GB/T585-2008 Cast steel stop check valve

Stop Valve refers to the valve whose closing part (disc) moves along the centerline of the valve seat. According to this movement form of the valve disc, the change of the valve seat opening of the Cast Globe Stop Check Valve is proportional to the stroke of the valve disc. Because the opening or closing stroke of the valve stem is relatively short, and the valve stem has a very reliable cutting function, and because the change of the valve seat opening is proportional to the stroke of the valve disc, the Cast Steel Globe Stop Check Valve is very suitable for adjusting the flow. Therefore, this type of Stop Check Valve is very suitable for cutting off or regulating and throttling.
