OEM Factory Customized Pilot Operated with Electrical Position Feedback Hydraulic Proportional Directional 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. Ultra-Precise Closed-Loop Control:Electrical position feedback enables real-time monitoring and correction for unmatched accuracy in spool position, flow, and force/speed.
2. High Flow Capability (Pilot Operated):Controls large flows efficiently using minimal pilot pressure.
3. Enhanced Stability & Accuracy:Feedback ensures consistent performance under varying loads, critical for precision processes.
4. Optimized Efficiency:Precise control minimizes energy waste.
5. Seamless Integration:Custom-built to fit specific machine interfaces, plumbing, and control protocols.
6. Robust & Durable:Designed for exact operating conditions (pressure, fluid, environment).
7. Lower Total Cost (OEM Factory):Bulk savings via direct pricing; reduced downtime and energy costs.
