天榆液壓氣動YF-B20H4-S溢流閥/YFB20H4S
產(chǎn)品概述
天榆液壓氣動YF-B20H4-S溢流閥（型號YFB20H4S）是一款采用平衡活塞式結(jié)構的高性能液壓控制閥，專為液壓系統(tǒng)中的壓力調(diào)節(jié)與安全保護設計。該產(chǎn)品通過手輪式壓力調(diào)整實現(xiàn)精確控制，具有工作穩(wěn)定、體積緊湊、維護便捷及低噪音等特點，適用于工業(yè)機械、冶金設備、工程機械等多種應用場景。其設計兼顧可靠性與實用性，能夠有效維持系統(tǒng)壓力恒定或防止超負荷運行。916
技術特點
YF-B20H4-S溢流閥可在≤31.5MPa壓力范圍內(nèi)穩(wěn)定工作，環(huán)境溫度適應范圍廣（-20℃至+65℃），推薦使用20號或30號礦物油作為工作介質(zhì)，油溫保持在50±5℃時性能最佳。閥體采用螺紋連接方式，支持在90°范圍內(nèi)靈活安裝，滿足不同空間布局需求。產(chǎn)品內(nèi)置油封保護，有效期為一年，確保長期存放后的使用性能。此外，該閥配備遙控接口，支持遠程控制或多級壓力調(diào)節(jié)功能，提升了系統(tǒng)集成的靈活性。518
產(chǎn)品優(yōu)勢
該溢流閥通過優(yōu)化流道設計降低了內(nèi)部壓力損失，提升了能源利用效率。其關鍵部件經(jīng)硬化處理并精密研磨，抗污能力強，對微小顆粒不敏感，延長了使用壽命。右旋調(diào)壓手輪可增加壓力設定值，左旋則減小壓力，操作直觀簡便。產(chǎn)品適用于多種液壓油介質(zhì)，但需注意過濾精度不低于30微米以保證性能。1420
應用領域
YF-B20H4-S溢流閥廣泛應用于注塑機、機床、液壓站等設備中，作為系統(tǒng)壓力調(diào)節(jié)或安全保護元件。其緊湊結(jié)構和模塊化設計便于與其他液壓閥組合使用，滿足復雜系統(tǒng)的需求。該產(chǎn)品在高壓、高頻工況下仍能保持平穩(wěn)運行，適合對噪音控制要求較高的環(huán)境。68
Product Overview
The Tianyu Hydraulic & Pneumatic YF-B20H4-S Relief Valve (Model YFB20H4S) is a precision-engineered hydraulic control component designed for pressure regulation and system protection. Featuring a balanced piston structure and handwheel-adjustable pressure settings, it ensures stable performance in industrial machinery, metallurgical equipment, and construction systems. Its compact design and low-noise operation make it suitable for diverse hydraulic applications.916
Technical Specifications
Operating within a pressure range up to 31.5MPa, this valve adapts to environmental temperatures from -20℃ to 65℃. Compatible with ISO VG20 or VG30 mineral oil (50±5℃ recommended), it requires fluid filtration ≥30μm. The threaded connection allows 90° rotational installation flexibility, while integrated oil seals provide one-year storage protection. A remote control port enables multi-stage pressure adjustment for complex systems.518
Key Features
The optimized flow path design minimizes internal pressure loss, enhancing energy efficiency. Hardened and polished components resist contamination, ensuring durability. Clockwise rotation of the handwheel increases pressure settings, while counterclockwise reduces it, offering intuitive operation. The valve maintains consistent performance under high-frequency switching without vibration.1420
Applications
Ideal for injection molding machines, CNC equipment, and hydraulic power units, this valve serves as a pressure regulator or safety component in medium-to-high-pressure systems. Its modular construction supports integration with other hydraulic valves, catering to customized fluid power solutions. The design prioritizes reliability in demanding industrial environments.68
