5. Check Valves – Backflow Prevention Safeguards

Check valves automatically block reverse flow to protect pumps and compressors from water hammer and contamination. YYF develops anti-jamming designs for chemical media:

Technical Advantages:
- Swing-type discs with guide vanes lower minimum activation pressure to 0.03MPa, suitable for high-viscosity (＞1000cP) material transfer;
- Stellite alloy overlay on seats extends erosion life to 15 years, ideal for slurry systems with solid particles;
- Rubber buffers reduce water hammer pressure by 70%, protecting precision instruments and pipe welds.
Applications: Reciprocating pump outlets, compressor inlets, reboiler inlets—critical for media with polymer crystals or catalyst particles.

6. Butterfly Valves – Efficient Large-Flow Regulation

Lightweight and fast-acting, butterfly valves are ideal for large-diameter (DN800+) flow control in chemical plants. YYF offers double-offset metal or EPDM soft seals:

Technical Advantages:
