Energy-saving Silent Check Valve（Projectile Type）
The body cavity adopts a streamlined design, with a flowrate of 100%,reducing sharp bends, corners, and sharp protrusions, thereby reducing resistance.
The valve disc is designed with a conical shape, greatly reducing resistance and minimizing noise caused by turbulence.
The closing stroke of the valve disc is short, only 1/4 of thenominal diameter, reducing the closing time of the valvedisc and minimizing the generation of water hammer.
The spring to accelerate the closing speed of the valve discand reduce the generation of water hammer.
