YQ98004 type filter piston type slow closing check valve installed in the tap water factory and high-rise building water supply system, water supply system and other water pump outlet pipe, to prevent the media back, to prevent the emergence of the phenomenon of water hammer and the water hammer. A valve with electric valve, check valve and water hammer eliminator, can effectively improve the safety and reliability of water supply system.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.

1, eliminate water hammer effect is good. The slow opening and closing of the technical principle of the elimination of water hammer, integration, to prevent the opening of the pump water hammer and stop pumping water hammer.
2, easy to operate. Only need to operate the pump motor on-off button, the valve or pump operating procedures in accordance with automatic opening and closing.
3, energy saving effect is good. The valve body adopts the full channel flow line direct current design, the pressure loss is small, the flow is big, the volume is small, the weight is light.
