LT-4TH6E (Pilot Pressure Reducing Valves)
The LT-4TH6E pilot pressure reducing joystick valves are used for pilot pressure regulation in hydraulically piloted control systems. By reducing and stabilizing system pressure, they provide a reliable pilot pressure supply for hydraulic pilot joystick valves and main multi spool directional control valves. The joystick valve is applicable to hydraulic control systems of excavators, loaders, bulldozers, cranes, and other construction machinery, ensuring consistent control response of pilot circuits under varying operating conditions.
Features & Advantages
- Stable pilot pressure output: Provides a controllable and stable pressure supply for pilot control systems, improving consistency and repeatability of operation.
- Suitable for system integration: Compact structure allows easy integration into pilot circuits or valve manifolds.
- Wide applicability in pilot-controlled systems: Compatible with hydraulic pilot joystick valves and hydraulically piloted multi spool directional control valves.
