单向阀，I-25B 价格
产品概述
单向阀I-25B是一款用于液压系统的高效流体控制元件，专为阻止油流反向通过而设计，广泛应用于工业设备、工程机械等领域。其采用精密结构设计，确保单向密封性能稳定，能有效降低压力损失，提升系统运行效率。该产品支持管式和板式两种安装方式，适配不同工况需求，材质坚固耐用，适合中低压液压环境。
English Introduction:
The I-25B check valve is a high-performance fluid control component designed for hydraulic systems, specifically to prevent reverse flow of oil. Widely used in industrial machinery and engineering equipment, it features a precision-engineered structure that ensures reliable one-way sealing with minimal pressure loss, enhancing system efficiency. Available in threaded (pipe) and plate mounting options, it adapts to diverse working conditions. The robust construction makes it ideal for medium-to-low pressure hydraulic applications. 11214
核心功能
单向阀I-25B通过弹簧加载的阀芯实现自动启闭功能，在正向油流时开启，反向时自动闭合，确保流体单向流通。其内部采用锥阀或钢珠密封结构，经过配研工艺处理，显著减少泄漏风险。产品工作压力为6.3MPa，流量25L/min，压力损失仅0.25MPa，兼具轻量化（0.6kg）与紧凑尺寸（管式螺纹接口Z3/8"），便于集成到复杂管路系统中。
English Introduction:
The I-25B utilizes a spring-loaded spool mechanism to automatically open under forward flow and close against reverse flow, ensuring unidirectional fluid passage. Its internal cone or ball sealing structure is precision-lapped to minimize leakage. With an operating pressure of 6.3MPa, flow capacity of 25L/min, and pressure drop of 0.25MPa, the valve balances lightweight (0.6kg) and compact design (Z3/8" threaded port) for easy integration into complex piping systems. 111218
应用场景
适用于注塑机、压铸机、机床等设备的液压回路，尤其在需要防止油液倒流的泵出口或执行元件回油管路中表现优异。其耐油性材质可兼容矿物油、合成油等多种介质，长期使用稳定性高。此外，模块化设计支持快速维护，降低停机时间。
English Introduction:
Ideal for hydraulic circuits in injection molding machines, die-casting equipment, and machine tools, the I-25B excels in pump outlets or actuator return lines where backflow prevention is critical. Compatible with mineral and synthetic oils, its oil-resistant materials ensure long-term stability. The modular design facilitates quick maintenance, reducing downtime. 11425
