H42W Stainless Steel Vertical Check Valve product details

H42W Stainless Steel Vertical Check Valve product description

H42W Stainless Steel Vertical Check Valve produced and sold by Baigang valve group is normally closed, due to the pipeline inlet medium pressure, and overcome the spring resistance to open the valve. When the inlet side of the medium pressure is lower than the outlet end, the spring will push the spool to the valve seat to close the valve to prevent the media countercurrent, it played the role of check. The valve due to the use of spring support spool, so the use of vertical or horizontal installation can be installed.
