SUN Hydraulics RPCC-LCN | CXJA-XCN | CXKA-XCN | Threaded Pressure Reducing Valve

RPCC & CXJA Series Threaded Pressure Reducing & Check Valves

Product Overview:

This series of precision Threaded Cartridge Valves serves as the backbone of hydraulic manifold design. The RPCC-LCN is a pilot-operated pressure reducing valve that ensures stable, adjustable secondary pressure for downstream circuits, even amidst significant primary system pressure fluctuations. When paired with the CXJA and CXKA series check valves, it facilitates efficient unidirectional flow control and pressure isolation. Manufactured from high-strength alloy steel, these valves offer high response frequencies and superior sealing, making them ideal for injection molding, machine tools, and mobile machinery.

Featured models include: RPCC-LCN, CXJA-XCN, CXJA-LCN, CXJA-XAN, CXJA-XBN, and CXKA-XCN.

Key Technical Advantages:

• Stable Precision Reduction: The RPCC series provides excellent regulation linearity, maintaining precise branch circuit pressure to protect actuators from overload.

• Low Pressure Drop Check Function: CXJA and CXKA check valves feature optimized flow paths for minimal pressure drop at high flow rates, enhancing overall system energy efficiency.

• All-Steel Wear-Resistant Construction: Hardened and ground internal components guarantee outstanding repeatability and zero-leakage performance over millions of cycles.

• Standard Cavity Compatibility: Fits standard T-11A and T-13A SUN-style cavities, enabling rapid installation, replacement, or system upgrades.
