Product Description

Drvz Mute Non Return Check Valve
The HC41XDRVZ silent noise-reducing check valve is mainly applicable to water supply and drainage systems, fire protection pipeline systems, agricultural irrigation systems, etc. This valve is installed at the outlet of the water pump to prevent the backflow of the medium and avoid destructive water energy, protecting the water pump and other equipment in the pipeline. The main performance features of this valve are as follows:
1. The water flow path inside the valve body adopts a streamlined design, resulting in less water head loss. The valve flap has a short closing stroke, enabling rapid valve closure. It operates smoothly, without vibration, noise, and is safe with very few faults.
2. The structure is reasonable and the sealing performance is good.
3. It is wear-resistant and has a long service life.
