GB/T1951-2008 Low pressure external thread bronze stop valve  

Stop Check Valve refers to the valve whose closing part (disc) moves along the centerline of the Valve seat. There are some things to pay attention to. First, the Cast Steel Globe Stop Check Valve operated by the hand wheel handle can be installed anywhere in the pipeline. Second, the flow direction of the medium of the Stainless Steel Stop Check Valve should be consistent with the arrow direction shown in the valve body. Finally, it should be noted that the flow resistance coefficient of Stop Valve is relatively large, which will cause pressure loss, especially in hydraulic devices. It is packed in wooden cases with bubble film inside to prevent falling.
