It is open when the ball's hole is in line with the flow and closed when itis pivoted90-degrees by the valve handle. The handle lies flat in alignment with the flow when open,and is perpendicular to it when closed, making for easy visual confirmation of the valve's status.In the case that a ball valve is used for cryogenics or product that may expand inside of the ball, thereis a vent drilled into the upstream side of the valve. This is referred to as a vented ball. Safety is thenumber one concern when engineers specify a vented ball.Marks: A ball valve should not be confused with a "ball-check valve", a type of check valve that usesa solid ball to prevent undesired backflow.Hot-Selling Brass Valves                                         About our factory                                                   Perfect Pre-sale and After-sale Service                FAQ                                                                        Q: Are you trading company or manufacturer ?A: We are a trading and manufacturer company.Q: Do you have standard products?A: Yes, we have standard products.
