Sun Hydraulics ECC OHK5-AA Hydraulic Valve Block

Sun Hydraulics ECC OHK5-AA Hydraulic Valve Block is a compact, line-mount manifold from Sun’s ECC family designed to host and interconnect cartridge valves for precise hydraulic control. As part of the ECC line, the OHK5-AA block emphasizes efficient integration in fluid-power systems, enabling designers to assemble multi-valve circuits on a single modular block for tight installation envelopes in industrial automation, machine tools, and other hydraulics-driven equipment. The ECC family is built to work with Sun’s cartridge valves, offering a compact footprint and clean, field-attachable plumbing that supports quick-design workflows with Sun’s design tools. The OHK5-AA designation identifies a particular variant within the ECC family, suitable for applications where a compact valve-block solution is preferred to simplify piping, improve response times, and reduce installation time. Typical use cases include centralized control of actuators, proportional or dedicated relief/sequence circuits, and other electro-hydraulic control schemes where space constraints exist and fast valve actuation is required.
