The QSF32 series represents a versatile load-sensing proportional control solution, engineered for machines requiring precise speed control and simultaneous operation of multiple functions regardless of load variations. Key features include: 1. Advanced Load Sensing Technology: Optimizes energy consumption and reduces heat generation by supplying only the required flow and pressure. 2. High Flow Capacity: Supports up to 250 L/min, making it ideal for large-scale machinery like loaders and excavators. 3. Robust Sectional Design: The 163-section structure allows for modular flexibility and easier maintenance. 4. Extreme Adaptability: Performs reliably in harsh environments with an operating temperature range of -40°C to +80°C and a wide viscosity tolerance. 5. Universal Porting: Available with multiple port sizes including G1, SAE 16, and M36×2 to suit global plumbing standards. It is perfectly suited for complex maneuvers in construction, agriculture, and material handling equipment, ensuring smooth and accurate movement for boom pumps, cranes, and heavy-duty harvesters.
