Ductile Iron Low-Resistance Slow Closing Check Valve HH44X-16Q

Product Description

The HH44X low-resistance slow closing check valve consists of a valve body, valve bonnet, disc, valve stem, and regulating valve. Installed at the pump outlet, it prevents backflow of the medium and eliminates destructive water hammer, while effectively reducing water hammer pressure during valve closure, thereby ensuring the safe operation of the pipeline network. It features a lightweight valve, wide opening, low fluid resistance, an innovative water hammer suppression mechanism, reliable sealing, a long service life, smooth operation, and is vibration- and noise-free.

Product Features

1. Low-resistance, slow closing check valves feature a lightweight disc, wide opening, low power consumption, low fluid resistance, an innovative water hammer suppression mechanism, stable and reliable sealing performance, wear resistance, a long service life, smooth operation, and vibration- and noise-free performance.
2. Equipped with a counterweight mechanism. The valve disc offers minimal resistance to water flow when swinging open, and the force required to open the valve is only one-fifth that of the original swing-type valve, making it an energy-efficient product.
3. A damping device is installed in the final stage of the valve disc’s closing stroke, and the damping time is adjustable to prevent destructive water hammer.
4. Innovative rubber-coated valve disc design; reliable sealing; corrosion resistance; vibration damping and wear resistance; long service life; smooth operation; low noise.
