The SUN DPCN-LAN, DPCN-LBN, DPCN-LDN, DPCN-LEN, DPCN-LWN are high-performance pilot operated pressure relief valves engineered by Sun Hydraulics, designed to deliver precise pressure regulation and robust overpressure protection for hydraulic systems. As cartridge-style components, these valves fit the industry-standard T-23A cavity, enabling seamless drop-in installation without modifying existing manifolds. Ideal for low, medium, and high-pressure applications across industrial manufacturing, mobile machinery, marine operations, and oil & gas sectors, the DPCN series combines low hysteresis, stable performance, and long-term durability.

Advanced Pilot-Operated RegulationThe DPCN series uses a dedicated pilot valve to control the main piston, ensuring ultra-accurate pressure setting with ≤3% typical hysteresis and minimal pressure drift. Its flat pressure-flow curve maintains consistent system pressure even under fluctuating flow, reducing energy waste and extending downstream component life. The integrated pilot port supports remote pressure adjustment, compatible with automated PLC systems for enhanced safety and efficiency.

Model-Tailored Performance
DPCN-LAN: Optimized for low-pressure circuits, with fast response for light-duty industrial equipment and auxiliary systems.
DPCN-LBN: Balanced piston design minimizes pressure fluctuations in medium-pressure applications (e.g., construction/material handling machinery).
DPCN-LDN: Rugged build for high-pressure environments (up to 5000 psi), ideal for hydraulic presses, mining equipment, and wellhead controls.
DPCN-LEN: Ultra-low hysteresis for precision-focused systems (e.g., automated production lines, CNC machines).
DPCN-LWN: Externally drained pilot configuration eliminates backpressure interference, perfect for complex multi-circuit setups (marine/offshore systems).
Easy Integration & Durability
All models fit the T-23A cavity for drop-in installation/replacement, cutting maintenance time and costs. Made with high-grade alloys, they resist wear/corrosion and perform reliably in -20°C to +100°C temperatures, even in high-vibration/dusty environments.
Construction/Mining: Excavators, loaders, mining trucks (overpressure protection in rough terrain).
Industrial Manufacturing: Injection molding, metal forming, CNC presses (precision pressure control).
Marine/Offshore: Ship steering, winches, offshore platforms (corrosion-resistant, stable performance).
Agriculture: Tractors, harvesters (reliable regulation in high-dust environments).
Oil & Gas: Wellhead panels, pipelines (safe high-pressure operation).
Sun Hydraulics Quality: Rigorously tested to global standards, backed by decades of hydraulic expertise.
Cost-Effective: Drop-in design reduces installation/maintenance costs and downtime.
Versatility: Covers all pressure ranges, eliminating the need for multiple valve types.
Longevity: Corrosion-resistant materials lower total ownership cost.
