天榆液压气动MPCV-02B/MPCV02B
产品概述
MPCV-02B/MPCV02B是天榆液压气动有限公司生产的一款叠加式液控单向阀，主要用于液压系统中控制油液的单向流动，同时可通过外部压力油实现反向开启。该产品采用铸铁材质，具有结构紧凑、安装便捷的特点，适用于各类液压机械、冲床及五金机械设备，能够有效稳定系统压力并保障液压回路的可靠运行。1219
功能特点
MPCV-02B/MPCV02B通过液控设计实现双向油路控制，在常规状态下允许油液单向通过，当需要反向流动时，通过外部控制油压推动阀芯开启。产品工作压力可达24MPa，适用于中高压液压系统，且对油液黏度适应范围广（15-400cSt），兼容石油基油、合成液及水-乙二醇等介质。其叠加式结构便于与其他液压阀组集成，减少管路连接，提升系统整体稳定性。2628
技术参数
产品公称通径为10mm，流动方向为单向，密封形式采用软密封设计，确保长期使用中的密封性能。推荐工作温度为-15°C至+70°C，可满足大多数工业环境需求。安装时需注意油液清洁度（建议NAS1638-12级污染控制），并配合25μm以上精度的过滤器使用，以延长产品寿命。1219
应用场景
MPCV-02B/MPCV02B广泛应用于需要保压、泄压或快速排油的液压系统，如注塑机、机床、工程机械等领域。其典型应用包括液压缸位置锁定、大流量排油回路以及立式液压缸的补油控制，能有效防止负载下滑或油路吸空问题。2829
产品优势
天榆液压气动通过优化阀体内部流道设计，降低压力损失，提升响应速度。产品稳定性高，在频繁启闭工况下仍能保持性能一致性。用户可根据实际需求选择MPCV-02B的不同变型型号（如MPCV-02A、MPCV-02W等），以适应多样化系统配置。1926
Product Introduction (English)
The MPCV-02B/MPCV02B is a stackable pilot-operated check valve manufactured by Tianyu Hydraulic & Pneumatic, designed to regulate unidirectional oil flow in hydraulic systems while allowing reverse flow when external pilot pressure is applied. Its compact stacked structure enables easy integration with other hydraulic valves, reducing piping complexity and enhancing system reliability. 1226
Key Features
This valve features a robust cast iron construction and soft sealing mechanism, suitable for medium-to-high pressure applications (up to 24MPa). It supports diverse hydraulic fluids including petroleum-based oils, synthetic fluids, and water-glycol mixtures within a viscosity range of 15-400cSt. The bidirectional control capability ensures efficient pressure maintenance and rapid exhaust in circuits. 2819
Technical Specifications
With a nominal bore of 10mm and unidirectional flow design, the MPCV-02B operates optimally between -15°C and +70°C. For prolonged service life, it is recommended to maintain fluid cleanliness (NAS1638-12 standard) using 25μm filtration. The valve’s modular installation simplifies maintenance and system upgrades. 1226
Applications
Ideal for industrial machinery such as injection molding machines, presses, and construction equipment, this valve excels in scenarios requiring load-holding, fast cylinder retraction, or vacuum prevention in vertical cylinders. Its performance ensures stability under cyclic operations. 2829
Advantages
Tianyu’s engineering refinements in internal flow paths minimize pressure drops and improve response times. The MPCV-02B series offers variant models (e.g., MPCV-02A/W) to accommodate customized hydraulic configurations, delivering consistent performance across diverse operating conditions. 1926
