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
