RVP-25， 單向閥
RVP-25單向閥產(chǎn)品概述
RVP-25單向閥是一種采用錐閥結(jié)構(gòu)的液壓控制元件，主要用于防止油液或壓縮空氣逆向流動。該產(chǎn)品采用板式連接設(shè)計，通徑為25mm，最高工作壓力可達(dá)31.5MPa，適用于建筑機械、礦山設(shè)備、液壓機等工業(yè)領(lǐng)域。閥體材質(zhì)采用鑄鐵或球墨鑄鐵，具有良好的密封性和耐壓性能，可在-30℃至+80℃溫度范圍內(nèi)穩(wěn)定工作，兼容礦物質(zhì)液壓油及磷酸酯液壓油等多種介質(zhì)。3412
產(chǎn)品功能特點
RVP-25單向閥通過內(nèi)置彈簧機構(gòu)實現(xiàn)單向截止功能，當(dāng)介質(zhì)正向流動時，油壓克服彈簧力推動閥芯開啟通道；反向流動時閥芯在彈簧作用下自動閉合，實現(xiàn)零泄漏密封。其錐形閥座結(jié)構(gòu)顯著降低壓力損失，流量容量可達(dá)600L/min。該產(chǎn)品提供直通式和直角式兩種流向設(shè)計，支持螺紋連接、法蘭連接等多種安裝方式，適用于液壓系統(tǒng)中泵出口背壓保護(hù)、執(zhí)行元件鎖緊等場景。71014
技術(shù)參數(shù)說明
該閥公稱通徑25mm，額定壓力31.5MPa，適用介質(zhì)粘度范圍2.8-500mm²/s。產(chǎn)品采用模塊化設(shè)計，閥芯行程受彈簧座精確限制，確保響應(yīng)速度與密封可靠性。特殊設(shè)計的氟橡膠密封件可適應(yīng)不同油品特性，工作壽命超過100萬次動作。用戶可根據(jù)系統(tǒng)需求選擇標(biāo)準(zhǔn)開啟壓力0.05MPa或其他定制規(guī)格。61317
應(yīng)用領(lǐng)域與優(yōu)勢
RVP-25單向閥廣泛應(yīng)用于冶金、電力、工程機械等行業(yè)的液壓系統(tǒng)，特別適用于需要防止驅(qū)動電機反轉(zhuǎn)或容器介質(zhì)泄放的工況。相比同類產(chǎn)品，其優(yōu)勢在于：錐閥結(jié)構(gòu)帶來更低壓力損失；板式安裝節(jié)省管路空間；全流量設(shè)計減少系統(tǒng)能耗；模塊化組件便于維護(hù)更換。產(chǎn)品經(jīng)嚴(yán)格出廠測試，確保在高壓沖擊和頻繁換向工況下的穩(wěn)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
