ATOS Construction Machinery Hydraulic Solenoid & Proportional Valves

● ATOS Construction Machinery Valves Technical Support

● ATOS electrohydraulic solenoid directional valves and electrohydraulic proportional valves are widely utilized across high-demand construction machinery and mobile hydraulic equipment.

● Engineered for harsh operating environments, ATOS solenoid valves (including DHI/DHE direct-operated directional valves, DKE heavy-duty spool valves, DPZO electrohydraulic proportional valves, DLHZO servo-proportional valves with LVDT feedback, and DLOH leak-free poppet valves) operate at working pressures up to 350 bar. Mounted directly on mobile machine main control blocks, pilot manifolds, and auxiliary function interfaces, they provide millisecond-fast response, ultra-low internal leakage, and precise electrohydraulic flow and pressure metering for excavators, mobile cranes, rotary drilling rigs, and concrete pump trucks.

● Ensure proper electrical connector seal IP rating (IP65/IP67), maintain oil cleanliness per ISO 4406 standards, and verify pilot supply pressures during scheduled maintenance.

● ATOS Construction Machinery Valves Specifications

Compatibility note: Applicable to rotary drilling rigs, hydraulic excavators, mobile all-terrain cranes, concrete boom pumps, shield tunneling machines, and heavy road headers. Please verify valve spool configuration, voltage (12VDC / 24VDC), and connector type prior to ordering.
