Product Details

working principle:

HQ41X micro-resistance rolling ball check valve uses a rubber-covered rolling ball as the valve disc. Under the action of the medium, it can roll up and down on the integral slide of the valve body to open or close the valve. It has good sealing performance and noise reduction. The city is closed and no water hammer occurs.

Features:

The valve body adopts a full water flow channel, with large flow rate, small resistance and low faucet damage.

The loss is 50% smaller than the swing type. It can be installed horizontally or vertically and can be used for cooling.

Water, hot water, industrial and domestic sewage pipe networks are more suitable for submersible sewage pumps.

Mass temperature 0-80°C. Can be installed at the water pump outlet to prevent backflow and water
