RVP-25， 单向阀
RVP-25单向阀产品概述
RVP-25单向阀是一种采用锥阀结构的液压控制元件，主要用于防止油液或压缩空气逆向流动。该产品采用板式连接设计，通径为25mm，最高工作压力可达31.5MPa，适用于建筑机械、矿山设备、液压机等工业领域。阀体材质采用铸铁或球墨铸铁，具有良好的密封性和耐压性能，可在-30℃至+80℃温度范围内稳定工作，兼容矿物质液压油及磷酸酯液压油等多种介质。3412
产品功能特点
RVP-25单向阀通过内置弹簧机构实现单向截止功能，当介质正向流动时，油压克服弹簧力推动阀芯开启通道；反向流动时阀芯在弹簧作用下自动闭合，实现零泄漏密封。其锥形阀座结构显著降低压力损失，流量容量可达600L/min。该产品提供直通式和直角式两种流向设计，支持螺纹连接、法兰连接等多种安装方式，适用于液压系统中泵出口背压保护、执行元件锁紧等场景。71014
技术参数说明
该阀公称通径25mm，额定压力31.5MPa，适用介质粘度范围2.8-500mm²/s。产品采用模块化设计，阀芯行程受弹簧座精确限制，确保响应速度与密封可靠性。特殊设计的氟橡胶密封件可适应不同油品特性，工作寿命超过100万次动作。用户可根据系统需求选择标准开启压力0.05MPa或其他定制规格。61317
应用领域与优势
RVP-25单向阀广泛应用于冶金、电力、工程机械等行业的液压系统，特别适用于需要防止驱动电机反转或容器介质泄放的工况。相比同类产品，其优势在于：锥阀结构带来更低压力损失；板式安装节省管路空间；全流量设计减少系统能耗；模块化组件便于维护更换。产品经严格出厂测试，确保在高压冲击和频繁换向工况下的稳定性。2922
Product Introduction in English
The RVP-25 check valve is a hydraulic directional control component featuring cone valve technology, designed for unidirectional flow control in oil or compressed air systems. With 25mm nominal diameter and 31.5MPa maximum working pressure, it adopts flanged connection and cast iron/ductile iron construction, suitable for industrial applications including construction machinery and hydraulic presses. The valve operates within -30°C to +80°C temperature range, compatible with mineral-based hydraulic fluids and phosphate ester media. 31213
Functional Features
This check valve utilizes spring-loaded poppet mechanism to permit free flow in one direction while preventing reverse flow. The cone-shaped seat design minimizes pressure drop, achieving 600L/min flow capacity. Available in straight-through and right-angle configurations, it supports multiple mounting options for pump outlet protection, actuator locking, and auxiliary circuit applications in hydraulic systems. The precision-machined components ensure zero-leakage sealing performance over 1 million cycles. 71014
Technical Specifications
Key parameters include: 25mm port size, 31.5MPa pressure rating, 2.8-500mm²/s viscosity range. The modular design allows easy maintenance, with fluorine rubber seals accommodating different fluid properties. Standard cracking pressure is 0.05MPa with customization options. The valve demonstrates exceptional stability under pressure surges and frequent directional changes through rigorous factory testing. 61722
Application Scenarios
Widely implemented in metallurgy, power generation and mobile equipment sectors, the RVP-25 excels in preventing motor backspin and fluid backflow scenarios. Its compact footprint, energy-efficient full-flow design, and service-friendly construction provide distinct advantages over conventional check valves in demanding industrial environments. 2913
