Product Overview of I-65B Check Valve
The I-65B check valve is a crucial component in hydraulic systems, designed to prevent reverse flow of oil and maintain system pressure stability. Available in straight-through or right-angle configurations, it offers flexible installation options including threaded, plate-mounted or flanged connections. The valve features a precision-engineered cone-shaped core that ensures reliable sealing performance, with minimal pressure loss during operation. Manufactured from high-strength alloy steel or cast iron through advanced machining processes, it undergoes rigorous pressure testing for durability. This product is widely applied in hydraulic pipelines for metallurgical, mining and construction equipment industries.14
技术特点与优势
I-65B单向阀具有结构紧凑、响应速度快的特点，阀芯动作灵敏且冲击小。其特殊设计的弹簧系统可确保在无压力状态下自动闭锁，反向密封压力可达系统工作压力的95%以上。产品重量经过优化设计，便于安装维护，同时采用模块化结构便于与其他液压阀组（如节流阀、顺序阀）组合使用。耐油橡胶密封件能适应-20℃至100℃的工作温度范围，长期使用不易老化。41625
Technical Features
The I-65B features a compact design with rapid response characteristics, where the valve core moves sensitively with minimal hydraulic shock. Its specially calibrated spring system guarantees automatic locking at zero pressure condition, achieving over 95% of system pressure in reverse sealing. The weight-optimized design facilitates installation and maintenance, while modular construction allows easy integration with other hydraulic valves like throttle valves and sequence valves. Oil-resistant rubber seals maintain stable performance within -20℃ to 100℃ operating temperature range, demonstrating excellent anti-aging properties.1621
应用场景说明
该产品适用于需要单向截流的液压回路，常见于工程机械的支腿锁紧系统、起重机的液压支路以及注塑机的保压回路。在空压机与气罐连接管路中能有效防止压缩空气回流，在变速器液压系统中可减少换档冲击。其耐高压特性使其在31.5MPa工作压力下仍能保持稳定性能，特殊工况下可与液控装置配合实现双向油路控制。1415
Application Scenarios
This valve is ideal for hydraulic circuits requiring unidirectional flow control, typically deployed in outrigger locking systems of construction machinery, hydraulic branches of cranes, and pressure-maintaining circuits of injection molding machines. When installed between air compressors and tanks, it effectively prevents compressed air backflow. In transmission hydraulic systems, it significantly reduces gearshift impacts. Withstanding working pressures up to 31.5MPa, it maintains stable performance and can be combined with hydraulic control devices for bidirectional flow management in special applications.425
产品可靠性说明
经过严格的质量验证流程，I-65B单向阀在模拟工况下完成超过百万次启闭测试，关键部件采用耐磨合金材料延长使用寿命。产品出厂前均进行72小时连续压力保持测试，确保无渗漏现象。针对不同介质特性可提供多种密封材料选项，满足矿物油、水-乙二醇等各类液压油的使用要求。616
Reliability Assurance
The I-65B undergoes rigorous quality verification including over one million cycle tests under simulated working conditions. Wear-resistant alloy materials are applied to critical components for extended service life. All products must pass 72-hour continuous pressure retention tests before shipment to guarantee leak-proof performance. Multiple seal material options are available to accommodate various hydraulic fluids including mineral oil and water-glycol mixtures.621
