Description: A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is 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 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. Features: Valve bodies are made of 304 stainless steel for rust protection and long service life. Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. Ball valve's ease of operation, repair, and versatility lend it to extensive industrial use. Handle lies flat in alignment with the flow when open and perpendicular when closed for easy visual confirmation of valve's status. This high quality ball valves would be excellent choices for shutoff and control applications.
