Sun Hydraulics RPEC, RVGA & XNCA Series Pressure Control Cartridges

Product Overview: Sun Hydraulics Cartridge Valves are globally recognized for their superior reliability and unique “Floating Style” design. This category highlights precision pressure management models: RPEC-LEN (RPECLEN) Pilot-operated Relief Valve, RVGA-LCN (RVGALCN) Ventable Relief Valve, and XNCA-XXN (XNCAXXN) Logic Cartridge.

Engineered for precision control under high-pressure and high-flow conditions, these screw-in cartridges integrate seamlessly into custom manifolds. They are the premier choice for industrial presses, primary control valves in construction machinery, machine tool fixtures, and mobile hydraulic power units.

Key Technical Advantages:

• Floating Construction: Allows internal components to self-center during installation, preventing spool binding caused by manifold machining tolerances and extending service life.

• Superior Regulation Linearity: The pilot-operated architecture (e.g., RPEC Series) maintains a consistent set-pressure across varying flow rates with minimal hysteresis.

• Extreme Durability & Sealing: Hardened and precision-ground internal working parts ensure high repeatability and performance under continuous 350 Bar cycles.

• Series Precision Matrix:

  • RPEC Series: Classic two-stage pilot-operated relief valves, ideal for main system protection or remote pressure control.

  • RVGA Series: Specialized ventable relief design for circuits requiring precise pressure-differential adjustments.

  • XNCA Series: Logic element cartridges utilized for building complex integrated pressure or flow control logic.
