1. Key Advantages
Zero Water Hammer Protection
Rocker spherical connection design, buffer shock-absorbing when the valve flap closes, effectively reducing water hammer impact, protecting the pump and piping system.
Ultra-low flow resistance optimization
Straight-through flow path design, fluid resistance reduced by 40%, the valve can be opened under 0.01MPa differential pressure, energy saving and high efficiency.
Lifelong maintenance-free
316 stainless steel valve flap + self-lubricating pin structure, resistant to high-frequency opening and closing (more than 5 million times), trouble-free operation for 10 years.
No leakage security
fully closed valve structure (only the center flange needs to be sealed), eliminating the risk of external leakage, in line with ISO 5208 sealing standards.

3. Industry Applications
Petroleum & Chemicals
- Oil pipeline backflow prevention (hydrogen sulfide corrosion resistance, PN40 high pressure design).
- Chemical delivery (316L valve body resistant to nitric acid and acetic acid corrosion).
Food and Pharmaceutical
- CIP cleaning pipeline (mirror polishing Ra ≤ 0.8μm, no dead space design, through the FDA audit).
- Bioreactor media injection (sanitary structure, compliant with GMP Class C).
Energy and Municipal
- Boiler steam system (temperature resistant to 550°C, prevents saturated steam backflow)
- Municipal water supply network (waterproof hammer design to protect the pumping unit).
