Custom OEM Dbetr Proportional Relief Valve Hydraulic 160 L/Min 21 Bar

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. Precision Control: Enables exact, variable pressure setting via proportional electrical signals.
2. Enhanced Efficiency:Optimizes system performance and energy consumption.
3. Robust Construction: Ensures reliable operation under demanding conditions.
4. Customization: Factory OEM tailoring for specific flow, pressure, voltage, or port requirements.
5. Cost-Effectiveness: Wholesale pricing and direct factory sourcing reduce acquisition costs.
6. System Integration:Simplifies design and improves overall hydraulic system responsiveness.
7. Durability: Engineered for long service life with quality materials.
