Butterfly Buffer Check Valve

The Butterfly Buffer Check Valve, launched by Dafugui factory, has garnered widespread attention for its excellent sealing and wear resistance. Its most significant feature is its "buffer design." A built-in buffering mechanism gradually adjusts the opening and closing speed of the butterfly disc, eliminating the sudden "wall-slamming" of the water during pump startup and shutdown, effectively dissipating the impact of water hammer. The disc and seat of this check valve fit securely, and the buffering structure ensures quiet, vibration-free operation.

Core Advantages

The most significant feature of our Butterfly Buffer Check Valve is its unique buffering design. When closing the valve, it does so slowly and steadily. This slow and steady buffering process minimizes water hammer pressure.

For this Dafugui valve, we've invested significant effort in optimizing the internal flow path, coupled with precision manufacturing techniques. The result: Whether opening or closing, the entire process is vibration-free and virtually noiseless.

The most important aspect of a valve is its sealing. We use high-performance sealing materials, combined with our sophisticated butterfly structure, to ensure zero leakage once the valve is closed.
