MBRV-02P Stacked One-way Throttle Valve Product Introduction
Product Overview:
The MBRV-02P Stacked One-way Throttle Valve is a hydraulic flow control component featuring a unidirectional flow design with integrated valve structure. This product enables precise adjustment of working medium flow during single-direction movement in hydraulic circuits. Suitable for industrial equipment and construction machinery requiring accurate motion control of actuators, its optimized flow path design and material selection ensure reliable performance while simplifying system installation.
Structural Features:
The valve body is precision-machined from high-strength alloy material, integrating a check valve core and throttling mechanism. The rotary adjustment handle allows stepless speed regulation within 0-5mm/s range. The stacked configuration complies with ISO 4401 mounting standards, enabling direct integration with directional valves or hydraulic valve groups to minimize pipeline connections. Corrosion-resistant surface treatment ensures stable operation in ambient temperatures ranging from -20℃ to 80℃.
Performance Advantages:
Fluid dynamic optimization delivers linear flow characteristics within the adjustable range, maintaining pressure fluctuation within ±0.2MPa. Bidirectional sealing structure achieves zero leakage during reverse closure, with activation response time under 0.3 seconds. Specially designed damping mechanism effectively reduces hydraulic shock, while wear-resistant valve core material ensures over 5,000 hours of continuous service at rated 21MPa pressure. The visible calibration ring on the adjustment mechanism enables quick flow parameter setting.
Application Scenarios:
Ideal for injection molding machine clamping speed control, machine tool feed system regulation, and hydraulic cylinder buffering in metallurgical equipment. In construction machinery applications, it precisely controls crane arm extension speed and excavator bucket movement. Compatible with various hydraulic power units, this valve meets diverse industry demands for smooth actuator motion and operational accuracy.
