HQ41X micro-resistance, non-wear spherical check valve

HQ41X Spherical check valve Overview

The spherical check valve uses the rubber coated rolling ball as the valve disc. Under the action of the medium, it can be rolled up and down on the integral slide in the valve body to open or close the valve. Silent closure, no water hammer, good sealing performance. The valve body adopts the whole water flow channel, the flow is large, the resistance is small, the water head loss is 50% less than the swing type. Horizontal or vertical installation can be used in cold water, hot water, industrial and domestic water pipe network system, more suitable for the use of submersible drainage pump, the medium temperature is 0 ~ 80ºC.
