3-Way Ball Valves are available as an L Port or T Port can be used in heating and hot water applications to regulate temperature. The valves control the flow of liquid passing through them to either allow flow in one direction or another, or divert flow from one path to another. Our stainless 3-Way stainless steel ball valves come pre-tested so you can get them up and running immediately. You will also receive a two page test report detailing all opening/closing times after your order has been completed. By switching from conventional ball valves to our low torque AV-L5300MA & 5400MA 3-Way Ball Valve, you'll save money on installation costs and maintenance while improving overall reliability. Our product is designed with the end-user in mind and we understand what works best for industrial automation.
