pressure-Drop Channels: The main valve body features a fluid-dynamically optimized internal cast core, drastically minimizing pressure loss ($\Delta P$) when large flow rates bypass the valve ports, reducing fluid heat buildup and maximizing energy savings.

• High-Rigidity Compacted Graphite Iron Body: Forged from premium high-strength cast iron, the main housing withstands harsh pressure shocks. Even under continuous 31.5 MPa alternating loads, the core bore remains distortion-free, facilitating seamless spool movement.

• Shockless Hydraulic Pilot Dynamics: Outfitted with low-power consumption pilot solenoids, the shifting profile offers optimal decompression dampening. This mitigates severe hydraulic shock (water hammer effects) during high-flow switching, shielding piping elements.

• Micron-Matched Spool Clearances: The main spool and bore pair are precision ground to micronic tolerances and engineered with balancing grooves. This structure guarantees minimized internal volume leakage under full pressure and prevents hydraulic lockups during long inactive standby intervals.

Application Areas:

• Heavy Duty Hydraulic Machinery: Main directional circuits for heavy-duty metal scrap shears, scrap balers, and four-column forging presses.

• Iron & Steel Metallurgy: Large flow fluid distribution manifolds for rolling mill stations and auxiliary blast furnace hydraulic valve stands.

• Large Plastic & Rubber Machinery: High-flow clamping circuits for high-tonnage injection molding units and rubber vulcanizing machines.

Expert Maintenance Tips:

• Pilot/Drain Configuration Verification: The DSHG-10-3C60-ET is configured as internal pilot and internal drain (ET) by default. If your circuit architecture dictates external piloting or external draining, you must adjust the corresponding internal socket plug/steel ball before commissioning to avoid spool shifting failure.

• Minimum Pilot Pressure Requirement: Because the main spool shifts via pilot hydraulic forces, ensure that the minimum dynamic pressure at the pilot supply line stays above 1.0 MPa (10 bar). Dropping below this limit during low-pressure standby modes may cause shifting sluggishness.

• Electrical Enclosure Sealing: The 52T designation provides an integrated electrical junction box. During wiring, ensure the rubber gasket is correctly seated and the enclosure screws are fully tightened to block cutting fluids, moisture, or oil mist from entering the terminal sector.
