NameNon-Abrasion BALL CHECK VALVE Type : HQ41X Nominal Diameter : DN50—350 Pressure Class : 1.0MPa—1.6MPa Suitable Temperature : LESS THAN 80 DEG Suitable Medium : Water Material : CAST IRON ,BALL IRON,WCB
Structural feature
Our Shangri brand HQ41Xtype ball check valve, which adopts
rubber-coated rolling-ball inner valvedisc, when effected by the
medium, it may roll around on the whole slidewayof valve body,
accordingly opens or shuts the valve. At the same time ofnoise
abatement shutting, no water hammer and good seal, the valve
bodyadopts full passage, which results in big flux, small
resistance and waterwaste 50% less than the turning one. It may be
installed horizontally orvertically, and is applied in the pipe net
system of cold water, hot water,industrial&living water, and
specially submerged drainage valve as wellwith the medium in 0-80℃.
