Services: We offer disassembly, rotating group replacement, port and valve block repair, shaft balancing, and full high-pressure testing.
Linde / LHY Hydraulic Valves & Control Systems
HFI supplies and services high-pressure hydraulic valves from Linde Hydraulics / LHY Powertrain, including both VT Modular and Monoblock valve systems. These advanced control valves are widely used in load-sensing hydraulic systems for mobile machinery operating in open-loop circuits.
- VT Modular: Modular main control valve system for load sensing open-loop circuits, available in nominal sizes 18, 25, and 30. Up to eight sections can be configured in a single manifold block for complex actuator control.
- Monoblock: Compact high-pressure valve solution with integrated input/output in one cast housing. Available in sizes 18, 25, and 30, ideal for mobile machines with limited installation space.
- Linde Synchron Control (LSC): An intelligent control system that translates driver input into hydraulic motion via post-compensated flow control valves – offering smooth, coordinated actuator movement.
Applications: Load-sensing control for excavators, telehandlers, forestry equipment, road pavers, agricultural machinery, and more.
Services: We provide valve cleaning, spool reconditioning, leak testing, solenoid and actuator replacement, and calibration of LSC-controlled functions.
