Our offered ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. These are open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle of our products 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. These are made with, but are not limited to, any of these materials like Stainless steel, Brass, Bronze, chrome, titanium, PVC, etc. We make them according to our customers requirements.
