The KLS KLS-HSD-T2A is a premium, custom-engineered hydraulic control valve manifold block designed specifically for marine provision crane winch motor control. Engineered to meet the rigorous demands of maritime environments, this non-standard valve assembly is specifically tailored for TTS shipboard crane hydraulic systems with a 4T load rating. The manifold block seamlessly integrates high-performance cartridge valves, including a CAEA-LHN counterbalance valve for reliable load holding and an RD-08W-11 relief valve cartridge for precise pressure regulation. To facilitate easy installation, diagnostics, and maintenance, the block features clearly marked ports (A, B, L, R, M1, M2), built-in pressure test ports, quick-connect couplings, and plugged service ports. It is an essential component for ensuring safe, efficient, and smooth crane lifting operations at sea.
