OEM Factory Custom Hydraulic Proportional Pressure Relief Valve

Premium Quality Hydraulic Cylinders - Quality Assured

1. Internals:Cylinder barrel adopts GUOYUE EU/US metallurgical standard CD250 structure. Barrel material: 45#, 42CrMo, or 27SiMn. Bore honed to H8 precision with surface roughness Ra<0.4μm. Heads, base, trunnions, and pistons are exclusively made of 45# steel; no cast iron or cast steel components are used.
2. Buffering:Multiple buffering options including fixed and floating buffer structures to ensure effective deceleration across various pressures and speed ranges.
3. Welding:100% ultrasonic impact treatment applied to all pressure-bearing and load-critical welds. This eliminates weld stress (removal rate ≥90%) and significantly enhances weld fatigue strength.
4. Sealing:All cylinders exclusively use premium imported seals from Japan NOK, Sweden Trelleborg, Germany Merkel, and GP. No domestic seals are utilized.
5. Testing &Certification:Factory testing strictly complies with GB/T15622-2005 "Hydraulic Fluid Power - Test Methods for Cylinders" and internal premium standard Q/GAKY014-2023. Includes provision of factory test reports and product qualification certificates.
6. Warranty: One-year warranty from shipment date. Free repair or replacement provided for defects arising from design or manufacturing within the warranty period. Advantages:1.Cost Efficiency: Wholesale factory pricing reduces procurement costs significantly.
2.Precise Electronic Control:Enables stepless, dynamic pressure adjustment for optimal system response and process accuracy.
3.Energy Savings:Reduces system pressure losses, lowering power consumption and heat generation.
Custom Integration:OEM tailoring ensures perfect fit, porting, electrical interfaces, and performance specs for your machinery.
4.High Reliability:Robust construction withstands industrial environments, contamination, and pressure spikes.
Reduced Noise/Vibration:Smooth proportional operation minimizes system shock and noise. Advantages:1.Cost Savings:Direct factory wholesale pricing significantly reduces procurement costs.
2.Precision Control:Enables stepless, dynamic pressure adjustment for optimized system performance.
