Product Description
CSBF Series Manual Proportional Flow & Direction Compound Valves
Product Overview: The CSBF Series is a high-performance hydraulic proportional control valve that integrates dual functions: flow regulation and directional switching. Via a manual lever, users can achieve precise, stepless control over both the speed and direction of hydraulic actuators, such as motors or cylinders. This category highlights the core models: CSBF-G40 and CSBF-G50-M. The unique compound design simplifies system piping, enhances operational sensitivity, and improves overall system stability. It is the ideal control component for material handling equipment, drilling rigs, municipal vehicles, and various mobile machinery hydraulic systems.
Key Technical Advantages:
Integrated Compound Function: Combines proportional flow control and directional switching in a single valve body, reducing piping connections and the risk of system leakage.
Precise Proportional Adjustment: Precision-machined spools ensure the operating lever force is linearly proportional to the output flow, providing excellent control feel and “inching” performance.
Pressure Compensation: Features superior pressure-sensing characteristics, ensuring the output flow remains consistent regardless of load pressure fluctuations.
High Reliability & Contamination Resilience: Constructed with high-strength cast iron bodies and hardened spools, offering high tolerance to fluid contamination in harsh industrial environments.
Technical Spec Decoding:
CSBF: Proportional flow & direction compound valve series code.
G40 / G50: Nominal size/diameter (representing different rated flow ranges).
M: Denotes manual operation type and specific functional options.
Detailed Models & Parameters:
Core Series: CSBF Proportional Compound Valve.
Featured Model Matrix:
CSBF-G40: Standard nominal size for precise medium-flow control.
