Flow-Tek, a subsidiary of Bray International, has introduced a new line of multiport ball valves – the Multiport Series. Offering 3-way and 4-way flow control, Multiport Series valves are available in two different body styles, a compact standard port and a block style full port. Multiport Series ball valves feature multi-directional flow combined with shut-off capacity in one valve. Valve duplication and the need for an extra shut-off valve are eliminated. Standard applications for Multiport Series valves include mixing or blending of line medias; diversion of flow to different location; bypass of flow around strainers, meters, and heat exchangers; direct flow out-of or into storage tanks; and shut-off flow from different directions. Valve bodies are available in standard and full port, 1/4″-8″, in stainless steel and carbon steel construction. Pressure ratings range from 800 psi to 1000 psi depending on size. Standard port valves are available with NPT threaded and quick clamp end connections. Full port valves are available with NPT threaded, quick clamp and flanged end connections. As a special added feature, full port valves are also available with socket weld or butt weld end connections on sizes 1/4″ to 4″. Many parts are fully interchangeable between models. Stem seals in Multiport Series 1/4″- 4″ valves feature a live-loaded stem packing assembly for positive sealing.
