Product Description
product name
YUKEN MPA-04-4-10Y Hydraulic Pressure Relief Valve
1. Product Overview
| The YUKEN MPA-04-4-10Y is a high-performance hydraulic pressure relief valve designed to protect industrial automation systems from overpressure damage. Part of YUKEN’s modular 04 series, this valve maintains system pressure within safe limits by diverting excess fluid to the reservoir when pre-set pressure thresholds are exceeded. With a maximum operating pressure of 31.5 MPa (4,570 psi) and flow capacity up to 100 L/min (26.4 gal/min), it suits applications such as presses, injection molding machines, and hydraulic power units. The CETOP D07 mounting interface ensures compatibility with standard manifolds, while its adjustable spring-loaded design allows precise pressure regulation. |
2. Technical Specifications
Type: | Direct-acting pressure relief valve |
Pressure Range: | 0.5–31.5 MPa (72.5–4,570 psi) |
Flow Capacity: | 100 L/min (26.4 gal/min) |
Mounting: | CETOP D07 (ISO 4401-07-4-A) |
Port Size: | G1/2" (BSPP) inlet/outlet |
Adjustment: | Knob-controlled spring compression (clockwise to increase pressure) |
Material: | Cast iron body with nitrided steel components |
Temperature Range: | -15°C to +70°C (-5°F to +158°F) |
Certifications: | CE compliant (ISO 9001 pending) |
3. Design Features
| The MPA-04-4-10Y features a direct-acting piston design for fast response times (<10 ms) and stable pressure control. Its self-draining pilot system prevents fluid stagnation, while the double-sealed poppet valve ensures zero leakage at rated pressure. The threaded adjustment knob allows for incremental pressure setting, and a locking nut secures adjustments to prevent accidental changes. For noise reduction, an optional silencing kit (sold separately) reduces cavitation during operation. |
4. Applications
Industrial Machinery: | Presses, injection molding machines, and hydraulic lifts. |
Mobile Hydraulics: | Construction equipment (e.g., excavators, cranes) and agricultural machinery. |
Process Automation: | Chemical reactors, mixers, and pumps requiring overpressure protection. |
Energy Sector: | Wind turbines, generators, and hydraulic power packs. |
Aerospace: | Ground support equipment and test benches. |
5. Installation & Compatibility
| Installed via the CETOP D07 interface, the MPA-04-4-10Y integrates seamlessly with standard subplates and modular valve stacks. It works with mineral oil-based hydraulic fluids (ISO VG 32–46) and is compatible with YUKEN’s proportional control modules for automated pressure regulation. For extreme environments, optional high-temperature seals (up to +120°C) are available. |
6. Maintenance & Longevity
| Routine maintenance involves checking for leaks, verifying pressure settings, and inspecting O-rings for wear. The modular design allows easy replacement of internal components (e.g., poppet, spring) without disassembling the entire system. With proper fluid filtration (NAS 1638 class 12 or better), the valve delivers 15,000+ hours of continuous operation in typical industrial settings. |
7. Unique Advantages
Precision Control: | ±1.5% pressure stability across the entire flow range. |
Fast Response: | Direct-acting design minimizes system overshoot. |
Space-Saving: | Modular stacking reduces installation footprint by 30%. |
Cost-Effective: | Single-unit solution eliminates need for auxiliary components. |
Durability: | Nitrided steel components resist corrosion and wear. |
