英文介绍：
Tianyu Hydraulic & Pneumatic DF-20H Right Angle Check Valve is a high-performance directional control component designed for industrial fluid systems. Featuring 90-degree body configuration, this valve optimizes pipeline layout efficiency while ensuring unidirectional flow control. The precision-machined conical poppet and seat assembly effectively prevents medium backflow in hydraulic/pneumatic systems, maintaining operational stability.
Constructed with high-grade alloy steel body and multi-layer sealing system, the valve demonstrates reliable performance within temperature range of -20℃ to 120℃. The optimized flow path design reduces pressure loss by 18% compared to conventional models, with operational pressure spanning 0.3-31.5MPa. The compact right-angle structure saves over 25% installation space versus straight-type check valves, making it ideal for complex piping arrangements.
This product excels in construction machinery hydraulics, metallurgical pneumatic controls, and injection molding machine circuits. Rigorous testing confirms 200,000-cycle durability with consistent sealing integrity. Environmentally friendly electroplating surface treatment enhances corrosion resistance for standard industrial environments. Available in G1/4 to G1 port sizes to accommodate various flow requirements.
Manufactured using CNC machining centers, the valve achieves dimensional accuracy within ±0.01mm tolerance. Simplified maintenance design allows disassembly with standard tools, while interchangeable sealing elements facilitate cost-effective servicing. The product s adaptable configuration supports horizontal/vertical installation orientations without compromising performance.
